Anoplogaster cornuta is carnivorous. Juveniles feed on crustaceans, while adults feed primarily on fish and shrimp. They have been observed to feed on fish one-third their size, necessitating the mechanism of reversed direction ventilation when feeding. Their large size allows them to swallow most prey whole. Due to their high mobility relative to other pelagic teleosts, it has been speculated that they are aggressive hunters. Other studies have suggested the contrary, describing them as voracious ambush predators.
