Keeping Rock Beauty in an aquarium requires the right conditions.

Aquarium Information

  • Care level: intermediate
  • Temperament: semi-aggressive
  • Diet: omnivore
  • Minimum tank size: 100 gallons
  • Compatibility: Can be kept with other semi-aggressive fish of similar size. May be aggressive towards other angelfish or smaller, docile species. Not reef safe, as it will nip at corals and sessile invertebrates.
  • Special requirements: Requires a well-established aquarium with plenty of live rock for grazing and hiding. A varied diet including marine algae, spirulina, high-quality angelfish preparations, and occasional meaty foods is crucial for its health and coloration. Good water quality and stable parameters are essential.
