Natural habitat

Boehlkea fredcochui, commonly known as Cochu's Blue Tetra, is native to the Rio Marañón in Peru. They inhabit warm, acidic waters with dense aquatic vegetation, which provides both shelter and breeding grounds.

Where they are found

This species is primarily found in slow-moving waters with abundant vegetation, where they often swim in the upper levels of the water column.

Aquarium care

To care for Blue Tetras, ensure a well-maintained aquarium with regular water changes. They require a spacious environment, ideally a minimum of 113 liters (30 gallons), and should be kept in groups of at least five to reduce aggression. Providing hiding spots with plants and decor will help them feel secure, while open spaces accommodate their swimming habits.

Feeding

Cochu's Blue Tetra accepts a variety of foods, including high-quality flake food and frozen alternatives. A varied diet ensures optimum health and color expression. It is recommended to offer smaller portions multiple times a day rather than one large feeding.

Compatibility

Blue Tetras are community-safe fish and can coexist with other peaceful species. However, their occasional nipping behavior may pose a problem when housed with long-finned fish.

Breeding

Breeding is straightforward; provide a separate breeding tank with soft, slightly acidic water and ample plants. After spawning, remove the adults to prevent them from eating the eggs.
