Ok. It has a few pieces of live rock and a little hang on back filter and a heater. Maybe I'll put the barletts in there because she's small and I wanna keep the ignitus together and I don't wanna put the lemon peel in there. He's kinda big and wouldn't have much room to swim. I guess at first I'll keep all five in there. And then test the water everyday for a week and see if the water levels ever get bad and then move a fish and do a water change if it does get bad.
