Ok so this might sound crazy but it’s true. So I was putting a rock covered in zoas in my tank when I noticed one of the heads came off and was kind of bouncing around the bottom of my tank. I ended up just leaving after it blew into a little cave in the rock thinking maybe something would find it and eat.. well that was a month and half ago and now I see this growing out of the rock?? I touch it thinking it was that head to take it out and it sucked back in. What could it be !!? My tank is only 2.5 months old.
