Optimal health for Congo Tetras is achieved in a stable environment with good water quality, a balanced pH level of around 6.0 to 7.5, and temperatures between 72°F and 82°F.

A varied diet, including quality flake food, frozen or live brine shrimp, and bloodworms, is essential for maintaining their vibrant colors and overall vitality.

In case of illness, early detection and treatment, often involving specific medications and improved tank conditions, are vital for recovery.
