I got this rock about a week ago and am almost finished curing in my pico tank. Before I move things around to scape I was curious if anyone has any idea what these are? The white worm like one extends/retreats and seems to prefer low light.

Kinda hard to make out at the distance and without the rest of it, but maybe a peanut worm?

Thank you for your reply! It doesn’t seem to have the mouth of a peanut worm? Here are some better pics.
