Caring for Rosy Tetras in the home aquarium is relatively straightforward, but there are some key considerations to keep in mind:

Tank size: A minimum tank size of 40 liters (10 gallons) is recommended for a small school of Rosy 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: Rosy Tetras are peaceful fish that can coexist with a wide range of tank mates, including other peaceful community fish like tetras, rasboras, and livebearers. Avoid keeping them with aggressive or fin-nipping species.
Dangers and risks: While Rosy Tetras are generally hardy and disease-resistant, they can be sensitive to sudden changes in water parameters. Monitor water quality closely and avoid overcrowding the tank to prevent stress-related illnesses.
