Origin[edit | edit source]

Found along mainstream Amazon River in Peru, Colombia, and Brazil, including lower parts of the Putumayo, Trombetas, Negro, and Xingu rivers; lower Tocantins and Capim rivers; Branco River (Amazonas basin) in Brazil and Guyana, and the Essequibo River in Guyana.[1]

Sexing[edit | edit source]

Males have longer finnage and are more vibrant in colour.

Tank compatibility[edit | edit source]

This fish can be aggressive and is quite territorial so should either be in a species tank in male/female pairs or with similar sized robust fish.

Diet[edit | edit source]

Will accept most foods including Cichlid pellets and flake as well as live/frozen food such as bloodworm and shrimp.

Feeding regime[edit | edit source]

Feed once or twice a day.

Environment specifics[edit | edit source]

Must have a soft substrate as this fish will dig, and therefore any décor needs to be secure so it can't fall and injure the fish.

Behaviour[edit | edit source]

A territorial Cichlid.

Identification[edit | edit source]

An attractive Cichlid with an oval body shape and lateral compression. It has a pointed snout, rounded caudal fin and pointed dorsal and anal fins. The dorsal, caudal and anal fins has extended rays, more evident in males, giving it their common name. It is pale in colour with iridescent scales in blue, red and silver, they have a darker spot into the middle of their flanks on either side.
