Temperament: Generally peaceful but can be territorial towards conspecifics or similar tang species. Best kept singly or in a very large tank with ample hiding spaces.
Diet: Primarily herbivorous. Provide a varied diet rich in marine algae, seaweed sheets, and high-quality herbivore pellets or flakes. Supplement with occasional meaty foods to ensure balanced nutrition.
Minimum Tank Size: 250 litres (66 gallons) or larger to accommodate its active swimming behaviour and adult size.
