Good thinking Andy. Consider also a Yellow Tail Damsel. Unlike other Damsels, that eventually just SUCK, Yellowtails are calm, gentle tankmates usually. They hide and dart in and out of the rockwork. I have one with a Maroon clown in a 29 and he's a favorite.
LT1, please refrain from making those kind of suggestions to people trying to get started on the right foot. A stocking like you described in anything less than a 200g tank is destined for catastrophe. The clowns will soon be chow, the trigger will destrot any and all cleaning crews, the lion will soon be so big you won't be able to get a hand in the tank and the wrasse, well, you said it best, "That Dragon has evil in its eyes.."
Suggesting any of those fish, with the exception of the clowns IF he didn't already have a clown, is irresponsible..
