I need some help from all you people who know fish inside and out! I currently have a 58 gallon with a pair of Amphiprion ocellaris clowns, a bi color blenny, and a shrimp/shrimp goby combo. I am thinking about picking up a pair of black ocellaris clowns for the same tank. Would that be too much, and would it be a battle royal between any of the fish?!?!?!??
