Blue streak cleaner wrasse (Labroides dimidiatus)

Blue streak cleaner wrasse. Amazing and strange fish of the sea at your fingertips.
Available in: 
MEERESMUSEUM Stralsund

Small sanitary blue streak cleaner wrasses feed on parasites of other fishes. They are known as common cleaner fish that set up cleaning stations and attract larger fish to their stations to get cleaned. Large predators like moray eels, groupers or barracudas, are their “patients”, as well. The larger fish not only refrain from devouring these small cleaner fish, but actually readily open their mouths and gill cavities so that they are able to clean. The majority of wrasses are hermaphrodites, i.e. they carry male and female gonads simultaneously. This is characteristic of all haremic species, when a well-defined social group of fish consists of one dominant male and multiple females. When the male dies or leaves (the group), the most dominant female replaces it, i.e. the female wrasse radically changes its colours and behaviour and takes over the male’s functions. When darkness sets in, blue streak cleaner wrasses burrow into the sand on the floor and produce a mucous envelope where they remain until sunrise.
