Hello,
I looked at my zoas today shortly after the light went on. There was a strange black rippling substance peeking out of the "mouth" at the center of the head. I took some photos but it's a bit hard to see. The black substance has now disappeared and is no longer there on the zoa.
Any ideas what this is? And what I should do about it?
