Native range
South America: parts of the Paraná-Paraguay system and Amazon tributaries including Guaporé, Madre de Dios, Mamoré, Jamari and Tapajós drainages.
Natural habitat
Shallow streams, pools and quiet margins, often close to vegetation over sand or mud. Provide tall plants/wood, open midwater space and gentle circulation.
Diet & feeding
Generalist feeder; use quality cichlid pellets/flakes with frozen/live invertebrates and some plant matter.
Breeding & sexing
Research-backed guidance for identifying sexes and reproductive behaviour.
Sexing
Sexual dimorphism is subtle. Mature males may be larger with slightly more extended fins; a bonded spawning pair is the most reliable practical indicator.
Breeding
Biparental substrate spawner, often using a vertical or inclined leaf/wood/stone surface; parents defend eggs and fry.
