abstract
Forty-one species of 20 families of fishes were observed being cleaned at Bonaire by two species of decapod crustaceans and four species of fishes. Of 525 observations of fishes being cleaned (clients), over 60% involved species of the Serranidae, Scaridae and one species of Pomacentridae (Chromis multilineata). Gobies (Gobiosoma spp.) and Pederson's cleaner shrimp (Periclimenes pedersoni) were the most frequent cleaners of all three groups of clients. Only P. pedersoni performed a display that may have attracted clients. Cleaner species except Thalassoma bifasciatum cleaned the mouth and gills of clients, as well as the rest of the body. Clients approached cleaners, presented part of their body to the cleaner, opened their mouth or flared their gills, remained relatively motionless, and then twitched their tail and body and swam away. Unlike other clients, species of the Serranidae rarely assumed a vertical posture during cleaning. Chromis spp. and Clepticus parrai formed tight ball-like formations around cleaners. The behaviour of cleaner fishes and shrimp at Bonaire was more similar to that reported for eastern Pacific species than that of Labroides spp. of the Indo-Pacific area. 1998 Taylor & Francis Group, LLC.
