Natural habitat

The Broken Line Tetra is found exclusively in the Rio Paraguay Basin of Brazil, inhabiting slow-moving rivers and tributaries with riparian vegetation. These fish thrive in calm waters that are rich in organic matter, making them well-adapted to their habitat.

Where they are found

This species is mainly found in slow-moving waters within tropical environments characterized by the presence of substratum foliage and driftwood.

Aquarium care

These fish prefer a well-planted aquarium with hiding spots, such as driftwood and foliage, which can help reduce their shyness. Soft, dim lighting and a substrate of fine sand are recommended to mimic their natural conditions. Regular water changes and maintaining stable water parameters will ensure their health and well-being.

Feeding

A varied diet is crucial for health; include high-quality flake foods, micropellets, and small frozen foods like bloodworms and daphnia to meet their nutritional needs.

Compatibility

Broken-Line Tetras are ideal for community tanks housing small, peaceful species. Favorable tankmates include small Corydoras, dwarf cichlids such as Apistogramma, and non-aggressive loaches.

Breeding

Breeding Broken Line Tetras requires a separate breeding tank with soft water. Raising the temperature gradually can trigger spawning, and fine-leaved plants should be provided for egg scattering. After spawning, it is crucial to remove the parents to prevent them from consuming the eggs. The fry hatch within 24-36 hours and should be fed with micro-foods until they grow larger.
