Care
Chrysiptera rex is a relatively easy fish to care for. It requires an aquarium with plenty of rockwork and hiding spaces to feel secure. This species is known for being territorial, so it's important to provide ample space to prevent aggression, especially if housing multiple individuals or with other damselfish species. A varied diet of meaty foods, algae, and high-quality marine flake or pellet food will help maintain their health and coloration.
Reproduction
In the wild, Regal Demoiselles are oviparous, with distinct pairing during breeding. Males prepare and guard nesting sites where females lay eggs. The male then protects the eggs until they hatch. In the aquarium, breeding can occur, but raising the fry can be challenging due to their small size and specific dietary needs.
Habitat
The natural habitat of the Regal Demoiselle includes coral reefs and lagoons in the Western Pacific, from the Philippines to Australia. They are typically found at depths ranging from shallow waters to about 30 meters. In the aquarium, simulating their natural environment with live rock and stable water conditions is beneficial for their well-being.
