What's on my favia

[cwetherford]

My favia has had this growth since I got it and idk whatit is and no one I've found does either... It's like the growth bubbles up like a bubble coral where it was originally cut is where the growth is... I've had it for a few months and it just keeps getting bigger with the favia

any help is appreciated
