As omnivorous creatures, Minor Tetras have a varied diet that includes both plant and animal matter. In their natural habitat, they feed on small insects, algae, and zooplankton. In captivity, they readily accept high-quality flake or pellet foods supplemented with live or frozen treats such as bloodworms or brine shrimp. Providing a diverse diet will ensure their optimal health and vibrant colors.

How to keep the Minor Tetra at home

Creating a suitable environment for Minor Tetras requires careful attention to their habitat and water parameters:

Tank size: Provide a spacious aquarium with a minimum capacity of 40 liters (10 gallons) to accommodate a school of Minor Tetras. Ensure the tank is well-planted with plenty of hiding spots and open swimming areas.
Water parameters: Maintain a stable water temperature between 22-26°C (72-79°F) and a pH level ranging from 6.0 to 7.5. Regular water changes and filtration are essential to maintain optimal water quality.
Tank mates: Minor Tetras are peaceful fish that can coexist with a wide range of community tank mates, including other small tetra species, rasboras, and peaceful bottom dwellers. Avoid keeping them with aggressive or fin-nipping species to prevent stress and injuries.

With their captivating beauty and gentle temperament, Minor Tetras are a delightful choice for beginner and experienced aquarists alike. By providing them with a suitable environment and a balanced diet, you can enjoy watching these charming fish thrive and flourish in your own home aquarium.
