+1...and agrees, except for clowns, Damsels are WAY AGGRESSIVE and I think you will find them to be a problem later! Even clowns can be territorial but at least they won't chase down everything in your tank. Well, unless you get a tomato clown. I had one a loooong time ago for a few days. Watched him terrorize my other fish and got rid of him quick! It's too bad damsels are like that. The blue ones have a beautiful color!
