Distribution

Endemic to the rio Xingu basin where it inhabits a section of the river's main channel known as 'Volta Grande do rio Xingu' which lies between Belo Monte falls…

Habitat

Occurs predominantly in whitewater rapids with young specimens observed to congregate under flat rocks at the bottom of shallow stretches whereas adults are fo…

Aquarium size

Given the adult size an aquarium with base dimensions of 120 ∗ 45 cm or equivalent should be the smallest considered for long-term maintenance.

Maintenance

Not difficult to maintain under the correct conditions but largely unsuitable for the 'general' community aquarium. We recommend keeping it in a set-up designe…

Water conditions

Temperature: 27 – 32 °C; this species will not thrive in cooler water. pH: 6.0 – 8.0 Hardness: 3 – 15 dGH

Diet

Gut analyses of wild specimens revealed the diet to be composed chiefly of algae, particularly diatoms and filamentous genera such as Spirogyra alongside small…

Behaviour and compatibility

Juveniles are relatively peaceful but males in particular become highly intolerant of conspecifics as they age and typically aggressive towards any other fish …

Sexual dimorphism

Adult males develop a broader, slightly flatter head profile and longer pectoral-fin spines than females.

Reproduction

Fish traded as L081 have been bred on a single occasion. Any successful attempt is likely to depend on providing a large tank, well-oxygenated water and an exc…

Notes

Prior to description this species was traded under the DATZ code numbers L018, L085, or L177, and 'Das Aquarium' code LDA060, while a very similar-looking fish…
