The yellowfin seabream is a shallow-water warm-water demersal fish that lives in inshore waters as well as estuarine bays. It does not have long-distance migratory habits, but it does have a distinct reproductive migration behavior, moving from inshore or brackish freshwater waters to higher-salt deeper waters two months prior to spawning, a process that takes about two months, and then returning to inshore again when spawning occurs.
