Giant moray (Gymnothorax javanicus) at the pampering parlour. 😉
Bluestreak cleaner wrasse (Labroides dimidiatus), are usually found at cleaning stations. When visitors like the giant moray come near the cleaning stations, the cleaner wrasses greet the visitors by performing a dance-like motion in which they move their rear up and down.
The visitors are referred to as “clients”. Bluestreak cleaner wrasses clean to consume ectoparasites on client fish for food. The bigger fish recognizes them as cleaner fish because they have a lateral stripe along the length of their bodies, and by their movement patterns.
Cleaner wrasses greet visitors in an effort to secure the food source and cleaning opportunity with the client. Upon recognizing the cleaner and successfully soliciting its attention, the client fish adopts a species-specific pose to allow the cleaner access to its body surface, gills and sometimes mouth.
