Male Bettas an be kept with most species of community fish. The most common tankmates are Pygmy Corys, White Cloud Mountain Minnows, Harlequin Rasboras and even African Dwarf frogs. Given the size of the tank though, tankmates would not be recommended. Most community fish do best in small schools which would overcrowd a 2.5 gallon tank.
