Care notes
Keep a group of at least 6 individuals in a minimum 60 L aquarium. Water should be soft and acidic (pH 5.5–7.0, GH 1–8, KH 1–5) with a temperature of 24–28 °C. Gentle filtration and subdued lighting are recommended. The omnivorous diet accepts flakes, micro-pellets, and live or frozen foods. Avoid overly active or aggressive tankmates. Regular water changes are essential to maintain the red nose color. This species is sensitive to diseases if parameters fluctuate.
