1 of two things. It is expelling zooxanthella (photosynthetic algae) or maybe a parasite. I don’t know if nudibranches eat acans but it could be a pest.

Could something bright green have fell into it? Tentacle is euphillia or something, maybe a tentacle from a Nem?
That’s what it was a piece of my hammer I don’t know why I didn’t put the two together I guess I just assumed the worst haha
