A slender neon blue fish with a blending of yellow or orange near the bottom of the body down to and including the anal fin. Its tail is more elongated than most damselfish. This fish can be found in the Indian and Pacific Oceans and the Great Barrier Reef. It is named after Dr. Gerald Allen, an ichthyologist who is recognized as the world's foremost authority on damselfish.
Size: ave. 3/4" to 1 1/2"; can get up to 4"
No. in Tank: One
Tank: min. 30 gallons
Food: (Omnivore) Needs a varied diet including meaty items (frozen mysid shrimp, raw shrimp and silversides), herbivore preparations and vegetables. Offer enriched foods to enhance and/or keep its colors from fading. Feed small amounts (what it can eat in 3 to 5 minutes), 2 to 3 times a day. Thaw frozen items before feeding to this fish.
Adaptation: Needs a lot of hiding places and plenty of open space in which to swim. It will take 2+ hours to fully acclimate.
Compatibility: Ideal for a reef system as it will not harm most invertebrates and corals. Needs other semi-aggressive/aggressive fish as tank-mates. As this fish matures, it will pick on weaker fish while leaving other fish alone. Do not place with any peaceful, docile fish.
