[VVReef]

Hey guys! Can anyone help me identify this crab? I found it in my tank and moved it to the sump. Friend or foe?

Mosaic Reef Crab? Did you get you live rock or sand from anywhere specific?

Does he appear red, with black tips on his claws? If it does, get it outta there! It looks like they are some kinda bad news.

No! The crab probably came on a piece of coral.

It was identified as Atergatis floridus. It is probably that species. Thanks evryone!

The meat of the crab is toxic, even when cooked. You got yourself a doozey.
