Aquarium Information
- Care level: intermediate
- Temperament: peaceful
- Diet: omnivore
- Minimum tank size: 15 gallons (57 liters) for a small school
- Compatibility: Excellent for community tanks with other small, peaceful, soft-water fish such as other tetras, dwarf cichlids, corydoras, and rasboras. Avoid housing with large or aggressive fish that may prey on them.
- Special requirements: Requires a well-established aquarium with dense planting, driftwood, and subdued lighting to mimic its natural blackwater habitat. A dark substrate can enhance their coloration. They thrive in schools of 6 or more individuals, which reduces stress and encourages natural schooling behavior. Excellent water quality with regular small water changes is crucial.
