white milky substance

So i was doing my tank maintenance today and after i was complete there was a white milky like substance (some might say it looks like man seed) that came out from numerous holes in the rock. Does anyone know what this might be.

I saw a video posted before on this site by Mr x from YouTube. It was bristle worm spawning Look up bristleworm spawning on YouTube and I bet that's what you saw.

that is what it was. My wife said she saw tentacles coming out of the rock. It was actually just bristle worms.
