gobies, cardinals, chromies, perchance a dfft style tang (kole is an excellent recommendation, gorgeous fish and fairly well tempered).
Maybe some (1 or 2) jawfish? (I like them poking out from underneath the rocks..so cool to watch em building their dens)
I've successfully added a couple firefish and scissortail gobies to my 90 reef with no probs whatsoever (was afraid they'd get squimish about similiar body types) and they make a good presentation as 'stationary' fish along side the couple cardinals.. looks good with a couple clowns and a tang..
gl on your choices
