About
The Javanese or bluestreak damselfish (Neoglyphidodon oxyodon) occurs in the Indo-Australian Archipelago, including the Philippines and Indonesia, and at Ashmore Reef in the Timor Sea (FishBase). It is also known under the former name Paraglyphidodon oxyodon. It reaches 15 cm TL. Juveniles are dark with thin neon-blue lines and a single white bar across the middle, but as they grow the lines and bar fade and adults become dark brown to black. It lives in the shallows, within a few metres of the surface, on current-swept lagoon reef flats, feeding on algae and benthic invertebrates. Eggs are laid on rock and guarded by the male. In Japan it is sold as "neon damsel", whereas Neon damselfish is the English name of Pomacentrus coelestis, so the names are easily confused. It is easy to feed but becomes very aggressive with age; Saltcorner advises one per tank with robust tankmates. It does not harm corals. The neon-blue juveniles are popular and regularly available.
