Don't they just sit there, suspended in the water? If so, I'd suggest 3 blue/green chromis that'll school. Hardy too. Also, IMO
you need something that's sit on the rocks too. Maybe a bi-color blenny which'll nibble algea too. A midas blenny is bigger and swims out front too, but perches on the rocks and like to peek out to watch things. Also, I see you don't have a sand dweller on your list. Algae blenny, watchman goby, and others may give you some choices for sand dwellers.
Also, try xenia, hammer, and frogspwan corals to give you more variety. They're pretty easy too. Of course the xenia can go wild, but you can trim it and sell it back to the LFS
Do all of your current fish have to go in this tank? If not, I'd also recommend a pair of clowns.
