Halichoeres cyanocephalus
Family: Labridae ยท Wrasses
Also known as: Yellow-Cheek Wrasse, Yellowcheeked Wrasse, Blue-Head Yellow-Cheek Wrasse
The Yellowcheek Wrasse is a charming small Halichoeres species that displays bright yellow patches on its cheeks contrasting with a blue-green head and a lighter body with subtle markings. This attractive color combination, along with its small size and peaceful nature, makes it an ideal wrasse for community reef aquariums of modest size.
In the wild, Yellowcheek Wrasses inhabit coral-rich reef areas where they actively forage for small invertebrates among the rubble and sand. Like other Halichoeres species, they are effective pest controllers that will hunt and consume flatworms, pyramidellid snails, bristleworms, and other nuisance invertebrates that commonly appear in reef aquariums. This biological pest control is a significant practical benefit that adds functional value beyond their ornamental appeal.
The Yellowcheek Wrasse is one of the easier wrasses to maintain in captivity. It accepts prepared foods readily, adapts quickly to aquarium life, and is resistant to common marine diseases. Its small adult size means it can thrive in tanks as small as 55 gallons, making it accessible to a wide range of aquarists. It is peaceful, reef-safe, and an excellent addition to any community reef setup.
Yellowcheek Wrasses are carnivores that feed on small invertebrates found on reef surfaces and in the sand. In captivity, they eagerly accept frozen mysis shrimp, brine shrimp, chopped seafood, marine pellets, and flake food. They actively hunt aquarium pests including flatworms and bristleworms. Typically begin feeding on the first day in captivity. Feed two to three times daily.
The Yellowcheek Wrasse is peaceful and compatible with virtually all community reef fish. It coexists well with clownfish, tangs, blennies, gobies, and other peaceful species. It will consume small pest invertebrates but does not harm corals, clams, or ornamental shrimp. May occasionally spar with other small Halichoeres wrasses. An excellent beginner-friendly community reef fish.
Check CompatibilityYellowcheek Wrasses are protogynous hermaphrodites. Males develop more vivid coloration. Spawning occurs in the water column with pelagic eggs. Captive breeding has not been achieved. All specimens in the trade are wild-caught from the Western Pacific.
