Uaru amphiacanthoides

Adults have a conspicuous large black triangular flank patch.

Markings change markedly from juvenile to adult stages; these are not different species.

Needs warm, clean, thoroughly filtered water. Fry feed on the parents' skin mucus, but this is not their only possible food.

Social behaviour and territory

Prefers groups outside breeding. A group of 6–8 can pair naturally; both parents care for the young.

Has a high requirement for plant-based foods, complemented by moderate amounts of other foods. Plants in planted tanks are often eaten.
