ID? Bubbles growing on Acan

[KAKLANGLEY]

Noticed a few weeks ago that there was bubbles growing on one of my Acan colonies? Seems healthy and still eating but don't know if there's a reason for these or not.

I don't think I've ever heard a solid answer as to why these bubbles occur, but it might be a form of reproduction.

I have heard its a reproductive response to damage. Something wounds the coral and it forms a bud of tissue that could become a new colony.

Interesting, i have had this happen as well and hope some others here on the forum can give some answers.
