Neoglyphidodon nigroris, (Cuvier, 1830)
Neoglyphidodon nigroris, commonly known as the black-and-gold chromis or Behn's damsel, is a species of damselfish found in the Indo-West Pacific. It occasionally makes its way into the aquarium trade.
Adults can grow up to 13 cm (5.1 in) in total length. There are two coloration varieties in adults: individuals ranging from the Andaman Sea to Japan are black, while individuals from the western Pacific Ocean have a tan front and a yellow rear. The latter variety may deserve species status under the name N. xanthurus, and the two varieties overlap around the island of Bali. Juveniles are yellow with 2 longitudinal black stripes and a black spot at the pectoral-fin base.
This species of damselfish is found throughout the Indo-Pacific region. In the Indian Ocean, it is found around Sri Lanka, the Andaman Sea, Indonesia, and Australia. In the Pacific Ocean, it is found around Indonesia, the Philippines, Australia, Vietnam, Japan, Malaysia, the Solomon Islands, Vanuatu, and Hawaii. It lives in coral reefs and lagoons rich in corals, and is found at depths of 2–21 m (6.6–68.9 ft).
This species is omnivorous, feeding mainly on algae, crustaceans, tunicates, and salps.
During breeding, the female lays her eggs (which are demersal) on substrate. The male then guards them and aerates them until they hatch.
