What just squirted something into my tank?

[MarkH81]

I bought some new corals for my tank yesterday, acans, zoas and a Duncan which have all settled in nicely. Only when I looked at one of the rocks today i noticed that there

was a small object shooting out bursts of a white substance into the tank. I’ve never seen anything like it and naturally I’m slightly concerned for my corals and fish not knowing what has now sprayed into the water. The same object has now slowly crawled away. I have attached a video and have captured 3 bursts. Can anyone let me know what this is and is it something I should be concerned about? Many thanks, Mark.

I'd say some type of spawning event.... But not sure what might be spawning from that video.

Do you have snails, that's what snails spawn like

I can't load the video, but I agree that it sounds like something spawning. Look at videos of spawning snails to check. Harmless to the tank.

Hmm shooting milky white stuff. Now what could that be lololol

I can't view the video but my guess would be stomatela snails, looks like a small puff of smoke, spawning.
