Serennid are brightly coloured. They are all carnivores although some feed on zooplankton most feed on fish and crustaceans. Food is drawn into their mouths by a powerful suction when they open their overly large mouths and then swallowed whole.
Spawning is seasonal and controlled by the moons phase. Ref: https://www.fishbase.se/summary/Caesioperca-lepidoptera.html
