Also, we just received a Bubble Tip Anemone. I put into the tank and no more than half an hour later he opens his mouth very wide and what looks like a huge cotton wad (notice I didn’t say ball, this was much bigger) is sitting inside. He stayed like this most of the evening. So I called my LFS and they said he was removing waste (aka Going Potty). So this morning when we got up he had let little bits of this stuff go throughout the night and it was all over the tank. Now he is much smaller but looks healthy, base is a rich brown color, tentacles are bright green and flowing around with current.
