Groupers are solitary carnivores that hunt near the bottom usually at dusk. 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/Gracila-albomarginata.html
