I've been looking to make an aquascape for a while now, but fish was always optional for me. I just want to know if any fish would do well in a 5 gallon or 7 gallon. If not, I won't add fish. Just plants. But if anyone names one, I will do as much research as I can. I don't want to seem as one of those people who just go to the pet store and buy a betta and keeps it in a rum bottle. If anyone suggests I don't keep a fish in the tank, I won't. I want the tank for the plants.
