The Azure Damselfish (Chrysiptera hemicyanea) is a small marine (saltwater) fish in the Pomacentridae family of damselfish. It is also known as the Azure Demoiselle, Yellow-Dipped Damsel, Half-Blue Damsel, and Royal Demoiselle.
The Azure Damselfish is electric blue and yellowish-gold. It has yellow on its tail fin and bottom fin, as well as along the lower part of its body.
It grows to about 7 centimetres (2-3 inches) long.
It is native to the tropical waters of the Indian Ocean and the Pacific Ocean (the Indo-Pacific region). It prefers shallow coral reefs and sheltered lagoons. It is benthic because it lives mostly on the bottom of the ocean.
It feeds on plankton, algae, and small crustaceans, such as crabs and shrimp.
It is often found alone or in pairs.
It is territorial, defending its territory from other fish. A male will look after the eggs of several females – often up to 10,000 eggs in his territory. Each female lays around 300 eggs. The eggs hatch after about 4 days. The male looks after the young fish, called fry.
