White stuff squirting from live rock

[Barry_Cuda]

I wish I had a photo of this, but it happened so fast I barely spotted it. I have a 6-week-old tank with a mix of aquacultured live rock and Real Reef Rock. A couple times now (second time being just a minute ago) I have seen a sudden squirt of some white ropey stuff from somewhere in the live rock. It rapidly disperses in the water column and doesn't seem to cause any issues. I assume something in the LR is spawning, but I have no idea what. Any thoughts on what it might be?

Stomatella or brittle stars.
I’d wager stoma if it looked like little volcanos in the tank

6 weeks in and you already have critters getting freaky. Your tank is going to be fun to watch mature.

This was stomatella for me also when I had it happening when my system was new.
