Weird rock boring worm? Please help ID

[ahiggins]

@Lionfish Lair i need your help!!
Bought this wild zoa branch from the lfs last week and this worm thing evidently made it through coral rx. What is it!?
It has some stripes, super light sensitive. I had to wait and only use flash. It also has like a weird mouth part. Like a leech...
Do I need to frag the branch so I can get it out?
It's in the baby rock nem tank.

It's a peanut worm I am pretty sure. Not my image.

I was just reading up on them actually. I think you're right. Glad to know it's not a baddie lol

Ummm the leech mouth is creepy but if he's a good worm then I guess he's cute? Hahaha

It's absolutely a peanut worm. They are great algae eaters. I call mine the greatest lawnmower in my tank because he keeps the rocks stripped of algae. He has learned that there are no fish or crabs to get him so he often comes out during the day. When I first got the coral rock he lives in, I shined a flashlight into the tank after lights out & I've never seen something with no fins or feet move so fast to hide, in my life. He looked like a flying stomach going warp speed into his bolt hole. I laugh to this day with that image in my head. He is a good addition to your tank.
