Native range
Captive hybrid of unresolved Heros parentage; no defensible wild native range can be assigned.
Natural habitat
Use a large warm South-American-cichlid style setup with wood/rock structure, open swimming room, efficient filtration and low-to-moderate current.
Diet & feeding
Feed a varied omnivorous cichlid diet with substantial plant matter alongside quality pellets and occasional invertebrate foods.
Breeding & sexing
Research-backed guidance for identifying sexes and reproductive behaviour.
Sexing
Hybrid parentage makes visual sexing less dependable; breeding tubes and confirmed spawning behaviour are more reliable than colour or pattern.
Breeding
If fertile, typical Heros-style biparental substrate spawning is expected, but hybrid fertility and behaviour cannot be guaranteed without parentage.
