This response from Bruce Collette at the Smithsonian Institution:You are having trouble because your fish is not a needlefish. As shown by the caudal filament, it is a cornetfish, family Fistulariidae. The extended snout opens in a relatively small mouth, not two separate tooth-studded jaws like needlefishes have. They may be solitary or occur in small schools. They feed on small fishes and crustaceans. While I am not an expert in this family, based on geography, they should be Fistularia commersonii.
