What sort of clown is this?

My two perc. clowns try to bite me all the time! You would think after I've been the only one feeding them for 4 years they would be nicer. When I am trying to glue a new frag in the tank I litterally have to push these guys out of the way, they have no fear of my hands in the tank. I used to have a maroon clown with them but he was a bit of a bully but the percs always got him back. As soon as the maroon's back was turned they would dart out and nip him in the butt and then rush back into the rocks! It's easy to see where the name "clown fish" comes from with their antics.
