Blue Grosbeak

The orbiculate cardinalfish, chubby cardinal, or polka-dot cardinalfish (Sphaeramia orbicularis)^[1] is a species of Apogonidae (cardinalfishes). It grows to about 10 cm total length, and has a thin, dark vertical 'waistband' with scattered dark spots toward the tail. It is found in coastal areas throughout much of the Indo-Pacific, including off East Africa, Kiribati, the Ryukyu Islands, New Caledonia, Belau, and the eastern Caroline and Mariana Islands.^[1]

The male incubates the eggs until they hatch.^[1] It eats mostly planktonic crustaceans, mainly at night.^[1] It is not a common marine aquarium fish.^[2]
