Weird crab with very long arms

[mrkrispy]

I perused this forum and Dr. Ron's article but can't seem to find any info. I have a crab hanging out in acro. It has a tiny head and body, but the front "arms" are very long, completely out of proportion with the body. The pincers on the end of the long arms are a perfect V. Anyone have any ideas?

It is shy but will take food from a syringe when I am feeding the tank...

THanks!

Sounds like a galatheid. Any chance you can take a picture?
