Pomacentrus

Pomacentrus alleni

(Burgess, 1981)

Andaman Damsel, Allen’s Damsel, Neon Damsel

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Eastern Indian Ocean: Similan Islands off northwestern Thailand.

Size: 3 inches (6 cm)

Natural Environment: Inhabits areas of rubble on outer reef slopes at depths between 10 to about 50 feet (3 – 15 m) and feeds on zooplankton, benthic invertebrates and algae.

General Husbandry: One of the more attractive and commonly seen in the trade species in this genus, having a neon blue body with a yellow anal fin, and black on the lower tail lobe, and a partly black dorsal fin.

Best maintained in small groups of at least five to seven members and non-aggressive tankmates.

As to diet, will eat most regular aquarium foods, e.g., live fortified brine shrimp and/or finely chopped various frozen or fresh meaty foods such as mysis, squid, fish flesh, shrimp, clam, etc., and plant material, e.g., flake foods, especially those containing Spirulina and offered once or twice daily.

Taxonomy:

    Order: Perciformes

    Suborder: Labroidei

    Family: Pomacentridae

    Subfamily: Pomacentrinae

    Genus: Pomacentrus

FYI: Even though quite passive and will ignore other fish in the aquarium, larger aquariums, e.g., 50 gallons and above for this species, provide far more openness for small shoals to ‘peacefully’ coexist.

If maintained in groups of less than mentioned above, they tend to be over dominate of each other and may force some members into hiding. The bigger the group, the less intergroup picking on each other exists.

Often a poor shipper.
