They aren't that hard to keep levels stable. I had no problems in my fw and have had none so far in my sw just keep steady in the water changes. It will be fine in there, they hardly swim at all, just hop from rock to rock.Oh I know, people will holler and moan about a fish in three gallons but oh well, I think I can give it a good life in there. Heck I could do 50% water changes twice a week and it wouldn't be a big deal eather! At college I will have my own freezer so I will be able to keep frozen brine shrimp, daphnia, mysis, bloods, plankton, and various others so it can have a good diet.
I have a hammer in hand debating on to smash it or not :edit:..not the tank!!! the rock!!
