@rogue.beauty: The small purple and gold fish is a Hawaiian cleaner wrasse, and you can see it doing some cleaning on a very happy moray eel! @savannah timmer caught this when we were hanging out at the end of Kewalo pipe - Hawaiian cleaner wrasses have an essential job on the reef. They host cleaning stations and signal to their “customers” that they are open for business by darting around erratically until fish and turtles gather to be cleaned. Fish signal their willingness to be cleaned by becoming near motionless, spreading their fins, and opening their gill covers. The cleaner wrasse has a specially designed mouth that allows it to remove external parasites, mucus, and dead skin cells from the host’s body. The cleaner wrasse will even enter the mouth and gill chambers of larger fish and eels #hawaii #fishfacts #scubadiving
