Also known as the Polka-dot Cardinalfish, the Spotted Cardinalfish, the Coral Cardinalfish, Pajama Cardinal, and the Red Spotted Cardinal, this is one popular saltwater aquarium fish. The Pajama Cardinal comes from the Indo- Pacific. It has two distinctive dorsal fins, typical of cardinalfish. The name “cardinal” refers to the fact that many of this species are red, although yellow and silver are probably more predominate colors. The Pajama Cardinal has a green / yellow face and a dark band running from the first dorsal fin to the pectoral fin. The back half of the body is silver, with red/orange dots, giving it the appearance of polka-dot pajamas. The fins at the back half of the body are fringed in white. Pajama Cardinals are nocturnal and therefore have very large eyes.
