Multispine Damsel

Neoglyphidodon polyacanthus

Neoglyphidodon polyacanthus, known as the Multispine Damsel, is a damselfish found in the western Pacific Ocean. This species is commonly seen in the aquarium trade due to its distinct coloration and manageable size. Juveniles are easily recognizable by their bright yellow bodies adorned with blue lines extending from the eye to an eyespot, a feature that fades as they mature into grayish-black adults. They can grow up to 12 centimeters in length. The Multispine Damsel inhabits coral reefs, particularly around the southern Great Barrier Reef, Lord Howe Island, and New Caledonia. They are typically found at depths ranging from 2 to 30 meters, with a preference for deeper surge channels on the leeward side of reefs. These fish are non-migratory and tend to dwell outside lagoons as adults, while juveniles may be found within them. In terms of reproduction, Neoglyphidodon polyacanthus is oviparous, with males taking on the role of guarding and aerating the demersal eggs that adhere to the substrate. This species is diurnal and exhibits distinct pairing during breeding. The IUCN lists the Multispine Damsel as Least Concern.
