Sea Urchin ID needed?

[Micro-Reefs Aquarium]

Finally got a short video on this hitchhiker, is he had? Can he stay or do I need to get him out? He is tiny and hides in a rock cave and only comes out sometimes.

Looks like your run of the mill pencil urchin to me

+1 Pencil Urchin. I have a couple of them. Careful they will eat your coralline algae.

+1 it looks like a pencil urchin to me as well. I have one in my reef tank and they are a great addition to a clean up crew!

I like your response and feel at ease he not a bad guy say like dinoflagellates which I am fighting in my other two systems.

I got a night view on him when he didn't suspect I had a led spotlight.

Wow, I love how much life is on your rock! Where did you get your rocks from?

They are for sure not reef safe. Had one plow over some shrooms. They will eat anything in their path.

He is tiny but he is eating my purple coraline algae as that is what they do. I am just not the ocean with tons to spare, so I am going to see if I can take him to the LFS and give him away for free.
