features
The fish have an elongated body and are 15 to 16 cm (males) or a maximum of 12.5 cm (females) long. They are silvery, the belly is white. A black band begins at the throat and extends over the belly to the lower tip of the caudal fin. On the sides of the body and on the dorsal and anal fin, the males show several blue iridescent , horizontal bands. Their dorsal fin is brownish. At the beginning of the dorsal fin base there is a dark brown spot. The fins of the males are pointed, while those of the females are slightly rounded. The mouth of Cardiopharynx schoutedeni is terminal. The jaws are covered with two to three rows of teeth that are close together. The jaw teeth are three-pointed in young fish and conical in older fish. The teeth of the outer row of teeth are bent back. The pharyngeal teeth are thin and close together in a heart-shaped arrangement ( etymology : Gr .: "kardias" = heart + pharynx = cardiopharynx ). The caudal fin is forked. The intestine is three and a half times as long as the fish.

Way of life
Cardiopharynx schoutedeni is a semi-pelagic plankton eater that forms schools of several hundred fish. They move at depths of at least 3 to 15 meters over sandy and muddy bottoms and snap at small invertebrates, e.g. B. after copepods or rummage through the ground and sift out microorganisms such as diatoms , other unicellular algae and bacteria with their gill rakes . The fish are mouthbrooders . A clutch contains about 60 eggs, which are 4 mm in diameter.
