Sphaeramia

Sphaeramia orbicularis

(Cuvier, 1828)

Orbiculate Cardinalfish

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: East Africa to Kiribati, north to Southern Japan, south to New Caledonia, Belau to eastern Caroline and Mariana Islands.

Size: 4 inches (10 cm)

Natural Environment: Inhabits shallow coastal lagoons and often seen in mangrove areas. Usually found at depths between 3 – 50 feet (1 – 15 m) where it feeds on crustaceans/zooplankton during evening hours.

General Husbandry: Somewhat common in the trade with this hardy species having a silvery face and body with a central body vertical mottled black band, and the aft body dotted with dark spots.

Best maintained in 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, this slow moving fish 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.
