I would not suggest Glofish in a 5 Gal. They are a Schooling / Shoaling fish and you need 5 fish Minimum. You could maybe get away with 5 in a 10Gal with frequesnt water changes but do not go smaller and what ever you do do not get the Glo Barbs...Hi! I haven't been on here for awhile, but still love fish! We currently just have a 30 gallon tank stocked with Angel fish, Neon Tetras, various danios, and an algae eater (I think he's a pleco).
I am thinking about getting a five gallon tank for my boys' room. Of course it is probably more for me than it is for them, but was wondering what I could stock it with. I would hate to buy a five gallon and only put a betta in it. Not that is anything wrong with bettas, I'd just like some active swimmers. Youngest boy wants some Glofish, would they be okay in a five gallon? Also wondered about putting some harlequin rasboras in a five gallon.
