Overview
Chrysiptera hemicyanea is a species in the family Pomacentridae. A dazzling small damselfish with an electric blue upper body that transitions to a vivid yellow-orange belly. One of the less aggressive damsels, though it can still be territorial in small tanks. Hardy and disease-resistant, making it an excellent starter marine fish. Readily accepts all prepared foods.
Taxonomy

Azure Damselfish Breeding Guide
Overview
Reproduction of Chrysiptera hemicyanea is not well studied at the species level, but it has been successfully bred in captivity to increase supply to the aquarium trade and reduce wild collection. The species reaches about 7 cm and follows the reproductive pattern of its genus.
Breeding Setup
Members of the genus Chrysiptera form mating pairs and follow a benthic egg-laying life cycle, with eggs adhered to a substrate. The breeding setup therefore provides a flat, defensible spawning surface such as rock or hard substrate within an established pair's territory. The genus has a comparatively short larval stage relative to other damselfish, and its population can double in about 15 months.
Spawning Behavior & Trigger
Spawning follows the genus pattern: a pair deposits adhesive eggs onto the prepared substrate. As damselfish can be territorial in small tanks, giving the pair its own defended area supports settled spawning.
Egg & Fry Care
Within the genus the male stays at the nest to guard and aerate the eggs until they hatch. The relatively short larval stage is an advantage for captive rearing compared with many other damselfish, though larvae still require small planktonic live foods during the pelagic phase.
Common Challenges
Because species-specific spawning data are limited, breeders rely on the general genus behavior. Damsel territoriality means tankmates must be chosen carefully, and the larval phase still demands suitably small live food and clean, stable water.
