Neon Damsel Fish - Pomacentrus alleni - Allen's Damselfish
The Neon Damselfish is also known as Allen's Pomacentrus and the Allen’s Demselfish. It was named after Dr. Gerald Allen, the icthyologist who is recognized as the world's authority on damselfishes. This slender fish is neon blue with a blending of yellow near the bottom of the body down into the anal fin. The Neon Damselfish is a brightly colored beauty that can make a dramatic addition to many saltwater aquariums.
The Neon Damselfish species is nearly ubiquitous on both protected and exposed reefs in moderately clear water from below the surge zone to at least 30 m. It is a solitary inhabitant of areas of mixed coral and rock or rubble and feeds on filamentous algae, small invertebrates, and fishes. Its coloration is variable, ranging from dark blue to tan.
This brilliant species is a moderately common inhabitant of isolated coral heads and patches of rubble on sandy lagoon and channel floors from 1.5 to at least 12 m. It occurs in small groups, generally remains within 1 m of shelter, and feeds on zooplankton and filamentous algae.
The Neon Damselfish can be kept in temperatures between 72 and 78 degrees. The pH should be 8.4, with specific gravity between 1.020 and 1.025 unless there are invertebrates in the aquarium in which case the lower limit should be 1.022. Water quality should remain high.
General Size Specifications: The Neon Damselfish grows up to 8 inches. The small size will come to you generally 1 to 3 inches; the medium generally 1 to 3 inches; the large generally 1 to 3 inches. Most Neon Damselfish reach lengths of two inches (seven centimeters). The lower edges of their tails have black streaking. The rest of the fish is a beautiful bright blue hue, save the tail and the underside of the fish, which are golden.
In the wild, Neon Damselfish seem to prefer outer reef areas with clear water. They seem to do best when kept by themselves in captivity, though they form large schools in the wild. The Neon Damselfish are often noted in areas of current, whether it is a strong pull or gentle wave motion. Neon Damselfish usually remain in depths between 1 and 12 meters.

Minimum Tank Size: The Neon Damselfish is a semi-aggressive fish that requires a 30 gallon or larger aquarium to hide and swim.
Habitat: The Neon Damselfish are relatively hardy. They are most commonly collected from the Indian Ocean, though they range from the Pacific Ocean to southeastern Asia, particularly in the area of the Andaman Sea.
Feeding and Diet: The Neon Damselfish diet should include a variety of meaty foods, herbivore preparations, and flaked foods. Most Neon Damselfish can be maintained nicely on flake foods, supplemented with protein and vegetable items.
Breeding: The Neon Damselfish are relatively difficult to breed. Allen's Damsel Fish spawn on the undersides of rocks. Parents will guard the eggs until they hatch, usually for several days.
