Allen's Damselfish

(Pomacentrus alleni)

Pomacentrus Damselfish should be added to well established aquariums with plenty of room to swim. Plenty of rock work with caves and crevices should be provided for grazing and hiding. Pomacentrus Damselfish may pick at benthic invertebrates. A diet of meaty and algae based foods which include Spirulina should be provided several times daily. Groups of juveniles can be added to larger aquariums however, careful consideration will need to be given before adding to the aquarium as Pomacentrus Damselfish become more aggressive and territorial to fish of the same genus or size as they mature. Most Pomacentrus Damselfish are hard to differentiate between males and females however, males are generally larger. Some Damselfish may also change colors as they mature.

The Allen's Damselfish are also known as the Andaman or Neon Damselfish. Commonly seen in the aquarium trade. The Allen's Damselfish is one of the more beautiful of the Damselfish. They have a neon blue body, yellow anal fin, partly black dorsal and lower tail lobe. They can grow to a little over 3".

We recommend a minimum aquarium size of 30 gallons or larger for this species.
