Help: Crab ID

[Kdocimo90]

I have these blue crabs that were sold as "blue porcelain crabs" but clearly are not. they are sort of spider-ey and burrow/dig themselves into the sand.

Any way to take a pic without all the blue lights?

 

[Kdocimo90]

I've been told they may be some type of blue sand/mud crab, but can't find much information about them

When in doubt, take it out!

Never seen one yet, I wouldn't leave it in my reef tho, I would toss it in the sump until I knew for sure. I'm def interested on finding an ID, I'll do some looking too
