Tuxedo Urchin + Hermit Crabs = dead urchin?

[darb]

I added a Tuxedo Urchin to my tank last weekend and it was happily mowing away at all that it came across in my tank. This morning I noticed it was upside down and eaten out ....

My usual suspects are the blasted hermit crabs, does that sound right?

Only other possible creatures are O. clowns, Flame Hawk, 6 Line Wrasse and a Rainfords Goby.

I also just added a star this weekend, will the hermits munch on that also?
