Note, this species tends to struggle with shipment. Upon arrival this fish may be lethargic and hide for the first week. Housing it in an isolation box may be beneficial while it recovers from shipping. Tusks should be kept in an aquarium no less than 5 ft long. They should be fed a variety of meaty foods; Manila clams, krill, silver sides, and other meaty items will go a long way to ensuring their long-term health. While listed as reef safe with caution, these fish will never touch coral, but likely will eat crustaceans, snails, and potentially large clams.
