<I>Labroides bicolor</I> (IMAGE) Rice University Caption Two Labroides bicolor cleaner fish with their 'client' partner. L. bicolor helps its client by feeding on parasites, but it also takes an occasional bite of client flesh. A review of current literature found the behavior could not be called cheating because it was unclear whether client fish are harmed by the biting or whether the occasional bite of client flesh provides a measureable 'fitness increase' for L. biocolor.
