The Hawaiian cleaner wrasse or golden cleaner wrasse (Labroides phthirophagus), is a species of wrasse (genus Labroides ) found in the waters surrounding the Hawaiian Islands. The fish is endemic to Hawaii. These cleaner fish inhabit coral reefs, setting up a territory referred to as a cleaning station. They obtain a diet of small crustacean parasites by removing them from other reef fish in a cleaning symbiosis. [3]

Description

The Hawaiian cleaner wrasse grows to a maximum length of about 12 cm (5 in). [4] This fish is strikingly coloured; the anterior part is golden, with a dark lateral stripe running from the eye to the tail, becoming wider at the back. The posterior part of the fish has purple and violet colouration on the fins. [5]

Distribution and habitat

This fish is endemic to the Hawaiian Islands and nearby Johnston Atoll. It is typically found on coral and rocky reefs, but avoids the surge zone. It is found at depths down to about 90 m (300 ft). [1]

Ecology

The Hawaiian cleaner wrasse moves with a graceful flitting movement. At night it may rest in a balloon-like cocoon it builds from mucus. The species is monogamous, with a pair bond being formed during the breeding season. [4] It is an obligate feeder on the ectoparasites of other fish to the extent that it will fail to thrive in an aquarium where these feeding needs are not met. [1]

The behaviour of this fish is very similar to that of the closely related bluestreak cleaner wrasse (Labroides dimidiatus), widely found in the rest of Indo-Pacific region. Both species operate cleaning stations where larger fish (clients) visit and cooperate in the removal by the cleaner fish of their ectoparasites, loose flakes of skin and mucus. The arrangement is mutually beneficial, with the client fish having its parasites removed and the wrasse gaining protection and finding an easy meal. The process is not without danger for the cleaner fish as many of the client fish are piscivores, but observations in the wild show an apparent absence of "cheating" by the client fish, which seem to appreciate the tactile stimulation provided by the cleaner fish moving around their skin and fins. [6]

It seems that cleaner fish build up a relationship with their clients and there is some communication between them. When the client arrives at a cleaning station, it observes what the cleaner fish is doing, if it already has a client, of the cleaner's previous client "jolts" (twitches in response to a cleaner "cheating" by taking a bite of the client's scales or mucus [7] ), in which case the prospective client may depart. If happy with what it sees, the client adopts a certain species-specific pose which invites the cleaner fish to set to work on it. [6]

Status

This fish has a restricted range in the vicinity of the Hawaiian Islands but is relatively common there. Much of its range is within the Papahānaumokuākea Marine National Monument, a well-managed marine protected area. No specific threats to this fish have been identified although degradation of its coral reef habitat is likely to have some impact on it. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern. [1]

Aquatic Trade

This fish is sometimes taken out of the wild for aquarium trade around the world. It can be found on many aquatic fish websites.

<span class="mw-page-title-main">Wrasse</span> Family of marine fishes

The wrasses are a family, Labridae, of marine fish, many of which are brightly colored. The family is large and diverse, with over 600 species in 81 genera, which are divided into 9 subgroups or tribes. They are typically small, most of them less than 20 cm (7.9 in) long, although the largest, the humphead wrasse, can measure up to 2.5 m (8.2 ft). They are efficient carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing. Juveniles of some representatives of the genera Bodianus, Epibulus, Cirrhilabrus, Oxycheilinus, and Paracheilinus hide among the tentacles of the free-living mushroom corals and Heliofungia actiniformis.

The false cleanerfish is a species of combtooth blenny, a mimic that copies both the dance and appearance of Labroides dimidiatus, a similarly colored species of cleaner wrasse. It likely mimics that species to avoid predation, as well as to occasionally bite the fins of its victims rather than consume parasites. Most veiled attacks occur on juvenile fish, as adults that have been attacked in the past may avoid or even attack A. taeniatus.

<i>Thalassoma bifasciatum</i> Species of fish

Thalassoma bifasciatum, the bluehead, bluehead wrasse or blue-headed wrasse, is a species of marine ray-finned fish, a wrasse from the family Labridae. It is native to the coral reefs of the tropical waters of the western Atlantic Ocean. Individuals are small and rarely live longer than two years. They form large schools over the reef and are important cleaner fish in the reefs they inhabit.

Cheating is a term used in behavioral ecology and ethology to describe behavior whereby organisms receive a benefit at the cost of other organisms. Cheating is common in many mutualistic and altruistic relationships. A cheater is an individual who does not cooperate but can potentially gain the benefit from others cooperating. Cheaters are also those who selfishly use common resources to maximize their individual fitness at the expense of a group. Natural selection favors cheating, but there are mechanisms to regulate it. The stress gradient hypothesis states that facilitation, cooperation or mutualism should be more common in stressful environments, while cheating, competition or parasitism are common in benign environments.

<span class="mw-page-title-main">Cleaner fish</span> Fish that remove parasites and dead tissue from other species

Cleaner fish are fish that show a specialist feeding strategy by providing a service to other species, referred to as clients, by removing dead skin, ectoparasites, and infected tissue from the surface or gill chambers. This example of cleaning symbiosis represents mutualism and cooperation behaviour, an ecological interaction that benefits both parties involved. However, the cleaner fish may consume mucus or tissue, thus creating a form of parasitism called cheating. The client animals are typically fish of a different species, but can also be aquatic reptiles, mammals, or octopuses. A wide variety of fish including wrasse, cichlids, catfish, pipefish, lumpsuckers, and gobies display cleaning behaviors across the globe in fresh, brackish, and marine waters but specifically concentrated in the tropics due to high parasite density. Similar behaviour is found in other groups of animals, such as cleaner shrimps.

<i>Elacatinus</i> Genus of fishes

Elacatinus is a genus of small marine gobies, often known collectively as the neon gobies. Although only one species, E. oceanops, is technically the "neon goby", because of their similar appearance, other members of the genus are generally labeled neon gobies, as well. Except for a single East Pacific species, all reside in warmer parts of the West Atlantic, including the Caribbean and Gulf of Mexico. They are known for engaging in symbiosis with other marine creatures by providing them cleaning service that consists of getting rid of ectoparasites on their bodies. In return, Elacatinus species obtain their primary source of food, ectoparasites.

<i>Elacatinus puncticulatus</i> Species of fish

Elacatinus puncticulatus is a species of goby from the eastern central Pacific Ocean, where it is found on reefs from the Gulf of California to Ecuador. This species occurs at depths ranging from 1 to 21m, and usually in association with the sea urchin Eucidaris thouarsii. The size of the goby varies depending on sex, with females being typically smaller than males, and their geographical location as well as their role as a cleaner goby also has impacts on their morphology. Due to their bright coloration and lack of aggression, the species is commonly found in the aquarium trade.
