The Cleaner Wrasse (Labroides dimidiatus) is recommended for experienced hobbyists only. It needs meaty foods several times a day, as their small bodies can't subsist off one meal per day. If you can get past that initial hurdle, it can be trained to eat dry foods like flake or pellet food. They are called cleaners because they often will set up a Cleaning Station for fish to approach, and then get a once over by the wrasse. It seeks out parasites and dead tissue, and will even enter the mouths and gills from amenable fish.
Wish me luck!
