Green bubble coral has mouth bubble

[ShanTank]

Hello

9 year old green bubble coral seems to have bubble, with tiny brown spots coming out his mouth.
Has anyone had this or know what it is?
Thanks so much!

Looks like it is about to spawn.

Thank you so much for the response! Is there anything I should be doing/not doing? And um.. what is spawning?

It means the coral is happy and releasing reproductive goodies.

No action is needed, my fish will eat what the coral releases.

Great, thank you!! He’s been through a lot and thought I lost him a few times so glad this is a good sign

Update.. looks like he’s been trying to close up a little; at least to cover bubble mouth
