Caring for the Pinnistriatus tetra
Keep Pinnistriatus tetras in a school of six or more, in 15 gal (55 L) or larger. Give them flow, high oxygen and a dark substrate.
Plateau headwater tetras like this one want cooler, cleaner conditions than lowland species, so resist the urge to run the tank hot. Keep the water at 72 to 81°F (22 to 27°C) and a pH of 5.5 to 7.0.
Feed crushed flake, granules and small frozen foods. Pinnistriatus tetras are peaceful, so keep them with peaceful company that also likes current.
