Geographical Origin and Habitat: Western Indian Ocean: Comoro Islands and eastern coast of Mozambique. Inhabits coral reefs, rocky crevices, and shallow caves at depths between 1 and 25 meters.

Taxonomy and Morphology: Belongs to the family Pseudochromidae, genus Pseudochromis. Features a slender, flexible body, large eyes, and a mouth with small sharp teeth. Grows to 7.0 cm.

Social Behavior: Territorial and bold, highly defensive of its chosen cave. Can be aggressive toward fish of similar shape or size.

Coloration and Sexual Dimorphism: Named after its iridescent stripes that taper off toward the posterior body. Males are typically larger and may exhibit more intense coloration, particularly when breeding.

Aquarium Setup: Requires a tank of at least 80.0 liters with plenty of live rock arranged to create numerous caves and dark tunnels. A tight-fitting lid is recommended.

Diet and Feeding: Carnivorous. Feeds on small crustaceans and worms. Provide a variety of frozen foods such as mysis, brine shrimp, and high-quality protein pellets.

Water Quality: Maintain stable marine conditions: temperature 22.0-26.0 °C, pH 8.1-8.4, specific gravity 1.020-1.025.

Compatibility and Cohabitation: May behave aggressively toward small ornamental shrimps, tubeworms, and passive fish. Best kept singly without other dottybacks.

Aquarium Breeding: Protogynous hermaphrodite. Lays spherical egg masses inside a cave, which are actively guarded and aerated by the male.

Risks and Diseases: Very hardy and disease-resistant. However, severe territorial fights can lead to secondary bacterial infections.
