Relevant Information:

In the original description it was stated as Brazil, Est. Pará, tributary of Rio Tapajós but was later corrected by Nijssen & Isbrücker to Rio Jauna (= R. Juma) at Trans-Amazonica highway, about 6º09'S, 59º55'W, tributary of Rio Aripuaña, Amazonas, Brazil. Aquarium Care: This is akin to most of this genus, very peaceful, and would be best housed with small to medium sized tankmates such as Tetras, Rasboras and Danios or in a species tank for breeding purposes. Best to purchase 6 individuals or more as they will be happier in a group. Diet: Readily accepts a mixed and varied diet which includes granular foods, tablet food, frozen bloodworm and good quality flake to name but a few. Remarks: Not imported very often and is quite rare in the hobby.

Common Name:







South America: Brazil; tributary of Rio Aripuana, Rio Madeira basin.
