Is this Sea Urchin reef safe?

[ken6217]

I just purchased this sea urchin and it is in a bucket acclimating. While I was doing that, I tried to do a search on the net. Does anyone know if it is safe for shrimp, snails, sps and lps? I asked the store owner and he said it was a pin cushion sea urchin and it was safe. Upon looking on the net it looks closer to a Long Spine Banded Sea Urchin. If it is that, this was part of the description: "Juveniles generally eat algae, and the adults are carnivores, preying on invertebrates."

Does anyone know of this and know if it is safe to put in my tank? This is a picture I just took of it.

Also known as the "Hatpin Urchin". I bought one about four months ago. It hasn't bothered any of my inverts or corals. It roams the tank eating coralline algae. Essentially harmless, but the customary YMMV disclaimer applies.

knocking down corals by just roaming is what i'd be worried about, not so much the invert thing

it will knock things over unless you use a ton of super glue

Thanks for the comments. He never made it to the tank. He went back to the store.
