Only one study has thoroughly recorded the diet of the imposter trevally, which was carried out in Albatross Bay, Australia. It was found teleost fish made up 73% of its diet, cephalopods 16% and a variety of crustaceans including brachyurans and stomatopods the remainder. It is thought that the coexisting C. coeruleopinnatus and C. malabaricus use diet partitioning to allow this cohabitation. Nothing is known of the species reproduction and growth patterns.
