ok i want to make an ecosphere(for those of you who dont know what that is, its a self contained ecosystem that requires no care except for proper lighting) ive seen them at brookstone with shrimp in them but i wanna go a step further and add fish. the problem is that i need fish that will be able to survive and multiply slowly in a small place(i was thinking zebra danios or guppys) but then i need something to keep the population down like a top predator so it doesnt get out of hand and they all die cause that would be bad. but hen i also need something to keep the pradator in check so it doesnt kill them all. i would also add some shrimp, snails, assort. amphipods and plants. and the container would be like either a very large glass jar or i was thinking maybe a 10gal water jug but the container has to be air tight so if you guys could help with some ideas for all of this stuff then please let me know…its more of an experiment than a pet
tell me something if they dont eat how come they last anywhere from 2-10 years
im not saying the shrimp lived for 2-10 years im saying the ecosphere has lasted that long and its only 10 years because the first one that was ever created had started 10 years ago. also if you knew alot about fish tanks you would know that bacteria grows in the gravel which breaks down ammonia into nitrites and nirtates which the plant takes in along with co2. you know earth doesnt have a filter right?
granted there may not be enough bacteria or plantlife to do this successfuly but obviously its working pretty well. and i didnt say i wanted to buy one i wanted to make one… maybe you should look into something a little more before you judge me on what i KNOW(there ill put in some caps so i look special)
i know all of that i mean it was just an idea anyway i guess i wont do it cause i dont wanna kill anything and i already have a 2 fish tanks i just wanted to see how something could take care of itself and how the animals grew and multiplied and stuff like that
