Geographical Origin and Habitat: Native to the Southwestern Pacific Ocean, primarily found along the Great Barrier Reef of Australia, Middleton Reef, and Lord Howe Island. Inhabits shallow reefs down to 25 meters.

Taxonomy and Morphology: Member of the family Pomacentridae. Oval and compressed body shape. Reaches a maximum standard length of 7 cm. Sleek fin profile.

Social Behavior: Highly social, shoaling species. Forms large schools that active swim above branching corals, utilizing them as protection from predators.

Coloration and Sexual Dimorphism: Distinctive coloration split diagonally by a dark brown stripe extending from the eye to the dorsal fin. Golden-yellow upper body, silvery-white lower body. No obvious dimorphism.

Aquarium Setup: Requires a minimum tank size of 100 liters with plenty of open swimming space and structured rockwork for shelter.

Diet and Feeding: Omnivorous diet. Provide high-quality small flakes, pellets, frozen daphnia, cyclops, and brine shrimp to maintain vitality.

Water Quality: Maintain stable reef conditions: temperature 22-26 °C, pH 8.1-8.4, and salinity 1.020-1.025 with strong water circulation.

Compatibility and Cohabitation: Highly compatible with other peaceful reef-safe fishes. Must be kept in a group of at least 6 individuals to foster natural behavior.

Aquarium Breeding: Oviparous. Spawns adhesive eggs on rocky surfaces or algae. The male assumes the role of guarding and fanning the clutch until hatching.

Risks and Diseases: Hardy and active species. Ensure regular water changes and efficient filtration to prevent the accumulation of dissolved organic wastes.
