White stringy thing?

[afamuz]

Hey guys, 6 week old tank and i noticed a stringy white thing that’s attached on my rock. Any ideas what it is and what’s causing it?

I'm not an expert, but it doesn't look like anything is on the rock is living to extrude that. Is it a long human hair by chance?

My slugs or corals sometimes give these off, maybe just mucus?
