Natural habitat

Penguin Tetras are native to slow-moving rivers and streams in the Amazon Basin, primarily around the borders of Brazil and Colombia. They inhabit areas with dense vegetation and floating plants, allowing them to hide and forage efficiently.

Where they are found

The species inhabits various freshwater environments within its range, often preferring blackwater streams and tributaries that are densely vegetated. The ecological conditions of these habitats include low light penetration and a warm, stable climate, which contributes to its vibrant color patterns and schooling behavior.

Aquarium care

To maintain healthy Penguin Tetras, it's essential to provide a well-planted aquarium that mimics their natural habitat. Regular water changes are needed to stabilize water parameters, and soft, slightly acidic water is preferred.

Feeding

Penguin Tetras should be fed a varied diet consisting of high-quality flakes, small pellets, and occasional protein-rich foods, such as live or frozen brine shrimp and bloodworms. Ensuring sufficient food distribution is key, especially in community tanks.

Compatibility

Penguin Tetras are compatible with a variety of peaceful community fish. They do best in schools and should be kept with similarly non-aggressive species to foster a harmonious environment.

Breeding

Breeding these tetras can be achieved in a separate tank with soft, slightly acidic water. They are egg scatterers, so fine-leaved plants or spawning mops should be provided for them to lay their eggs. After breeding, it’s advisable to remove the adults to prevent them from eating their fry.
