They are often associated with sargassum mats as juveniles, using the habitat for both protection and to forage on invertebrates. Adults forage on other fish, along with shrimp and invertebrates, and are not generally associated with reefs.

Predators:

Mahi mahi, sailfish, tuna, marlin and barracuda.
