Overview
The Notidanos tetra is a small, peaceful schooling fish for a planted tank with soft water. It is a good pick once you have some experience.
Did you know
The Notidanos tetra and another tetra new to science came out of the same little river, in the same 2006 paper. Of the pair, this is the one that stands out with a taller dorsal fin rather than a longer stripe.
Caring for the Notidanos tetra
Give Notidanos tetras a planted, dark-floored tank of 15 gal (55 L) or more, with gentle current. Keep the water soft, at 72 to 81°F (22 to 27°C) and a pH of 5.5 to 7.0. They eat all standard small foods.
Notidanos tetras are peaceful and suit a softwater community with corys and dwarf cichlids. You can also pair them with the melanostichos tetra for a two-species biotope from one small Brazilian stream.
Males develop a taller, sail-like dorsal fin and display with it constantly in groups. Keep six or more so the males have an audience, since the dorsal displays are the show.
Good to know
The Notidanos tetra, Hyphessobrycon notidanos, belongs to the family Characidae. Its name is drawn from the Greek for sharp-backed, after the dorsal fin of the males.
In the wild
The Notidanos tetra lives in the rio Doze de Outubro, in the upper Tapajos headwaters of Mato Grosso, Brazil. It shares this clear, soft forest water with the melanostichos tetra.
