Blackspot Cleaner Wrasse Breeding Guide (Labroides pectoralis)
Labroides pectoralis is an Indo-Pacific cleaner wrasse with a parasite-based cleaning diet and pelagic spawning; it is not home-bred, and this guide documents its real reproductive biology and care difficulty.
Overview
The blackspot cleaner wrasse (Labroides pectoralis) is one of the cleaner wrasses of the genus Labroides, native to the Indian and Pacific Oceans, distinguished by a black spot at the base of the pectoral fin. Like its congeners it is a cleaner fish that services larger client fish at cleaning stations and shares the genus's demanding feeding requirements.
Sexing
Cleaner wrasses of the genus Labroides are protogynous hermaphrodites living in harems controlled by a dominant male; when that male is lost, one of the larger females changes sex to take over the territory. Sex therefore follows 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 that 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 principal obstacle is the parasite-and-mucus cleaning diet, which many individuals do not replace with substitute foods, leading to starvation in captivity. Together with the harem social structure and the pelagic larval phase, this rules out home breeding, and the species remains wild-caught.
