Smoke signals from live rock

[greech]

My tank started looking cloudy last night but couldn't tell why. I turned off my pumps to feed and now I see where it is coming from but I don't know what it is. I just grabbed my phone so the video isn't great and sorry for the background noise but I hope you can see it. Seems this has been going on for the last 24 hours or so...

It comes out of the left side and top of the cave. There are no corals or anything under there.

Bristleworm spawning, or something very similar...

Interesting. I'm watching it really coming out now on almost the entire boundary of the cave. Very cool!
