Pooping, spawning, or expelling something else?

So my Space Invader pectinia did this yesterday, and it was all the mouths of the eyes at the same time, this went on

for around an hour.

Did you get a video?

No just the pics, the fluid it expelled was brownish, you can see it a little if you zoom in on the mouths. It was much more coming out when I first noticed it.
