Care notes

Maintain a temperature of 23 to 28°C and a pH of 6.0 to 7.0. General hardness (GH) should be below 10°d. A tank of at least 60 liters is recommended for a school of 6 to 8 individuals. Diet is omnivorous: accepts flakes, micro pellets, and live or frozen foods like brine shrimp. Provide gentle filtration and subdued lighting. Floating plants and leaf litter create a reassuring environment. Avoid overly active or aggressive tankmates. Breeding in captivity is possible but tricky, requiring very soft and acidic water.
