Substrate dweller?

Any clue what this trail is from? I can see movement but the culprit is suuuuuuper tiny. Some type of worm maybe?

Thanks. Are they reef safe?

It could also be a pocket of gas.

Saw some lateral movements in the substrate. Looked like something burrowing. Just couldn’t see what it was.

I think I’ve seen amphipods in similar burrows in my tank. Otherwise I agree that a bristleworm burrow is possible. I doubt it’s anything to worry about.

they are fine as long as you don't touch them. there is something that will eat them i think a shrimp species. i don't remember which one.

I’ve seen my pistol shrimp snacking on bristle worms, not sure if that’s the species you mean though.
