I have never seen my anemone this blown up in my life it usually is extremely close to the rock. It is fully extended from the rock and nothing coming out it’s mouth.
I noticed a couple of mine stretching out last winter and looked just like Slocke’s pictures. I’m pretty sure they were spawning because a bunch of babies popped up a few weeks later. They just started doing it again a couple days ago so I think it must be a seasonal spawning thing.
