hermit crab question

[cholland]

I just recently acquired some new hermit crabs from my dad's tank. He just broke his down and either sold or gave me the stuff. Anyway the crabs he had have red at the end of their appendages, but kindof a blueish gray on the rest of the appendage. They also move their antennae very rapidly, like an insect. And they appear to be very aggressive towards other crabs.
Any idea on what kind these are?
(they are not red leg, their legs are darker)

Probably blue leg hermits. Check them out on this site. They are very good as a clean up crew. I have several in my tank.

nope I have looked at pictures of bluelegs and I have blue legs in my tank now.
These are very distinct. They almost look like something you find wild. But he bought them at a LFS.
