cardinal fish

The Orbiculate cardinalfish, Sphaeramia orbicularis is a species of cardinalfish. It grows to about 10 centimeters 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 East Africa, Kiribati, the Ryukyu Islands, New Caledonia, Belau, and the eastern Caroline and Mariana Islands. The male incubates the eggs until they hatch. It eats mostly planktonic crustaceans, mainly at night. While it is not a common marine aquarium fish, it can be a good for beginners.
