“Juvenile Black Cardinalfish exhibit a white, almost translucent posterior half with a pitch black anterior half. As they mature the white color recedes to only the unpaired fins. Finally as mature adults, they lose any trace of white color and range from dark mocha to pitch black depending on their mood. This species also exhibits ocelli or eyespots at the base of the second dorsal and anal fins.
Black Cardinalfish are paternal mouthbrooders and lay very large spawns. Unlike the Banggai Cardinal the tiny larvae are released from the mouth immediately upon hatching. Their maximum size is 4.5” and they are fairly peaceful with other reef fishes. They may be kept singly or in a group. Only during spawning will females become somewhat combative with others of the same species. ORA Black Cardinalfish eat a variety of frozen and pellet foods however hobbyists may wish to avoid housing them with small crustaceans that they may see as food.”
