Busy at night

I managed to record 2 elusive inhabitants of my tank. 3Pretty cool how to see the hitchhikers coming out after the main lights turned off.

What was that?

First one a pistol shrimp?

1st was a pistol, 2nd either a really large peanut worm or eunicid type worm?

Yes, it is a pistol shrimp in the first video. I had to wait some good minutes without moving an inch to finally have it come out.

Should I worry about that worm? I didn't see it bothering the mushrooms and the zoas from that rock. And it didn't try to catch the mysis shrimps that were swarming around its mouth.

Thanks for the link. The closest looking picture says it is a Sipunculid. That is deemed safe.
