Hawaiian cleaner wrasse are small blue and yellow fish that clean the mucus, dead tissue and parasites off other fish. They establish permanent stations on the reef, and fish that need cleaning swim up and hover around until it’s their turn.
A fish can get nipped during a cleaning, but they also seem to enjoy the process and the sensation of the cleaner wrasse dragging its fins over a client’s body – a one-stop clean and massage. This bullethead parrotfish seemed positively ecstatic during its clean, several times sporting a look of bliss on its face.
Maybe next time I’m in the water, I’ll dive down and give it a go.
