The Cleaner Wrasse - Helping to Keep Fish Parasite Free, Belize Barrier Reef
The best known cleaner fish species, the bluestreak Indo-Pacific in a non- human model happens in the cleaner-client mutualism between fish. Advertising dance (1), Bluestreak cleaner wrasse Labroides dimidiatus, Losey ( ) Cleaner fish Labroides dimidiatus manipulate client reef fish by. Cleaning behaviour is deemed a mutualism, however the benefit of On Atlantic and Indo-Pacific coral reefs, cleaner fishes interact with many client fish species [ 5]–. (d) sites on reefs with cleaner wrasse Labroides dimidiatus present . rapid worldwide depletion through human exploitation –. Still other species have symbiotic relationships with other fish, a relationship in The cleaner wrasse, one of species of wrasse, is found along coral reefs.
However, the temptation to cheat is extremely high because from the gleaning of client mucus, cleaners get additional calories and essential amino acids Eckes et al. This predisposition to eat client derived mucus seems to be less evident in Caribbean cleaning gobies and in most of the facultative cleaners, which also defect by eating client derived scales and some mucus, but do not seem to prefer to do so Soares et al.
Moreover, cleaners adjust their behavior in accordance to client value parasite infestation and mucus quality and choice options whether clients have access to one or more cleaning stations; Soares et al.
Consequently, cleaners use this information to decide how often, whom they should bite under and which circumstances, as to achieve contextual benefits and attract key clientele to be inspected Bshary and Grutter, Memory and Learning Cleaner interactions with clients are extremely frequent, with the same individual clients visiting cleaning stations several times each day.

For instance, cleaner wrasses L. The level of socio-environment complexity seems to underlie the cognitive background of these animals for instance, their learning abilities, see Wismer et al.
The provision of physical contact is a costly investment on behalf of cleaners, as they refrain from eating during its provision. Clients on the other hand, benefit from receiving tactile stimulation as it lowers baseline and acute stress levels i. Hence, cleaners use the provision of tactile stimulation as a mean of negotiation for the occurrence and duration of cleaning interactions with clients.

Bonding Cleaners establish privileged relationships with conspecific partners that contribute to their behavioral variation. Cleaners are sometimes found alone which happens only for females, in the case of L.
In the case of the cleaner wrasses L. This fish is responsible for setting up what are known as "cleaning stations," providing a valuable service to other fish by picking off and "cleaning" its customers of parasites and dead tissue.

The wrasse, in turn, receives nutrients from the parasites and tissue. The parasites that the wrasse consume are organisms that live on or within the body of a host, in this case a fish.
Often, parasites are simply small crustaceans that live between the scales of fish and feed on its tissue. It is not known whether these critters, which are a fact of life for many fish, are anything more than an annoyance, but it is clear that most fish prefer to have them removed.
For this removal, many fish turn to the cleaner wrasse to get the job done. Reef Brief is a weekly column published in the San Pedro Sun The cleaner wrasse, one of species of wrasse, is found along coral reefs worldwide and usually choose a home along the reef that is popular among fish to set up its cleaning station.
At this location, various fish literally line up and wait to be "cleaned" by the wrasse. This is one of the few cases in which varying species of fish actually inhabit the same space without becoming territorial or aggressive with each other.
It's clear that these fish have one thing on their mind when they line up at the cleaning station: Easily distinguished by a bright blue and yellow band, the cleaner wrasse makes an effort to advertise its services by performing a dance.
Likewise, when a fish wants to be "cleaned" it sends specific signals to the wrasse, such as keeping its body stationary, while spreading its fins and gills and opening its mouth.
