Type of urchin?

[Steven Rothaupt]

This guy must have come in on a some live rock I got. Thinking it is a type of urchin, if so what kind?

Thanks

Appears to be a pincushion. It likes to carry things around as camouflage

Nice hitch hiker/ good algae eater. You may want to provide some algae for him to eat since the tank seems new

Yes new setup. Tank has been going for just short of two months. My friend had dry rock that I put in and I got some live rock to help the system speed up about 3 weeks ago. I only have 2 clowns and now this guy. First time seeing him in 3 weeks. I will look into how to feed. Thank you!
