A tight-fitting lid is essential as this fish jumps. The aquarium should be planted with floating plants to provide shaded areas. Diet: small insects, brine shrimp, daphnia, and fine dry food. Compatible with other small peaceful blackwater fish. Schooling species, keep in groups of at least 6. Avoid strong currents.
