I had to do this I just remembered.. even dug out the paper.
Found out I packed the jar FULLLLL of plants, added some cheap fish and for the most part the goldfish ate organisms on the plants. Not gonna lie I sneaked them some food if I remember correctly. It was a lot of fun but it was hard!

Yeah, it might work for a while with snails or shrimp but I dont see it working with fish :( How long do you have too keep the fish in there? I actually had a friend a few years back who's mom had an Ecospehere. Dont know if he still has it but when I saw it he told me he had it for a few months. and there were little shrimp inside it. it was pretty neat.
He said it has to last all semester, which means until January! AH! Okay definetly will do tons of plants, and add probably 2 snails I'm thinking (they are baby size). I really appreciate all the help, if you keep thinking of stuff I would love to hear it! Thanks for the links too, I'll be doing all the research I can!
