The ones i had were about 7 inches in diameter. I cant find a good pic but there was one that was 7" and a few that were 5-6". they just grow to big and too fast!
It looks identical to the hairies I see in stores, covering entire rocks! In any case, techically, A hairy mushroom IS an anemone!

Read several paragraphs down, just above ricordias.
It moved around before when I first got it, not very far, but it likes where it is now. Hasn't moved in a few weeks. It took 2 days to move a few inches.
It looks like this because I just turned on the lights for the pics. Usually, it is pretty flat and spread out. Twice the size as these pics. Takes the shape of the rock contour.
