Just a thought here, I would stay away from the Maroon Clown fish, they can get kinda big. The one I had at one time, would do a number on the sand bed I had in the tank also. I bought 3 of the regular Fire fish for my old tank, figured they would pretty cool, and they did for awhile. I eventually ended with only one, I read later that the more dominant one will some times kill the others, don't know if that's what happend, just knew they ended up dead.
