Hi everybody,
That's kind of the scenario I'm trying to describe though I doubt that's what it literally is. I've heard of Fungia reproducing by having small plates form on or near it, but that doesn't seem to be what mine has done. Mine seems to be forming a new mouth on the side of the body that doesn't look like it has any plate structure surrounding it. Will it eventually form a plate and leave? I tried feeding the extra mouth and it does eat, which is pretty cool! If anyone has had this happen or knows what will happen, please let me know. I included a picture of a closeup of the mouth for reference. The extra mouth is boxed in red.
