Hey guys. I’ve had this for like 4 months and today I noticed this thing on the side. It’s very small. Maybe 3-5 millimeters wide, doesn’t seem to be hard, moves with flow.
I agree looks like a small clove polyp. I've had my run ins with them and they're not fun. I'd use some aiptasia x or epoxy and try to kill or cover it up before it spreads.
