Fish Fanatic
From my experience I've found Rainbow Sharks and Albino Rainbow Sharks to be fairly communal. They will establish a territory in your tank and chase away any fish that venture in there but they do not have big enough mouths to bite anything of a reasonable size.
However I would stay clear of Redtail Black Sharks (just a red anal fin) as these get to about 10" and are more aggressive.
But as long as you just keep one Rainbow shark in your tank you should be ok.
