Bicolor Cleaner Wrasse (Labroides bicolor) Care Guide
Labroides bicolor is an Indo-Pacific cleaner wrasse that feeds on the ectoparasites of other fish; its specialized diet makes it difficult to maintain.
Compiled by Aquairi from published sources · Published · Updated
Overview
Labroides bicolor is a cleaner wrasse of the Indo-Pacific, reaching about 15 cm in total length. Like others in the genus Labroides, it removes ectoparasites and mucus from larger fish at established cleaning stations. The two-tone coloration gives it its common name.
Taxonomy
- Family: Labridae
- Genus: Labroides
- Scientific name: Labroides bicolor
- Common synonyms: Bicolor Cleaner Wrasse
Habitat
The species is widespread in the Indo-Pacific, from East Africa to the Line, Marquesan and Society islands, north to southern Japan and south to Lord Howe Island. It is reef-associated, occurring from the surface to about 40 m, typically between 2 and 20 m. Juveniles are solitary and secretive in caves, while adults range widely seeking client fish.
Tank requirements
- Minimum tank volume: 300 L (79 gal)
- Temperature: 24-26 °C (75-79 °F)
- pH: 8.1-8.4
- Specific gravity: typical marine range
- Lifespan: 8-15 years
Diet
Labroides bicolor is a carnivore that feeds by removing crustacean ectoparasites and mucus from other fish. This specialized cleaning diet is difficult to replicate in captivity, which is why the species is considered demanding and best left to experienced keepers.
Compatibility
It is a peaceful, mid-water fish that coexists with a wide range of tank mates, since it services rather than competes with them. Robust community fish are suitable companions, while highly aggressive species that may harass it should be avoided.
Breeding
The species is oviparous and shows distinct pairing during breeding. As in the genus Labroides, individuals are protogynous, with a dominant female able to change sex to male.
Conservation status
IUCN Red List: Least Concern (assessed 2009). It is collected for the aquarium trade.
Bicolor Cleaner Wrasse Breeding Guide (Labroides bicolor)
Overview
The bicolor cleaner wrasse (Labroides bicolor) belongs to the cleaner-wrasse genus Labroides, native to the Indian and Pacific Oceans. Like the rest of the genus it is a cleaner fish, removing ectoparasites from larger client fish at fixed cleaning stations. It carries a two-tone yellow-and-blue pattern and shares the demanding dietary needs of its close relatives.
Sexing
Cleaner wrasses of the genus Labroides are protogynous hermaphrodites that live in harems controlled by a dominant male. Documented for the genus, when the dominant male disappears one of the larger females changes sex to take over the territory. Sex therefore tracks social rank, and a fixed visual sex marker for an individual is not reliable.
Spawning Behavior & Trigger
Cleaner wrasses maintain cleaning stations and pair from within the harem to spawn. As oviparous reef wrasses they are pelagic broadcast spawners, releasing gametes into the water column so fertilised eggs drift away as plankton. No captive spawning trigger is documented for this species.
Egg & Fry Care
Fertilised eggs are pelagic and hatch into planktonic larvae dispersing in open water. This larval phase is the central barrier to captive rearing, and there is no home-aquarium fry-rearing protocol for the species.
Common Challenges
The overriding obstacle is diet: cleaner wrasses feed on ectoparasites and mucus from client fish and often fail to accept substitute foods, so many individuals starve in aquaria. This specialised feeding, combined with harem social structure and pelagic larvae, makes both long-term keeping and breeding impractical, and the species remains wild-caught.
