So to start the story I have 2 zoa colonies taking over the rock I have them all on. In an effort to save the ones getting taken over I pulled the rock out and started fragging the ones I wanted to save. Under the main rock I see a small piece of a frag plug sitting in the sand. Picked it up and flipped it over and there were three heads of a zoa I thought I lost months ago. Glued that to a smaller rock so I don’t loose them again and put them in a dark spot in the tank. I can still see a little color coming through on them but I’m confident they’ll make it. I’m just amazed that after probably 4 months upside down under a rock they’re still alive.
