For my 29 gallon with 22 pounds of lr I would like a coral beauty, percula clown, and my damsel that i already have. Don't worry, he's harmless. Do you think this would be ok or could I add another small fish like a blenny or goby. I like bi color blennies and lawnmower blennies but I think the lawnmower would get to big. It is a mature tank with plent of algae to go around. Also, do bi colors eat hair algae? Anything I should know? Does this sound like a godd list? TIA
