Care notes

Aquarium of at least 100 liters for a group, but 60 liters can work for a small group. Temperature 24-28°C, pH 6.0-7.5, GH 5-12. Slightly acidic to neutral water is ideal. Diet: fine flakes, micro pellets, brine shrimp, daphnia. Very peaceful species, ideal for a community tank with calm fish. Avoid overly large or aggressive species. A planted tank with shaded areas is recommended. Breeding is easy: eggs are laid on fine plants or a mop. Fry are small and require very fine food.
