Common Name
Congo Tetra
Origin and Habitat
Congo Tetras are native to the Congo River drainage in Central Africa. They are commonly associated with inland rivers and quieter zones with lots of benthic and floating vegetation, plus driftwood and submerged branches that soften the current and light.
Biotope and Natural Setup
If you want a true Congo basin feel, build the tank around soft light, dark structure, and a clear runway of open water for schooling.
Use a longer footprint and leave the center open for swimming. Then build the edges with driftwood, root tangles, and rounded stones, and let plants do the shading. A darker substrate and a mild tannin tint help their colors glow without blasting the tank with bright lighting.

The Congo Tetras are active and colorful when kept in a well-mimicked African biotope. I used driftwood and leaf litter, and the fish swim beautifully in the open area. The dark substrate and soft lighting really bring out their natural hues. Easy to care for and very social in groups.
Anthony Mills –
They thrive in a tank with plenty of cover and open swimming space. I added floating plants and submerged branches. The fish stay calm and show vibrant colors under soft lighting. A great addition to a community tank with other peaceful species.

After setting up a 120-liter tank with driftwood and dark sand, the Congo Tetras became a highlight. They school well and don’t stress easily. The tannin-rich water from leaf litter enhances their appearance. Highly recommended for African cichlid enthusiasts.
