Species description
Geographical Origin and Habitat: Western Indian Ocean, endemic to the coral reefs of Sri Lanka. Typically found in shallow waters and reef areas rich in hiding places.
Taxonomy and Morphology: Belongs to the family Pseudochromidae. Characterized by a body structure adapted to its active lifestyle, showing bright coloration. Size up to 7.5 cm.
Social Behavior: Active species with a aggressive temperament. Shows moderate to high territorial habits depending on sex and population density.
Coloration and Sexual Dimorphism: Males and females display visible differences in color pattern and vibrancy, especially during the courtship phase.
Care, breeding and tankmates
Aquarium Setup: Requires a marine tank of at least 26 gallons (approx. 100.0 liters), decorated with live rocks to provide natural shelter. For sand-dwelling wrasses, a fine sand bed of at least 2-3 inches (5-8 cm) is essential.
Diet and Feeding: Carnivorous. Feeds on amphipods, copepods, and meaty frozen foods (mysis). It is recommended to feed the fish two or three times daily in small portions.
Water Quality: Stable parameters: temperature 23.0-27.0°C, pH 8.1-8.4, SG stable between 1.020 and 1.025. Monitored nitrates and phosphates.
Compatibility and Cohabitation: Compatible with reef fish. Avoid housing with larger predators or highly aggressive tankmates.
Aquarium Breeding: Oviparous species. Eggs are deposited in small protected spaces and guarded by the male. Not bred in captivity.
Risks and Diseases: Sensitive to transport stress and high jump risk; requires a tightly fitted aquarium lid.
