Is my hammer splitting, or?

This is my first hammer coral. I've had it since October 2017. It really hasn't done much since I've had it. I just now noticed something happening with one the heads on the coral and wondering what is going on here?! Here's a few pics...

I'm pretty sure it's splitting as I see two distinct mouths. I have never kept these coral though. So I'm just not sure.

yep it sure is.it will probably take a few more weeks to complete the process.it's really cool to watch this process and hopefully you get to see it over and over again.once the colony gets larger it's harder to see sense the full heads block the view.

Very cool! I've kept duncan coral, acans, and candy cane but none of those split this. I feel like this new system is finally starting to come around after some initial struggles.
