Was it brown & slimy? It may have pooped. It's hard to tell from the pics what it is. Your anemone will expell waste every so often. Thats what it looks like to me.
Like I said in the afternoon it was gone. I hope it wasn't part of the anemone because nobody seems to know what it is. Now this morning I found it looking like this.... and by the afternoon it looked fine again. Maybe I'm just too new & too nervious?????
Yea he's pooping! They will kind of look depleated afterwards, but in a couple of hours he will puff back up. Nothing to worry about, it's normal. I scoop the poop out when I see it, sometimes it will stick to things and look nasty.
