and a least 120 Gallon aquarium. It is also essential to provide this fish live rocks to graze on. Once

they get acclimated and start to eat they are fairly hardy species. This fish should be kept with other

calm and non-aggressive tank mates. According to many fish keepers it is advisable not to keep it with

other Surgeonfish. If you plan to keep it with other Surgeonfish the Orange Shoulder Tang must be

added first to the tank. Due to its sensitivity to catch diseases in captivity it is highly recommended to

quarantine him for a period of around 3 weeks. The Orange Shoulder Tang considered reef safe and never

pick at corals or any other invertebrates.
