Can I add another?

I have a 29 g tank, established for 6 months or so. About 40lbs of live rock and shallow sand bed, aqua c remora skimmer, 3 powerheads. Current inhabitants are a flame hawk, lawnmower blenny, maroon clown, and a coral banded shrimp. We had a very small six line wrasse, but we went away for a weekend and upon our return, found it in the CBS's mouth. That was several months ago, and I'd like to get another small fish that will add some color besides red. I know this may cause problems with the clown, who was added last. He's still very small, and hasn't shown any aggression toward anything in the tank.

So, any thoughts? Would an additional fish need to be peaceful, or semi-aggressive to match the clown? Suggestions? Thanks.

How about a neon goby? They are small and great for setting up cleaning stations to groom your fish. However, I'd watch the Hawkfish when adding any smaller fish since he/she was added first.
