Possible bad anemone on 2 day old LR?
I’m new to reefs but based on some research I believe I have that anemone that stings other corals on my LR. And its supposedly spreads fast right? I think a couple more have already started sprouting up. It seems to be growing quite fast and there are already 2 in the tank, plus I think that red circle in the third image is a baby? I don’t know. Also, I was not able to take a picture but at one point there was a small black worm looking guy, maybe half a centimeter long, on the unidentified thing, would he most likely be friendly?
