The trumpeter whiting is a benthic carnivore, consuming a variety of crustaceans, polychaetes and molluscs, with a dietary shift occurring as the mature and move into deeper waters.

The species is known to undergo a dietary shift as it grows to adulthood.

The species also appears to have dietary shifts as it grows, however in all size classes fish are the dominant prey.
