Multi Spine Damsefish

(Neoglyphidodon polyacanthus)

Neoglyphidodon Damselfish should be added to well established aquariums with plenty of room to swim. Plenty of rock work should be provided for grazing. Neoglyphidodon Damselfish are very aggressive careful planning and consideration should be taken before adding fish to aquariums. They should be housed singly and only be housed with larger, intrusive and more aggressive tank mates. A diet of meaty and algae based foods which includes Spirulina should be provided several times daily. They may also pick at soft corals. May see juvenile and adult color differences.

The Multi Spine Damselfish are also known as the Red One Spot Damselfish. Rarely seen in the aquarium trade. The Multi Spine Damselfish juveniles and adults will have color differences. Juveniles are a brilliant yellow with a black eye spot trimmed with blue, blue white line above the eye running to the false eye spot and a small white and black spot on the caudal peduncle. As the fish matures they begin to darken to a dark blue and lose most of their yellow coloration, however some yellow may still be seen on its belly. They can grow a little over 6".

We recommend a minimum aquarium size of 50 gallons or larger for this species.
