Natural habitat

Bloodfin Tetras are native to the freshwater streams and river tributaries of the Paraná River basin, thriving in environments characterized by tranquil waters with dense aquatic vegetation. This natural habitat helps create a serene environment, essential for their well-being. In the aquarium, replicating these conditions with ample plant cover and a gentle flow is crucial for their happiness.

Where they are found

Found mainly in river systems and floodplains, the Bloodfin Tetra enjoys areas with lush plant life and sufficient open swimming space, allowing them to thrive in a variety of aquatic ecosystems.

Aquarium care

For optimal care, Bloodfin Tetras require a tank of at least 38 liters (10 gallons) with a secure lid due to their propensity to jump. A peaceful community setting is ideal, ideally with at least six members of their own species to enhance their social behavior and coloration. A well-planted aquarium with natural decor enhances both the aesthetic and the well-being of the fish.

Feeding

Bloodfin Tetras are omnivores with a varied diet. They accept a variety of foods, including flakes, micro pellets, and live or frozen options like bloodworms and brine shrimp. Offering a balanced diet promotes their health and enhances their colorful appearance.

Compatibility

These fish are very compatible with other peaceful community species, especially other tetras. They should not be housed with aggressive or significantly larger species that may intimidate or harm them.

Breeding

Breeding Bloodfin Tetras requires soft, slightly acidic water, and a designated breeding tank is recommended. The females will scatter their eggs among the plants, and parents should be separated after spawning to prevent them from eating the eggs. With the right conditions, fry can be raised on infusoria and finely crushed flakes.
