Keeping Silver Dollar in an aquarium requires the right conditions.

Aquarium Information

  • Care level: intermediate
  • Temperament: peaceful
  • Diet: herbivore
  • Minimum tank size: 120 gallons (450 liters) for a school of 6-8 individuals
  • Compatibility: Generally compatible with other peaceful, similarly sized or larger fish that can tolerate similar water parameters. Avoid very small fish that might be mistaken for food, or aggressive species. Good tankmates include larger tetras, cichlids (e.g., Geophagus, Uaru), large plecos, and other peaceful characins.
  • Special requirements: Requires a well-filtered aquarium with ample swimming space. Live plants are often consumed, so artificial plants or very hardy, fast-growing plants (e.g., Anubias, Java Fern) that can withstand grazing are recommended. Provide open swimming areas along with some hiding spots created by driftwood or rocks. They are schooling fish and should be kept in groups of at least 6-8 individuals to reduce stress and encourage natural behavior.
