Help with crabs

[cocoacf]

So, for some reason, my cleaner shrimp killed my hermit crab during its molt. So now I'm looking to get a new one.
I have a 14g biocube, and I'm looking for a different type of crab than a hermit. I'd really like to get a crab without a shell. I don't know which ones are and aren't compatible with corals though. I've heard that normal crabs can mess them up.
Which crab do you guys think would be best? What about a boxing crab?

Hiya,
You could get an emerald crab, or a boxing crab. They're kinda hard to find, but they're really kewl. There's also an anenome crab which is harmless and pretty.

Emerald.
I love mine, they're awesome to watch. When I feed my tank they just run and jump off the rocks to get to the pellets.

Emeralds are pretty cool.
