I have a small bowl (about a quart) that is currently empty except for some java moss growing on a small piece of driftwood. I would appreciate any suggestions/ comments you may have of fish to put in there. The space is just enough for a fully grown male betta. This bowl has no lid nor heater and is a Marineland Betta Sphere in case anyone wants to know. The fish listed above in the poll are just ideas i have thought of so far and would like any input on other fish that would be compatible in this evironment. Thanks for your suggestions.
