Quiz -What is shown in the picture

[anglfish]

During my usual 1 hour/day tank watch I found another hitchhiker. Pretty sure it came in with some soft coral I bought the other day. I tried to take a decent pictures for 2 nights but this one seems to be rather shy. It definitely is a crab and I searched the reference section already but was not able to identify yet. It looks similar to the Xanthidae which as a read is bad news.
Here is a description

• 1 1/2 - 2 inches
• smal dark red pinchers, pincher arm seems to be same width then other legs
• striped legs
• flat body
• a bit hairy
• seems to be grazing off the rock
• nocturnal

Here is the best I could get:

Lemme know if you can identify this one.

Thanks,
