Nitrate and Ammonia line graph!
 (Catie and I had the same fish tank)

May 23

The changes, slowly but surely, were definitely for the better.  We didn't start our very well with pretty high ammonia and nitrate.  Our plants that we added really grew a lot over time and grew new stems or leaves just by over night sometimes!  So we went from 0 plants to 3!  I remember when we started out, our water was never clear.  That tank, I figured, was not used as much as the others so the rocks were very dirty and when we sifted through the rocks in the beginning over and over the tank still turned out dirty when we put the water in.  On this date however you would see our tank as clean a crystal because we did a full water change and siphoned it every week!  Even with the hard work overall ten fish did die.  Technically though, it wasn't really our fault.  We took pretty good care of them, but most died from the filter being to strong (killing two of our fish), Mrs. Wood giving me the bacteria instead of the dechlorinator (four fish died), and the rest died from stress from when we got them, to putting them in the tank.  

May 22

I have learned a lot from our aquarium project!  I would say that I've never even knew how hard it was to keep a fish maintained and totally underestimated how much it takes to keep the ecosystem of your tank under control. 1.) You have to do ammonia, nitrate, dissolved oxygen, pH, and Alkalinity tests to make sure the environment is stable enough for your fish to survive in.   2.) I learned that tap water can kill your fish and that you must use declorinator and bacteria when adding fish or your fish could die! (don't get those two mixed around though, that could be bad!:P) 
3.)  Fish must have oxygen.  I had no idea that we needed a bubbler to keep our fish alive but now I do. 4.) Different fish do not get along with each other whereas I thought every fish would be fine and playful. (one of our fish lost an eye in the beginning because others didn't like him- even though those we picked were supposed to "get along"). 5.)  Different fish act differently and like other places of the tank and tend to stay or swim in that area.

I would change this project for next year by letting everyone know that a filter can be bad for small fish.  We put a filter in our tank and it killed two of our fish because it was too strong and sucked them up:( I would also change how we learned how to take care of them after we got them.  Going into it we were really confused on what to do at first and what it took to help them survive haha.  The guys at pets mart said only certain fish could live at certain temperatures and some fish had to be in groups and most fish you added wouldn't survive if you added more than five fish or such. We went to pet co first and didn't learn this until later. In our group we had three people and that was difficult because some people wanted different fish, but some fish needed to stay with a certain group.  Overall though it was pretty fun! It was also very sad though! I did not want to lose so many fishies:(

May 21

 Our aquarium was going pretty good on this date!  Our temperature was fine and was around 76 degrees Fahrenheit and 25 degrees Celcius.  We added another plant to bring our nitrate down because it was too high(10).  But our ammonia was very good at 0!  This means that we were taking good care of our tank and the ammonia level means the siphoning and water change paid off!  For observations I wrote down that Catie's fish was actually skinnier it looked like and one of our shrimp went missing!  We never did find his body or anything so it's a mystery. (I don't remember Mrs. Wind saying that shrimp jumping a tank was possible but who knows haha).  But overall, not bad!

The Autumn Olive(emergent) is 20 feet in height.  Leaves are dark green and untoothed.  The underside is covered with silver-white scales.  The flowers are light and yellow and are borne along twigs after the leaves have appeared early in the growing season. Due to the nitrogen-fixing capabilities it has the capacity to adversely affect the nitrogen cycle of native communities that may depend on infertile soils.


The Oxygen Weed has numerous threadlike roots, which are adventitious (branching from the stem) and, along with rhizomes (horizontal stems in the sediment), anchor it to the bottom.  This plant grows supper fast and takes up most of the oxygen for fish and hurts the ecosystem.


Duckweed is a free floating plant that has individual fronds that produce fine roots.  Mature fronds appear 1.5 to 2 times longer than wide, with widths measuring from 1-3 or five mm. Fronds are narrowly egg-shaped to slightly kidney-shaped and intensely green in color. As a problem it can become a serious nuisance due to its rapid colonization, easy distribution and quick dispersal rate.



These invasive plants are more troublesome than it's natural home because people aren't accustomed to them in different areas whereas where they used to be, people developed different ways to lessen or get rid of them.

May 17

Our water quality throughout has been pretty good!  Overall we've taken very good care of them.  Some issues we had was when it got dirty we siphoned it and one time we did a full water change when four of our fish died. This was because our tests were kinda bad at first but we did succeed to get it to a normal level. Most of our fish died because Mrs. Wood gave us the wrong bottle on accident. It was supposed to be the dechlorinator but she gave us the bacteria instead!  So that showed us how important the water quality test is and to keep our tank well maintained.  After that there was a point our Nitrate was too low so we had to steal plants from anothter tank to keep it balanced.  Sadly, right when our tank was at the normal level and perfect we had to take them all home or give them away): However, we learned so much about different algae and polution, about nitrate and ammonia, dissolved oxygen, and the pH of the water during this interesting project!

This day we did not do a water quality test, we did power point presentations.  But what we did do was a complete water change and clean the rocks of our tank because our fish died and we got even more fish.  We did not want to lose another fish ever again!   Our fish freaked out when we put them in a different container with the volcano as the bubbler, but it was for the best! The different fish we got was a guppy, a snake like fish, and two ghost shrimp.  Our snail, Gary, once we put him back in, went into shock.  Apparently the water change was to much for him and he had died the next day.  We all literally work so hard so please give us a good grade.  We do not kill our animals on purpose!  We added this big rock looking thing for the fish to swim in between and the two Platties that we have, when we put them back in, swim next to each other always and were never someplace without the other.


This is the snake looking fish, he is on the wall of it.

An ecosystem that is self-sustaining means that it is able to adapt and take car of itself, sort of like how a plant doesn't need fed and can make its own food.  This term does not describe our aquarium in many different ways.  First, the ecosystem of our aquarium would falter and become unhealthy if we didn't test the water for ammonia, nitrate and pH.  So then we would know whether to change out the water, add more plants, add dechlorinator, etc.  Second, our fish are not available to outside resources so we need to feed them ourselves or else they would die.  In order for our ecosystem to become independent, we would have to set up timed tests that would happen automatically and timed feeding or put them in a lake or someplace where they'd do everything themselves.

The nitrogen cycle is the process where nitrogen goes through chemical changes. This transformation can be carried out through both biological and physical processes. The processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification. When plants and animals die, bacteria convert nitrogen nutrients back into ammonia salts and ammonia. The step of Fixation includes bacteria conversion that is necessary to convert gaseous nitrogen into forms usable by living organisms, which makes nitrogen a crucial component of food production.   It is not possible to not include plants, animals or bacteria because if they're wasn't any of these, the cycle couldn't go onto the next step.

5/13/12

Our water quality consisted of our ammonia being zero, our nitrate being 5.0, the pH was 8.4 and it was 76 degrees Fahrenheit.  This would probably compare to a lake with a lake being higher in both ammonia and nitrate because there is lot more fish that go and more plants.  In a river it would vary because the ammonia probably get swept away. So the water quality in the river would probably be better but not as much as in an aquarium because humans can control the balance in that situation but not in natural lakes or rivers.

Aquarium Update

Our aquarium is doing pretty well! We did our Ammonia and Nitrate test and the Nitrate was 5.0 and our ammonia was .25 which is pretty darn good!  The ammonia is the amount of pee or poop is in the tank and so we've brought it down from 1.0 to finally to a good level! The temperature was 71 degrees Fahrenheit and we did not do a water change I don't think... We observed that the Red Platty and the Mickie mouse fish poop a lot so it was surprising to see our ammonia so low.  The two plants are also growing very well.

  My fish is the back one, Catie's is the one nearest to the plug and the Glow Fish is the yellow one (which is Baileys.)

5/10/13

Well since this is a late update I might as well inform that four fish have died.  Mrs. Wood gave me the bacteria instead of the dechlorinator when I siphoned our tank (which we're supposed to be doing everyday) , and fish cannot survive without the dechlorinator and since we aren't checking the tanks over the weekend, we didn't have a chance to figure out that I put in bacteria.  It's just very frustrating because we have had at least ten fish die already and we do everything we're told but I guess it's just bad luck.  We don't purposefully kill our fish I promise. Anyway our last quality check was very good (before the dechlorinator incident), our Nitrate was 5.0, ammonia was 0, temperature was 74 degrees.  So everything checks out pretty well the ammonia can be bad for the fish if it was too high so that's good, Nitrate should be about 5 too.  So this proves we are taking care of our fish! We did the water change about two days after the test because the floor of the tank was filthy.  I still feel awful about our fish dying but I guess accidents happen.

To use a dichotomous key you have to go through a series of numbered statements that describe a certain type of algae or anything really.  Then once you find all the ones that the numbers match, that's what you're looking for. (hard to explain)   For each number there is a choice like a.) colorless....2 or b.) colored.....6.
Then you go to the number for whatever is a true characteristic on what you're observing (we observed algae for example).  You keep on matching the statements with what you observe until you come up with a name of what it is in the end, telling you what your item is called.  The purpose of this is to learn the different characteristics of what you're trying to classify and how they are all unique from the others or similar.  When making our dichotomous key in class, we looked at how some algaes were similar and different.  The problems we ran into were trying to find something that would apply for one algae and not the others and coming up with different characteristics that were not on the chart.

Assessing Water Quality

To asses the water quality of a body of water, there are some steps you would need to take.  First, you would observe the water and judge if it looked polluted or if it had an algae bloom for example.  Next take a sample of the water and see if it has any algae.  The different kinds of algae you find may show if it is healthy or unhealthy water.  Thirdly, test the temperature, ammonia levels, dissolved oxygen, nitrate levels, and pH.  After that if you wanted you could run different types of chemical tests on the water also.  It is important to do all these steps in order because I'm assuming to run all of these tests would cost you a lot of money!  If you observed that the water was unhealthy first and was dirty with pollution you were probably right!  Or algae blooms are easy to spot too!  If that's not good enough you can take a water sample and observe it underneath a microscope you can find different types of algae. Some are more resistant to pollution such as Anabaena, which would mean it would be poor quality water.  If you found Stigeoclonium (which helps clean the water) it's more likely to be a healthier quality body of water.

Dissolved Oxygen and Carbon Cycle.

Two sources of dissolved oxygen would be the oxygen from the plants in the water and the oxygen and its contact with the atmosphere.  During the day the oxygen levels rise (because photosynthesis occurs with sunlight) and the carbon dioxide levels decrease as the plants absorb it.  During the night carbon dioxide increases while oxygen decreases.  This is because their is no sunlight to create photosynthesis, and therefore oxygen. However, the plants instead of producing oxygen, absorb it and produce carbon dioxide.

5/6/13

Dissolved Oxygen

The term "dissolved oxygen" means the amount of oxygen dissolve in a body of water as an indication of the degree of health of the water and its ability to support a balanced ecosystem. The oxygen comes from plants in the water and also contact with the atmosphere as well.
Steps to do a dissolved oxygen test:
1.) Put water filled to 25 mL into a container.
2.) Get tube with a sort of yellow water and place it in the sample.
3.) Then break off the tip of it.
4.) Let it sit in the water for a few seconds.
5.) After you removed it place your finger on the removed tip and turn it upside down over and over.
6.) After mixing it up let it sit for about 2 minutes.
7.) Compare results with the chart.

Our results showed about 9 mL which is good because if the oxygen was less than 3 mg/l it would not support the fish. In a small pond it would probably hold more oxygen than in an aquarium because there would be more plants.  A large river would have probably the most dissolved oxygen because a fast current allows more oxygen than a lotic system such as a pond.  A pond would also probably be warmer which warm water holds less oxygen.

Aquacheck!

The Aquacheck has five components which are free chlorine, total chlorine, total alkalitnity, total hardness and pH.  Free chlorine refers to the ions that are free in the water, total chlorine is the combination of free and combined chlorine, the buffering capacity of water is total alkalinity (or resistance to pH), total hardness is dissolved minerals in the water, and pH is how basic or acidic the water is.  It can range from 0-14, zero being most acidic, 14 as basic, or 7 as neutral.  These checks are important to know the quality of an aquatic environment.
Our aquacheck turned out pretty well! Our free chlorine was zero as well as total chlorine.  The total hardness was 425, the total alkalinity was 240 and the pH was 8.4.  The pH levels are great because a pH of 3 kills the fish and ours was way high than that. The pH should range from 6-8. Our free chlorine and total chlorine is great that it's zero because chlorine can kill the fish. The hardness is good because they need hard water to survive.  The alkalinity relates to the pH and is okay for the fish but is not the best the best would be maybe around 350 (I think Mrs. Wood said but it's hard to remember). However our tank seems to be a pretty healthy environment so far!

Our fish are a variety of different species.  Mine are the Neon Tetra and the Red Wag platy  Catie has the Mickie Mouse fish and Bailey has the three Glow Fish and a snail.

My fish info.

The Neon Tetra is a pelagic freshwater fish native to trapical parts of South America and orginates from Brazil, South America, and eastern Peru and can also be found in the River Amazon, Tiger, and Napo and Yarapa. It has a spindle shaped body and a blunt nose and a neon blue line that runs on either side of the body with a red line doing the same only placed on the middle of the body down to it's fin.  If the neon blue stripe dulls or looks dim in the light, that may mean your it is ill or stressed. Over 1.5 million Tetras are imported into the U.S. alone, each month!

1. Soft acidic water is the best condition for this fish.

2. The neon tetra is not easy to keep alive because it can develop an incurable Pleistophora disease. 

3. These are omnivores and can eat algae and can eat things such as freeze-dried blood worms too.

4. Our Neon Tetra is normally more comfortable in a group of its own kind but the other ones we had died.

5. It has no eye on one side of it's head and we believe it got into a fight.

6. Can grow up to 1.5 inches.

7. Preferred temperatures from 73 to 79 degrees F.

8. I observed that he stays very close to the front glass.

9. He doesn't play with the other fish or chase anyone.

10. A light over the tank is required so they can see their food clearly.

The Red Wag Platy is a solid red with black tipped fins and black lips.  At first when born the Platy does not have black tipped fins, it's more of a yellow, but when they get older the black fills in. He originates from Eastern Mexico, Guatemala and Northern Honduras.

Requirements/Behavior

1. Platies should have plenty of plants in their environment.

2. A good filtration system is needed for these fish.

3. These fish are omnivores and need algae to feed on.

4. You should change the water 20 to 25% every week.

5. They can live with any other peaceful community fish (like the ones we already have)

6. The male we have can reach up to 1.5 inches.

7. I observed that it swims very slowly and not as fast as the others.

8. I also observed that it gets along with the Mickie Mouse Platy more than any other fish.

9. He goes a lot.

10. He moves very fast when food is in the picture and has a big appetite.

Aquatic Science Field Trip!

My field trip experience was awesome!  I was really glad that my friend Victoria was able to come too because she really wanted too but her teacher wouldn't let her go on the bus when the announcement was made.  But she got a ride there and it turned out well! It was a lot of fun and we got to see many different animals and fish.  The most interesting thing that I saw was the Sea Manatee.  It was a ton bigger than I thought it would be and it was really cool to see one as it swam by.  I learned that the tree kangaroo that we saw was endangered, the burrowing owl really has three different calls and doesn't hoot, the Giant River Otter has adapted webbed feet and a narrow body for swimming against currents, the yellow-banded poison dart frog resides in Venezuela, Guyana, and South America, lastly the Manatee is endangered and need air but can stay underwater for up to twenty minutes. I would have liked to have stayed longer because I missed the Moon Jellyfish and the other animals in the dark room.

                                                                  Pollution Index Chart

The purpose of the Pollution Index Chart helps to tell how clean and healthy the environment is due to the amount of algae. If you do the math which is the number of algae you find divided by five, then only using the a whole number it can divide into multiplied by the number on the pollution index chart, you can figure how polluted the water is. The benefits is you can tell how clean and healthy the environment is, a negative would be is that you're only sampling a portion of the area so the results might not be very accurate.  If the numbers that you get from the math are lower than 14 than the pollution is low. If the numbers are 15-19 than the pollution is probable. Lastly, if the number you get is greater than 20 than the pollution is high.  If the diversity of algae is low but the population of a certain algae is high the water is polluted. If the diversity of algae is is high but the population is low than the environment is healthier and clean.

What we have learned about algae organisms.

I learned a ton about algae this week. The various species of algae help determine water quality because some algae love pollution and would be found in an unhealthy environment, while others are found in healthy environments and clean the water.

Batrachospermum is an algae organism that is found in shaded water, soft water, no sun and cold water.
This particular algae also an indicator of clean water.


Euglena is the number one organism capible of living in poluted water/
It has an eyespot that is a photo-receptor cell that tells the Euglena where the light is for photosynthesis.


Oscillatoria is the second most tolerant to pollution.
It's name comes from the filaments that glides back and forth on it.

April 25

To focus an item in high power you will use the scanning objective which is the lowest magnification.  Then you will move to the low power objective once you've focused on it, then you can move to the high power objective.  To make a wet mount, you will take a piece of algae that can fit on the slide with a couple of drops of algae water and make sure it can fit underneath the cover slide.  To stain the slide you get the right sized iten and add 1-2 drops of stain and gently put the cover slide on top.  You will also use small paper towel and move it around underneath the slide to get rid of the excess water.  I didn't understand before the different parts of the microscope and now I know better how to properly view an object or organism.

Um I'm pretty sure Mrs. Wood has our notes on the video but she lost them and did not return them so I will just get facts of amphibians from the internet.

1.) Amphibians are devised into three groups: frogs, toads, and caecilians.
2.) There are 5,000 to 6,000 known amphibians alive today.
3.) The first Amphibians appeared approximately 370 million years ago during the Devonian Period.
4.) The largest Amphibian is the largest Chinese giant salamander.
5.) The largest number of threatened Amphibians are found in Columbia, Mexico, the Caribbean, and Ecuador.
Amphibians are reliant on water because they need it to reproduce and to protect their eggs which do not have protective shells.  When assessing water quality, Amphibians are an important consideration because the healthier the place is, the more populated that area will be of Amphibians.  If their population is decreasing, it commonly means the water is bad.

This is the Chinese Giant Salamander.  (crazy right)

A water shed is when portion of the water falling on the land seeps into the soil or flows over the surface before entering streams and lakes. The land area that supplies water to a particular river or lake is called a watershed. We (Flower Mound) live in the Trinity water shed.  Our community benefits  from the enhanced sustainability of our land by an increasing infiltration of rainfall while reducing erosion. It also helps provide for agriculture, human consumption, industry, flood control and recreation when we manage watersheds and the water it produces.  This is why our watershed is very important.

Freshwater organism: Snapping Turtle

Scientific name: Chelydra serpentina 

Description: The snapping turtle is characterized by a large, rigid 

upper shell and a much smaller lower shell. It also has a very long saw toothed tail,
eyes which can be seen from directly above the head, and relatively smooth skin on top
of the head. The upper shell is tan or brown and frequently covered with mud and
algae. The lower shell is white or yellowish. The head, limbs, and tail are all brown. Females
may reach a slightly larger size than males.
Behavior: It is highly aggressive when defending itself. Whenever picked up or messed with, the snapper shoots its head forward with incredible speed, and it's mouth wide open. The jaws close with a loud crunch when the neck reaches its full length and if it grabs something it does not let go easily. 

Habitat: It is found in every aquatic situation, but prefers water with soft mud
bottoms, abundant pond vegetation, and sunken logs and branches.
Diet:  It's diet is composed of aquatic or semi-aquatic fish, amphibians fish, amphibians, crayfish, crabs, clams, snails, earthworms, insects, small mammals, unwary birds, snakes, small turtles and carrion, which is dead fish. The will also feed on plants such as Elodea, Polygonum, Nuphar, Nymphaeca and Typha.  It even eats snakes and other turtles.
The main threat to the snapping turtle is humans. In some areas humans hunt for their meat and eggs.  Also adult females are often hit by human cars. This has a negative effect on thier population because it takes a long time for females to reach maturity. Turtle eggs are also hunted by raccoon, foxes, skunks and large birds.

I chose this topic because when I was really young, my next door neighbor actually caught a snapping turtle on the side of the road once in Ohio. Then he released it back somewhere safe. How he caught it, I still have no idea.  I remember poking it with a stick and the turtle snapped it in half.

Are aquarium is better than it was ammonia nitrate wise but our fish arn't doing so well.  Four of our fish have died and they were all tiny Tetra fish.  We learned that tetras are not easy to take care of (we are doing everything right but they still died).  We also have Baileys small snails that are doing okay so far. But one wont come out of it's shell because we think it stressed out when we accidentally siphoned it up... whoops.  But our other one seems fine; it's actually moving around in our tanks. ONe of our yellow fish and red fish likes to hide behind a certain plant in the corner. Our water quality tests are also getting better each time.
4/9: Nitrate was 5.0 and Ammonia was 1.0
4/15: The Nitrate was 2.5 and Ammonia was .50
4/19: Nitrate was 5.0 and Ammonia was .25!
(except our nitrate went up again on 4/19)
This means our tank is cleaner because the poop factor went down I guess.  To make our tank cleaner we also added bacteria.

Pond Organisms

In our lab experience today we found a lot of small organisms. The first one is a tiny round organism that's very hard to see.  The second one was a very small worm. Worms can be differentiated by their small proto-legs and distinct heads. And the last one we found was dead and was a little shrimp. The shrimps "Wings" are revealed to be 11 pairs of appendages that undulate and act as paddles. We did not add any organisms to our aquarium except for a snail that we found.  The snail is doing fine and is crawling around our tank.

Biological illustrators

are artists who draw scientifically correct

pictures of plants and animals. Some artists draw free-hand and some

use computers to create graphic art. They are important to the environment because they can draw what the creatures are and how to improve marine life by giving these drawings to aquatic helpers.

Law enforcement personnel are needed in the environmental field to

enforce the laws protecting our natural areas and wildlife. This is important to the environment because with out rules prohibiting littering or dumping any sort of waste into a marine environment, the organisms would not have a healthy life and a very unsecure environment.

Librarians

work in public and school libraries, private companies, and

government agencies, keeping track of and adding to the collections

of books, journals, maps, photographs and other materials. These people help

people find information both within and outside of the library about aquatic life and help them understand how important is is to everyone.

April 15th (Week 3 blog)

These three things are key to the basic concept of ecological succession because ecologogical succesion means change in the species structure of a ecological community over time. Which is basically what's happening above. The community begins with few plants and animals and developes through increasing complexity until it becomes a stable community. 

This is helpful in the study of freshwater ecology because it helps to understand how plants and animals adapt and produce a stable living condition for the community. 

The term Eutrophic describes our aquarium because we have a lot of fish and no more reproduction and a stable environment for our fish to live in.

I think Lewisville lake has Mesotrophic because they may have a lot of fish that produce more fish and a lot of plants that grow from underneith.

"Freshwater Ecology" is the study the relation ships between freshwater fish organisms and their natural and cultural environments in freshwater lakes, ponds or rivers.  It's important to study because if the water isn't correctly taken care of or interfered with, it can hurt many creatures and affect our lives too.  Freshwater is basically the bane of our existence  and yet much of it has been destroyed through pollution or drought.  It is very important to study to keep freshwater safer, improve it and keep it apart of our lives.

Differences between a pond and a river. 

• A river has running water and a pond has standing water.
• A pond does not disperse water into other bodies of water but a river does.
• In the middle of the river there are more plants whereas on the outside edges of ponds their are mostly plants.
• Ponds contain floating plants that hold still whereas rivers have hold fast plants that cling on for dear life.

What I learned about the Water Issues project

5 main things I learned is that 

1.) Meat contains much more water than a salad. (500 gallons)

2.) Conserving water is important so we all don't run out.

3.) Some ways to conserve water is to turn off your sprinkler when it's raining, time your showers, and fill up your sink when you wash the dishes, instead of keeping it running.

4.) Another thing that I learned is that the lake over by the park is pretty gross and has algea growing all around it.

5.) Lastly, I learned Zebra Mussels can get stuck in peoples boats and they actually have warning about them at lakes.

The best presentation was, I thought, Victoria, Meagan and Joe's presentation. They all took a video and did a lot of research about their project. I thought it was good to inform us about the lake and what others are missing health wise.

On our assignment I think it would have been easier to maybe to a news report on global warming to get in more information in our presentation.

Wed. 4/10

Our aquarium wasn't as clear as we liked it the first time we sifted through the rocks and stuff.  So we decided to start over and redo everything and clean it all over again.   After we cleaned it it was much clearer and we were satisfied.  When we did the ammonia test for the first time it was pretty bad with a 1.0. Being on the green side meant the tank was not habitable for our fish.  Our nitrate test was pretty good at a 5.0, which was an yellow-orange color and that means fishes are able to live in our tank. Since our nitrate result was fine we didn't have to clean our tank again.  But in order to fix the ammonia problem, we did have to add some bacteria into the water. We did add bacteria to fix the ammonia and our tank is pretty clear as of today.




(ours was a little lighter)

Tuesday 4/3

My plan for my aquarium is to have a certain number of fish (right now we have 4) with my partners Catie and Bailey.  The types of fish we have is a Neon Tetra and a Black Neon Tetra. We chose these organisms because they work well in groups of five or more and are suitable to the temperature of the water. With some fish the water either has to be colder or have a water heater or else the fish could die.

The Neon Tetra is a pelagic freshwater fish native to tropical parts of northern South America. The Neon tetra originates from western Brazil, south-eastern Colombia and eastern Peru and wild Neon Tetras can be found in the headwaters of the River Amazon, Tiger, Napo and Yarapa.

The Back Neon Tetra is a native to the Paraguay basin of southern Brazil.
