diadema basslet ?

[gman52]

I got a new diadema basslet today and put him in the tank. I already have one occlearis clownfish in the tank. But now the two are fighting. The basslet will poke his head out of the rocks and the clownfish will dart after him. it doesnt seem to be getting better. The clownfish swims around the rocks looking for him. It looks like the basslet is instigating it, by sticking his head out of holes going back in, and sticking his head out again. The clowns anal fins seem to be a little shredded. Is there a chance they will stop fighting, how long until they stop fighting, or am i gonna have to get rid of the basslet.
thanks

IMO, it's risky to add a basslet...they can be quite aggressive; especially if they take up a spot too close to a clown. Clowns can also be somewhat aggressive/territorial.
I don't want your clown to get hurt.
