Pseudanthias

Pseudanthias parvirostris

(Randall & Lubbock, 1981)

Sunset Anthias, Diadem Anthias, Shortsnout Anthias

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: Maldives to Solomon Islands and Japan south to Australia.

Size: 3 inches (7 cm)

Natural Environment: Inhabits coastal and outer reef slopes and usually found in small groups at depths between 150 to about 200 feet (45 – 60 m) where it feeds on zooplankton.

General Husbandry: Rarely seen in the trade, and a species with many different color combinations. Sometimes the male is a yellowish pink with red along the upper body and into the central portion of the tail. Females are sometimes overall yellow.

Best maintained in dimly lit aquariums as this is usually a deep-water collected species, along with some rocky caves and strong water movement that has a large unencumbered area for schooling in small groups. Tankmates should be peaceful species and those that perfer low light aquariums, and all tankmates should be the last to enter the aquarium.

If maintained in brightly lit reef aquariums, will be extremely shy, difficult to feed, with the acclimation timeframe lengthy, maybe not achievable.

As to diet, will eat most regular aquarium foods, e.g., finely chopped various frozen or fresh meaty foods such as mysis, squid, fish flesh, shrimp, clam, etc., and should be offered at least twice daily and dispensed upstream so water currents carry food to their location.

Sometimes difficult to get feeding, and if so, fortified live adult brine shrimp may be necessary until they accept other types of aquarium foods, e.g., frozen foods and fresh marine fish and invertebrate flesh.

Taxonomy:

    Order: Perciformes

    Suborder: Percoidei

    Family: Serranidae

    Subfamily: Anthiinae

    Genus: Pseudanthias

FYI: Must be maintained in small groups, with only one male and several females.

Can jump out of the aquarium, therefore some sort of cover may be necessary.
