I've had my fish tank about 10 months now, I've bought 3 chromis, ( new to this excuse me ) the finding nemo fish, a banded shrimp, 2 crabs, 2 horse shoe crabs, a snail and anemone. But one day this weekend I got home from work and when I went to feed the fish I seen something go back into my live rock. Two days later I saw it again but got a better look at it. It's like a white centipede looking thing. Also as I was looking for that I noticed little curdled up thing that were under my floor coral that favor pinhead sized shrimp. Any idea what these things could be because I definitely didn't purchase them.

In the first picture I see a type of Bristleworm commonly called a Fire Worm. It's a beneficial detrivores meaning it will clean up scraps of food. Don't touch it with bare hands though because the bristles you see are not legs, they are little slivers that can stick into your skin.

I can't make out anything in the second picture.

They can in the rock you purchased.
