[quote=zpeck30;584915]i recently bought a fish at my lfs the tag said assorted rainbow fish so i got one i belive it my be australian but im not sure heres two picture there real blurry but the best i could get.. the first few days he was fine but as of tonight hes been chasing and nipping at my red tetras and rosey red minows..both are about 2 inches and the rainbows about 2 and a half..will this fin nipping continue?if i get more will they school and become worse or less agressive?e]
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.
