Aquarium Information
- Care level: intermediate
- Temperament: peaceful
- Diet: herbivore
- Minimum tank size: 120 gallons (for a small school)
- Compatibility: Generally peaceful with similarly sized, non-aggressive fish. Avoid housing with very small fish or slow-moving, long-finned species as they may nip fins. Best kept in a species-specific tank or with other large, robust characins, cichlids, or catfish.
- Special requirements: Requires a spacious aquarium with plenty of open swimming space. Live plants are often consumed, so artificial plants or very hardy, fast-growing plants (e.g., Anubias, Java Fern) are recommended. Provide driftwood and smooth rocks for enrichment. Excellent filtration is essential due to their size and diet. They are schooling fish and should be kept in groups of at least 5-6 individuals to reduce stress and promote natural behavior.
