60 Gallon Stocking

So far in my 60 gallon, for fish, I have 2 clownfish, 1 yellow tang, 1 damsel, 2 cardinals, and 1 diamond goby. For invertebrates and corals, I have 4 turbo snails, 2 peppermint shrimp, 1 cleaner shrimp, 1 brittle starfish, branching green star polyps, plusing polyps, and 2 small anemones. I would really like to add one or two more fish to add more color, but I'm not sure if this is to much. If not, what would be some colorful fish to add?
