Anyone kept Spider Decorator Crabs?

[Lance M.]

I was wondering if anyone has one or has before. I use to have a regular decorator crab (sponge crab) that would take zoos and put them on it's back to camoflauge itself, it died of old age I guess it was pretty big. But these spider decorators look completely different but do the same thing. Are they reef safe? (Other then the fact that they take polyps, etc.) Anyone with first hand experience?

Edit: I just did Google search and one site says they do eat inverts. And I got to see some more pictures- these things look scary. lol
