Overview
The red devil tetra is a tiny, peaceful schooling fish for a nano community tank. It is a step up from the easiest fish.
Did you know
Red devil tetra males and females look so different that a school seems like two species swimming together. Shops occasionally sell the two sexes as different fish.
Caring for the red devil tetra
Keep red devil tetras in a nano or small planted tank of 10 gal (38 L) or more. Tannins and gentle flow suit them.
Keep the water at 73 to 82°F (23 to 28°C), with a pH of 5.0 to 7.0. Their food must be tiny, such as crushed flake, micro granules and brine shrimp nauplii.
Red devil tetras are completely peaceful and suit nano communities, where they swim in the middle of the tank. Keep ten or more of them to get the full two-tone effect.
Males color deep red, while females stay yellow-gold. In a group, the red males court the yellow females. Red devil tetras suit breeding projects, and breeding them is moderately difficult.
