I knew the clown tang was aggressive and my stocklist other than him are: 1 false perc, 1 maroon clown, 1 scooter blennie, 1 lawnmower blennie, 1 pajama cardinal, 1 bangaii cardinal, and 3 damsels. I don't really have many fish and don't plan on adding many more. I am just concerned about controlling the growth of my macro's. It sounds like I will have to pruin some back for a little while but as the clown gets bigger he will probably keep up with the growth.
