Just recently noticed one of my hammers has some sweepers. Is this a feeding response or aggression? Only thing near it is other hammers

Following. Mine do that from time to time. No apparent rhyme or reason, and no damage to other corals.
It could be either, feeding response or a defense. I never paid to much attention unless a competing coral was getting to close. If it's other euphyllia nearby I would just keep an eye out but usually like species can be kept together without issue.
