Black Leopard Wrasse

Geographical Origin and Habitat: Found in the Western Pacific, from the Philippines and Indonesia to the Solomon Islands and the Great Barrier Reef. Inhabits coral-rich reef slopes and sandy patches down to 30 meters.

Taxonomy and Morphology: Belongs to the family Labridae. Features a laterally compressed body and small mouth. Reaches a maximum length of 12 cm.

Social Behavior: Peaceful, timid, and strictly diurnal. Grazes constantly near the substrate. Instantly dives into the sand bed when threatened.

Coloration and Sexual Dimorphism: Body color is black or dark brown, covered with numerous small yellow or white spots. Spawning males display iridescent green and red markings on their heads.

Aquarium Setup: Demands an aquarium of at least 200 liters with plenty of live rock and a deep (7-8 cm) fine sand bed. Coarse gravel must be avoided as it injures the fish. A secure lid is required.

Diet and Feeding: Carnivorous. Feeds on micro-crustaceans. Needs an established tank with a healthy copepod population. Supplement with frozen foods 3-4 times daily.

Water Quality: Keep standard marine parameters stable: temperature 23-27 °C, pH 8.1-8.4, salinity SG 1.020-1.025. Strong filtration and skimming are highly recommended.

Compatibility and Cohabitation: 100% reef safe. Best kept with quiet, non-aggressive species. Bold, territorial tankmates will keep this fish buried and stressed.

Aquarium Breeding: Protogynous hermaphrodite. Broadcast spawners with pelagic larvae. Captive spawning has not been successfully reared in home aquariums.

Risks and Diseases: Starvation is a primary concern during acclimation. Susceptible to marine ich (Cryptocaryon) if subjected to stress or poor water conditions.
