Overview
A peaceful schooling fish for softwater communities; keep six or more with pencilfish, apistos, or small corys. It accepts crushed flake, granules, and frozen daphnia or brine shrimp. Wild imports settle fastest in dim, botanical-stained water.
In the wild
Known from the Madre de Dios drainage in southeastern Peru, this tetra inhabits soft forest streams in one of the most biodiverse corners of the Amazon. Keep it warm and soft, 22 to 27 degrees Celsius at pH 5.5 to 7.2, under subdued light.
Good to know
Hyphessobrycon nigricinctus was described by Zarske and Gery in 2004; the name means black-belted, for the dark band that wraps its body. It reaches about 4 centimeters and still travels mostly under its locality name in trade lists.
Did you know
Its home basin borders Manu National Park, a reserve so rich that scientists routinely describe new fish from streams a day's walk from ranger stations.
