Species description

Geographical Origin and Habitat: Western Atlantic Ocean: North Carolina to Brazil, in deep reef environments.

Taxonomy and Morphology: A member of the Labridae family, it features a slender, laterally compressed body design. Adults reach a maximum size of approximately 7.5 cm.

Social Behavior: Shows a highly active and peaceful behavior. Dominant males may display minor intraspecific territoriality during breeding parading.

Coloration and Sexual Dimorphism: The coloration is exceptionally vivid, characteristic of reef-dwelling wrasses. Sexual dimorphism is prominent, with males showing brighter colors.

Care, breeding and tankmates

Aquarium Setup: Requires a tank of at least 150.0 liters with plenty of live rock shelters. A tight-fitting lid is mandatory to prevent jumping out.

Diet and Feeding: Carnivore. Feed zooplankton, frozen foods like mysis and brine shrimp, alongside high-quality marine pellets.

Water Quality: Reef parameters with pH 8.1-8.4, gravity 1.023-1.025, and low nitrates are critical.

Compatibility and Cohabitation: Peaceful reef companion. Suitable for community tanks. Keep only one male per aquarium to avoid fighting.

Aquarium Breeding: Egg scatterer. Protogynous hermaphrodite. Spawning in private aquaria has not been documented successfully.

Risks and Diseases: High risk of jumping. Prone to skin damage if stressed by aggressive tankmates. Maintain stable water conditions.
