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.

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 & Heliofungia actiniformis.

<span class="mw-page-title-main">False cleanerfish</span> Species of fish

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 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.

A cleaning station is a location where aquatic life congregate to be cleaned by smaller creatures. Such stations exist in both freshwater and marine environments, and are used by animals including fish, sea turtles and hippos.

Cleaner shrimp Species of crustacean

Cleaner shrimp is a common name for a number of swimming decapod crustaceans, that clean other organisms of parasites. They belong to any of three families, Hippolytidae, Palaemonidae, and Stenopodidae . The last of these families is more closely related to lobsters and crabs than it is to the remaining families. The term "cleaner shrimp" is sometimes used more specifically for the family Hippolytidae and the genus Lysmata.

Cleaner fish 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.

Bluestreak cleaner wrasse Species of fish

The bluestreak cleaner wrasse, Labroides dimidiatus, is one of several species of cleaner wrasses found on coral reefs from Eastern Africa and the Red Sea to French Polynesia. Like other cleaner wrasses, it eats parasites and dead tissue off larger fishes' skin in a mutualistic relationship that provides food and protection for the wrasse, and considerable health benefits for the other fishes.

<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.

Cleaning symbiosis Mutually beneficial association between individuals of two species

Cleaning symbiosis is a mutually beneficial association between individuals of two species, where one removes and eats parasites and other materials from the surface of the other. Cleaning symbiosis is well-known among marine fish, where some small species of cleaner fish, notably wrasses but also species in other genera, are specialised to feed almost exclusively by cleaning larger fish and other marine animals. Other cleaning symbioses exist between birds and mammals, and in other groups.
