Overview

Keep a school of six or more with peaceful current-loving company. It feeds on crushed flake, granules, and small frozen foods. Plateau headwater tetras appreciate cooler, cleaner conditions than lowland species, so resist the urge to run this one hot.

In the wild

This tetra inhabits clear headwater streams of the upper Tapajos in Mato Grosso, cool-leaning water with steady current. A tank with flow, high oxygen, dark substrate, 22 to 27 degrees Celsius, and pH 5.5 to 7.0 matches its plateau home.

Good to know

Hyphessobrycon pinnistriatus reaches about 3.6 centimeters; its name means striped fin, after the dark streaking through its fins that sets it apart from plain-finned relatives in the same headwaters.

Did you know

Where most striped tetras wear their pattern on the body, this one signed its fins instead, and the fin stripes are exactly what the scientific name records.
