Personally, I would put 3-4 small fish in your tank. Clowns, gobies (any), firefish, small wrasse, small dwarf angel (coral beauty, flame, fireball, cherub), royal gramma, cardinals, damsels (some ppl like em), chromis (nice color under high light), small blenny (bicolor or midas), pseudochromis, or a small hawkfish. You have a large range of small fish to choose from.
