Overview

The Melanostichos tetra is a striped schooling tetra for the middle of the tank. It is robust enough for a general soft-water community, and it suits a dedicated Tapajos biotope as well. It is a good pick once you know the basics.

Did you know

The Melanostichos tetra shares one small river with the notidanos tetra, another species described in the same paper. The two neighbors entered the scientific record side by side.

Caring for the Melanostichos tetra

Keep Melanostichos tetras in a group of six or more, in a tank of 16 gal (60 L) or larger. They are active swimmers, so give them length to run. A dark substrate, plants along the back and open water in front suit them.

Keep the water at 72 to 81°F (22 to 27°C), with a pH of 5.5 to 7.0. They accept all standard small foods.

Melanostichos tetras are peaceful. In a Tapajos biotope, corys from the same drainage make good companions.

Good to know

Hyphessobrycon melanostichos is a characin in the family Characidae, described in 2006 and also sold as the Tapajos blackline tetra. The name means black line, for the thick dark stripe that runs from the gill plate to the tail. In healthy adults, the stripe pairs with a blue-green sheen along the upper body.

In the wild

The Melanostichos tetra lives in the Rio Doze de Outubro in the upper Tapajos basin, in Mato Grosso, Brazil. The river runs clear and soft through the forest.
