Notas de cuidado
Maintain temperature 24-28°C, pH 8.1-8.4, salinity 1.020-1.025. A minimum tank size of 300 liters is recommended for one specimen. It is herbivorous: feed with dried algae (nori), spirulina-based flakes, and blanched vegetables. Avoid excess animal protein. It can coexist with other peaceful fish but may be aggressive towards other surgeonfish. Provide hiding places and open swimming space. A protein skimmer is essential. Keep parameters stable with nitrates <20 mg/L and phosphates <0.1 mg/L. Moderate lighting and moderate to strong water flow are appreciated.
