Care notes

Temperature 24 to 28°C, pH 6.0 to 7.0, soft GH (2-8°d). A tank of at least 40 liters is sufficient for a group of 6 to 8 individuals. Diet is insectivorous: microworms, brine shrimp, fruit flies, and fine flakes. Filtration should be gentle. Subdued lighting and floating plants are recommended. A lid is essential. Avoid large fish. Breeding is rare in captivity, requiring very soft and acidic water.
