Hard to tell from the picture, but it appears to be

As long as the lines between the spines are blue i'd say thats right

That looks more like a halloween urchin to me, basically the same as a blue tuxedo but grows larger.

What's throwing me off is the orange spines, all the blue tuxedos I have seen have tannish and white-ish spines.

Just make sure your rocks are all stabilized and secure enough that the urchin can push or pull them over. Any loose corals, shells, small rocks, and even hermit crabs will be picked up and moved around as well. They're pretty tough for such a little critter.

I originally did secure the rocks for a goby and all my corals are glued down because the crabs were constantly knocking them over !!
