Ornate Tetras are peaceful and visually striking freshwater fish that thrive in groups of six or more in a planted tank of at least 15–20 gallons. They prefer slightly acidic to neutral water (pH 6.0–7.5), soft to moderately hard water, and temperatures ranging from 73–82 °F (23–28 °C). These tetras are omnivores and benefit from a varied diet of quality flakes or pellets, along with live or frozen foods such as bloodworms and daphnia. A natural setup with driftwood, leaf litter, floating plants, and subdued lighting helps reduce stress and enhances their colors.
