I have 2 male guppies in a tank with 2 platy, 2 cories, and a few snails and the 2 guppies are bullying each other. Or rather, 1 guppy is bullying the other. He's not injuring him but he is being a bully.

Is this normal behavior? I thought male guppies were the way to go if you didn't want babies?

Yeah, I think this is pretty normal behavior in male guppies. They tend to harass similar sized fish. If you have a few females per male then the males will direct their attentions to the females instead of finding someone to bully.

Is the bullied one still getting enough food?
