 Preliminary dietary information collected from the North West Shelf of Australia shows "C. fulvoguttatus" and "C. gymnostethus" inhabit very similar habitats, and are able to do so by partitioning their diets, with "C. fulvoguttatus" taking more fish and cephalopods, while "C. gymnostethus" predominantly takes crustaceans.The only data on reproduction in the species come from Palau, where large spawning aggregations form in the third quarter of the lunar month.Spawning takes place in South Africa over the summer.
