Buenos Aires Tetras are very adaptable and tolerate a wide range of water conditions. They do best in spacious aquariums with strong filtration and plenty of swimming room.

🐠 Compatibility

Best suited for active community aquariums with similarly robust fish such as barbs, larger tetras, rainbowfish, and Corydoras. Avoid delicate, slow-moving, or long-finned species, as their activity can cause stress or fin nipping.

Important Notes

Buenos Aires Tetras are known to occasionally nip soft-leaved plants, so hardy plants or artificial aquascapes may be more suitable. Keeping them in larger groups helps reduce fin-nipping behaviour and encourages natural schooling.

The Buenos Aires Tetra is an excellent choice for UK aquarists looking for a tough, energetic, and visually striking schooling fish that thrives in larger community setups.
