Lots of great reef safe (vs. invertebrate safe) wrasses out there. I know Brian has some as does Seahorse and CnC. It depends a bit on what you are looking for. The flashers are quite attractive and stay relatively small but can be a bit skittish. Lots of very attractive fairy wrasses (solar, clown, velvet, pink margin, rhomboid) which will get a bit bigger but also seem more outgoing. If you want something that is good "pest" control, you can go with things like leopards (many versions) or possum wrasses although these both can be a bit more reclusive - at least until they are well settled. The more "confident" species like Coris and Melanarus are great hunters but will also get larger and potentially go after your hermits and snails so something to keep in mind. Personally, I would go after something in the fairy wrasses as long as your tank is covered (they are jumpers by nature).
