Eight-banded Butterflyfish

Geographical Origin and Habitat: Tropical Indo-Pacific, distributed from India and Sri Lanka to the Philippines and Solomon Islands. Inhabits silty or sheltered reefs rich in Acropora corals.

Taxonomy and Morphology: Member of the family Chaetodontidae. The specific name is directly derived from the eight prominent vertical black bars that cross its body.

Social Behavior: Shy and highly specialized species. Usually found in small groups or singly, sheltering within branching coral colonies and feeding on polyps.

Coloration and Sexual Dimorphism: Cream-white to pale yellow body. Marked by eight thin, evenly spaced vertical black bands on the head and sides. The fins have fine black margins.

Aquarium Setup: Requires a large, specialized reef-style aquarium of at least 250 liters containing extensive branching or table Acropora coral colonies.

Diet and Feeding: Obligate corallivore, feeding exclusively on Acropora polyps. Almost impossible to keep in home aquariums unless fed live corals or successfully trained.

Water Quality: Demands pristine marine conditions: temperature 22-27 °C, pH 8.1-8.4, salinity 1.020-1.025 with zero organic waste, strong skimming, and high water flow.

Compatibility and Cohabitation: Highly peaceful. Not reef safe. Best housed in large fish-only systems with robust, non-competing tankmates.

Aquarium Breeding: Reproduction in home aquariums is undocumented. Spawns pelagic eggs, and larvae spend weeks drifting in open ocean currents before settling.

Risks and Diseases: Very high risk of starvation in captivity. Recommended only for public aquaria or expert hobbyists capable of providing live corals for food.
