Although he has a good point it is an aggressive fish but with that lineup I wouldn't really worry. My brother has 2 blue, 1 yellow tail,1 domino,a 3 stripe, a banghai cardinal,yellow tang,ocellaris and tomato clown in a 36 bow with no problem. I think it's a lil too much fish for that tank but it works and the damsels were the 1st ones in the tank.
