🏠 Tank Size: 60L+ recommended
🌡️ Temperature: 24–28°C

Green Fire Tetras do best in aquariums with open swimming space and some planted areas. Good water quality and moderate flow help maintain their colour and activity levels.

🐠 Compatibility

Best suited to active community aquariums. They mix well with other robust peaceful fish such as larger tetras, rasboras, barbs, and bottom dwellers like Corydoras. Avoid very slow-moving or long-finned species, as their energetic behaviour may cause stress or fin-nipping.

Important Notes

Green Fire Tetras are more active than many other tetra species and may nip fins if kept in small groups. Keeping them in larger shoals helps reduce this behaviour and encourages natural schooling.

The Green Fire Tetra is a great choice for UK aquarists looking for a vibrant, energetic fish that adds shimmer, movement, and personality to community aquariums.
