I had my betta in a community tank with tetras for a while. Food didn't seem to be a problem for my guy, but the occassional fin nipping sessions from the tetras were. I had to move him into a 20 gallon tank with corys.harried_mom said:I've been considering adding a betta to my community tank, but I'm concerned that my tetras are too speedy and he wouldn't get enough food. Is this concern valid?
