Buenos Aires Tetra

A robust, active tetra with a silvery body and colorful fins. Adults can reach around 6–7 cm and are considerably more energetic than many small community tetras.

Aquarium and care

Keep a group of at least eight in a roomy aquarium with strong filtration and open swimming space. Moderate temperatures and stable freshwater suit this species. Choose hardy plants carefully, as softer plants may be eaten.

Feeding

Offer a varied omnivorous diet including prepared foods, frozen foods, and vegetable matter. Adequate feeding does not guarantee that plants will remain untouched.

Temperament and tank mates

Best with active, sturdy companions. Avoid very small fish and slow, long-finned species; a large group and ample space help reduce fin nipping.
