Apogon

Apogon margaritophorus

(Bleeker, 1854)

Redstripe Cardinalfish, Pearly Cardinalfish

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Western Central Pacific Ocean: Malaysia to Solomon Islands.

Size: 3 inches (7 cm)

Natural Environment: Inhabits seagrass beds in sheltered lagoons and hides near long-spine urchins. Usually found at depths between 3 – 15 feet (1 – 5 m) where it feeds on small fishes and crustaceans/zooplankton during evening hours.

General Husbandry: Occasionally seen in the trade and this very hardy and quite nice looking species has a pearly colored body with two red horizontal stripes and several shorter brownish bars.

Best maintained fish-only aquariums with subdued lighting, yet can also be maintained in reef aquariums, with both having several rocky caves/hiding areas. If maintained with moderately aggressive tankmates, will remain in hiding during daylight hours and may not get its fair share of the food when the aquarium is fed. If maintained with peaceful tankmates, will spend a good portion of its time in the aquarium open areas.

As to diet, products such as marine fish and crustacean flesh, clams, and other marine meaty foods should be enriched and finely chopped and fed several times daily. Depending upon the environment in which its maintained, the best time of the day to feed are early morning and evening hours.
