Keeping Brown Surgeonfish in an aquarium requires the right conditions.

Aquarium Information

  • Care level: intermediate
  • Temperament: semi-aggressive
  • Diet: herbivore
  • Minimum tank size: 120 gallons
  • Compatibility: Generally compatible with other large, active fish. Can be aggressive towards other surgeonfish, especially those of similar size or coloration. Best kept singly or in very large aquariums with multiple surgeonfish introduced simultaneously.
  • Special requirements: Requires a well-established aquarium with ample live rock for grazing and hiding. A strong current is beneficial. High-quality marine flake and pellet foods supplemented with various marine algae (e.g., Nori) are essential for their health and to prevent head and lateral line erosion (HLLE).
