Description

Labroides dimidiatus reaches a maximum size of about 12 cm. Its body is elongated and laterally compressed, with a characteristic coloration: a horizontal black stripe on a light blue to white background, and a bright yellow tail. The fins are translucent with bluish reflections. It is a very active diurnal fish, known for its mutualistic cleaning behavior. Sexual dimorphism is slight: males are slightly larger and more colorful than females, and individuals can change sex (protogyny).

Care notes

A tank of at least 200 liters is recommended, with stable water parameters (temperature 24-28°C, pH 8.1-8.4, salinity 1.020-1.025). A rocky setup with hiding places is essential. This fish is a strict carnivore: it must be fed several times a day with small meaty foods (brine shrimp, mysis, chopped krill). It is compatible with most reef fish, but can be aggressive towards other cleaner wrasses. Caution: it may starve if the aquarium does not have enough client fish or if the diet is inadequate. It is sensitive to water quality fluctuations.
