The Rhino leatherjacket (Pseudalutarius nasicornis) is another interesting filefish with similar physical characteristics to the Orange Spotted Filefish or Harlequin Filefish (Oxymonacanthus longirostris). The Rhino Filefish is not commonly seen in the trade but despite that, doesn’t carry a heavy price tag when it is available. They are a very hardy fish and will eat prepared foods readily. Flakes, small pellets, and frozen mysis all make good foods. They may even eat algae sheets which we recommend. They have the signature mouth shape of some other coral-nipping filefish so caution should be taken when adding to a reef system. Photo courtesy of Sanjay Joshi
