From what I've learned there are Rainbow species (Bosemans) that are actually aggressive with other males if they don't have enough space to avoid each other and swim etc. Apparently they really need a large tank (55 gal min.) to have enough room. I just discovered the Dwarf Rainbow, which is smaller and is very peaceful and not aggressive.

Good luck. If they continue to chase and harrass each other and other fish, you will end up with dead fish likely from stress.

Looks like Glossolepis incisus. Males do get aggressive especially during spawning time. They do not fare well in overstocked or small tanks. How big is the tank? I'm afraid your only option is get it out of the tank before it harasses all your tetras and minnows to death.

odd never had a bow bother another fish that wasn't a bow. Mine seem to do fine in their crowded tank, but its mainly them that are taking up all that room. I agree that 55 gall is min. for the larger bows that get 3" or bigger. I would not put my boesemani in anything smaller. These are fast active fish. Its not that they are aggressive at all IMO.

I am 80% sure the fish in your pics is male, females are generally drab in color therefor not seen in chain petstores much at all.
