The trumpetfish, Aulostomus maculatus, is a long-bodied fish with an upturned mouth; it often swims vertically while trying to blend with vertical coral, such as sea rods, sea pens, and pipe sponges. (Wikipedia)

The Atlantic trumpetfish, Aulostomus strigosus (or incorrectly Atlantic coronetfish) is a species of trumpetfish in the family Aulostomidae. It is a tropical marine fish found in shallow coastal waters in the eastern Atlantic Ocean from Mauritania to Namibia. Like other trumpetfish, they eat mainly small fish and often shadow other piscivores while hunting. (Wikipedia)
