    Black & White crab with Red claws

    I have had this little guy come with my live rock. The tank has been up and running around 5 to 6 weeks and he’s still here. Very small and timid. If anyone knows what it is I can’t figure this one out.

    Build Thread Emerald Crab

    Just showing off my Emerald Crab ... mildly aggressive little fart. I typically treat him 2-3 times a week with a small piece of shrimp (frozen raw) tuck to the end of a stick so no surprise he gets excited when he sees a stick!!

    Confirming Emerald Crab (also what’s this black/white hole in the claw?)

    We bought this “emerald crab” today and just want to confirm whether or not it is actually an emerald crab because it is not green like most of the pictures online.
