Overview
The Madre de Dios tetra is a peaceful Peruvian schooling fish for a soft-water community. It is neither a beginner fish nor a hard one.
Did you know
The Madre de Dios tetra's home basin borders Manu National Park. The reserve is so rich that scientists routinely describe new fish from streams a day's walk from ranger stations.
Caring for the Madre de Dios tetra
Keep Madre de Dios tetras in a group of six or more, in a tank of 15 gal (55 L) or larger. Wild imports settle fastest in dim, botanical-stained water, so keep the light subdued.
Give them warm, soft water at 72 to 81°F (22 to 27°C) and a pH of 5.5 to 7.2. Feed crushed flake, granules, and frozen daphnia or brine shrimp. They are peaceful, and good companions include pencilfish, apistos and small corys.
Good to know
Hyphessobrycon nigricinctus is a characin in the family Characidae, described by Zarske and Gery in 2004. The name means black-belted, for the dark band that wraps its body. It still travels mostly under its locality name in trade lists, and some shops call it the imperial tetra.
In the wild
The Madre de Dios tetra is known from the Madre de Dios drainage in southeastern Peru. It inhabits soft forest streams in one of the most biodiverse corners of the Amazon.
