Hole in cabbage coral

[mrjohnreed]

I bought this cabbage corals about a week ago. It looked good and I didn't see any issues with it. Now I see a small round hole in the middle of the coral. What could be causing this?

Could be asexual reproduction by lateral fission.
An image under white lighting would be off assist.

my leathers have done that a few times on their own, either heals or they become 2

I was gonna say splitting as well.

I have not found many predators for these leathers. I have 1 huge cabbage I have to give away to anyone local as it takes up way too much space and I already have one getting too big that a tiny bit had stuck to a rock and is now a nice size piece! My Steve Tyree toadstool has been fragged several times and it is getting to where I need to do it again but I still have frags left from the last time! So me and leathers well, what can I say, they grow like wild fire.
