Hitchhiker Crab! Is it Reef Safe? Pics inside!

All the signs point to it being ok other then the fact it looks like its got some thick pinchers. I would still toss it just to be on the safe side. Acro crabs protect the acro from potential predators and vice versa. But theres no facts out there saying the crabs are reef safe. From my experience, no crab is truly reef safe, they are all omnivores and opportunistic feeders.

 

In the sump he stays then!
