Pest or not ? Releasing some substance.

Got first corals for my qt tank two days ago, and just happen to sit by tank when this happened.
Quickly grabbed camera, and recorded, this took a while, a minute or so.
Can't get good pic now, but maybe later tonight, as I have macro lens getting delivered today.
It seems like it's pollinating.
What is this stuff ?

It's taking a poop?

Looks like a poop.

Ok, what is it though ?
Is it part of Ricordea, or is it something else ?

Coral spawning, no problem.

If that is coral spawning that is super cool
