Care
Care notes
Ideal temperature between 24 and 28°C, very acidic pH 4.0 to 6.5, GH below 5. Water must be soft and rich in tannins (catappa leaves). A minimum tank of 100 liters is required for a group of 6 to 8 individuals. Feed with varied foods: bloodworms, brine shrimp, small insects, and quality flakes. Avoid strong currents. Compatible tankmates: small characins, corydoras, other rasboras. Water changes should be frequent but moderate to avoid disturbing chemistry. Breeding is difficult, requiring very soft and acidic water.
