I have a 55 gal semi-aggresive tank. I would like to get a fish that is active. I have a giant danio that is always swimming so what else is active like him.
Any other ideas? I was thinking mabey a ID shark? I wanted a fish that will grow to a good size. And yes I know ID sharks get huge but when it gets to big I would trade him in.
uh, how about a rainbow shark. they stay decent size and have good personality. Plus, if its a semi-aggressive tank, it wont matter much if the one you picked out has an attitude problem
