Red Eye Tetras are very adaptable and thrive in a wide range of aquarium conditions. They prefer open swimming space with some planted areas for cover.

🐠 Compatibility

Best suited to active community aquariums. Ideal tank mates include barbs, larger tetras, rainbowfish, Corydoras, and other robust peaceful species. Avoid very slow or long-finned fish, as their activity level can cause stress.

Important Notes

Red Eye Tetras are strong swimmers and can become fin-nippy if kept in small groups. Keeping them in larger shoals significantly reduces this behaviour and encourages natural schooling.

The Red Eye Tetra is a fantastic choice for UK aquarists looking for a hardy, active, and visually striking schooling fish that performs well in both beginner and established community aquariums.
