Overview

The Peruvian tetra is a slim, peaceful schooling tetra for a soft-water community tank. It is best kept by someone past the beginner stage.

Did you know

The Peruvian tetra has a soft blue and gold glow along the top of its black stripe. That glow is why the trade often calls it the blue loreto tetra.

Caring for the Peruvian tetra

Keep Peruvian tetras in a shoal of at least eight to bring out their blue shimmer. Give them 16 gal (60 L) or more, with a dark substrate and gentle lighting to deepen the colors.

Keep the water soft and clean, at 72 to 81°F (22 to 27°C) and a pH of 5.5 to 7.0. They are peaceful and mix well with other small characins and dwarf cichlids. Breeding them is moderately difficult.

Good to know
