Diet
Omnivorous; thrives on a diet that includes high-quality flake foods, small pellets, and live or frozen foods such as brine shrimp, daphnia, and bloodworms.
Community Compatibility
Ideal for community tanks with other peaceful, similarly sized fish. Their calm nature makes them compatible with a variety of tank mates, including small tetras, rasboras, and dwarf cichlids. Avoid large or aggressive species that may intimidate or prey on them.
