Is this Sea Urchin reef safe?

[JFish180]

I recently found this urchin hiding in the rock work of a coral I just purchased. Does anyone know if this urchin is reef safe? Should I let it in my reef tank?

i believe most urchins are reef safe... they just knock stuff over cause they're bulky..

It probably was a hitchiker on a rock with macro on it. I know that my two urchins are bulldozers. But they really take care of the algae on the glass, and although they eat the coraline, for some reason, the coraline spreads nicely.
