You might want to also get a royal gamma or one of the very colorful reef safe wrasses. Most of these fish stay small...about 4 inches or so.
In my 65 gallon I have two damsels, a flame angel, a bicolor blenny, a blueside fairy wrasse and a sixline wrasse. My new wrasse is also know as a velvet multicolor wrasse. He is so cool....His head is a hot fushia pink fading to a purple behind the gills. His body color is a royal blue on the underside with an orange mixed with purple in the middle of his body and orange and blue on his dorsal fin. Really unusual. Get a male if you get a wrasse as they have more color than the females. My new bicolor blenny has a really cute personality. He watches your every move from his hole in his rock and is a lot of fun to watch. Lesley
