It is solitary for most of the year, but during reproduction it lives in groups for some weeks: fully-grown dentex stay together just two to three weeks during spring in the warmer water near the surface.
Den lever for sig selv det meste af året, men under reproduktion lever den i nogle uger i grupper, hvor fuldvoksne tandbraser forbliver sammen to til tre uger i foråret i det varmere vand nær overfladen.
