I had a couple that big from TBS rock a couple years ago. Mine were in a tank for about a year and would come running out of the rocks to take food directly from tweezers.

Out of curiosity - since I also recently got TBS rock which is loaded with gorilla crabs - what damage did they do in the tank up until their demise?

This one has been eating my acans and pulled one I had sitting on the gravel into his cave and was eating on it. I have not put any live rock in my tank from setting it up so he has to have been in the tank for a long while and I have had many acans recede and die over the years. I have also heard when they get big they can even catch small fish. Crabs cant be trusted in a reef aquarium. I am not aware of any other damage he might have done but I did not know he was in my tank until recently.

The fish are staring at me with hungry eyes.

I rather like crabs and I am keeping a few.
These are molts I picked out of the system.
These guys are in my sump and refugium now.
Not reef safe. Will eat fish.

I have a porcelain crab that has long feelers like a shrimp.
