Care
Blue Line Damsels are relatively easy to care for due to their adaptability and resilience. They thrive in well-established aquariums with plenty of rockwork and hiding spaces. It's important to maintain stable water conditions and provide a varied diet of meaty foods, algae, and quality marine flake or pellet foods to keep them healthy and retain their vivid coloration.
Reproduction
Like many damselfish, the Blue Line Damsel is an oviparous species, with females laying eggs that are then fertilized by the male. The male typically guards the eggs until they hatch. Breeding them in captivity can be challenging but rewarding for dedicated hobbyists.
Habitat
Chrysiptera caeruleolineata is native to the Western Pacific, where it is commonly found in shallow reefs and lagoons. They prefer areas with abundant coral and rock formations that provide shelter and feeding opportunities.
