Minimum Tank Size: 120 litres (approximately 30 gallons) to allow sufficient swimming room and territory establishment.
Reef Compatibility: Yes. Convict Tangs are generally reef safe and do not harm corals or invertebrates.
Lighting & Water Flow: Standard reef aquarium lighting and moderate water flow are suitable to mimic their natural environment.
