Overview

The bloodfin tetra is a tough, adaptable schooling tetra and a good choice for a first community tank.

Did you know

Bloodfin tetras are a reasonable choice for a tank without a heater, as long as the room is warm.

Caring for the bloodfin tetra

Keep bloodfin tetras in a group of six or more, in 20 gal (75 L) or larger. A planted tank with a bit of flow and open swimming room suits them. They are strong jumpers, so keep the tank covered.

Keep the water at 72 to 82°F (22 to 28°C). They handle a wide pH range, from 6.0 to 8.0. Feed flake and micro pellets, with the occasional frozen brine shrimp or daphnia.

They swim in the middle and upper levels and are active. They can get nippy when kept in too small a group. Bloodfin tetras are egg scatterers with no parental care, and the eggs typically hatch in a day or two. Breeding them is a moderate challenge.

Good to know

The bloodfin tetra is a member of the family Characidae. It has a silver body and the red fins that give it its name. It is long-lived for a small tetra, and its conservation status is Least Concern.

In the wild

Bloodfin tetras come from clear, shallow rivers and streams with some current across Argentina, Paraguay and Brazil. The bottom is usually sand or mud with scattered rocks and leaf litter, and the water runs slightly acidic to neutral.
