Mesonauta guyanae

Sexing

 * These fish are quite difficult to visually sex. The pectoral and anal fins of mature males will be slightly more elongated, but this is not a definite way of sexing them.

Tank compatibility

 * A shy Cichlid that is generally peaceful and does well housed with similar-sized peaceful fish. Should not be housed with small fish such as Neon Tetras as they will be eaten. Can be kept in pairs and with other generally peaceful American Cichlids such as Angelfish and German Blue Rams.

Diet

 * Does well fed on a meaty diet including daphnia and brine shrimp as well as pellet and flake food. They will also willingly accept and benefit from vegetarian foods including pellet and flake and may nibble blanched vegetables.

Feeding regime

 * Feed once or twice a day.

Environment Specifics

 * These fish should be in a spacious tank with good filtration and well aerated but not too strong a current. They must be provided with plenty of hiding places in plants and bogwood. They are quite sensitive to nitrates, so nitrites to water quality must be kept immaculate.

Behaviour

 * A shy and timid American Cichlid.

Identification

 * An oval-shaped fish with a pointed snout very easily mistaken for the more common Festivum. Was imported as a Festivum in the 1950s and 60s. There are three known variations, two being "Rio Cobra" and "Rio Tapajos".
