Creepy Crab ID Please
 

It amazes me that I have had my tank for a year and a half and I suddenly see this furry brown and black crab in my rocks that I have never seen before. I can't get a photo of him because he just looks like the rocks. He is brown with black claws and kind of fuzzy. I have done some searches but can't find any that look like that. Anyone know what it is? Is he good or bad?

Extermination is the only option....Nothing that walks on legs is welcome in my tank... including shrimp.

if its a crab, its generally bad, unless it doesnt have normal claws (porcelain crab, emerald crab, pompom crab)

.

Similar but it has solid black claws and its body is fuzzy. Similar looking and size of an emerald crab. I`ll try and get a picture later when someone is home to hold the flashlight.

He is evil looking!! Not right colour. More solid brown with black claws.

Sounds like it could be a Mithrax crab. Some say Mithrax are safe but I personally don't like or trust any crabs... :razz:

Yup, I think that you are the winner!! Are Emerald crabs and Mithrax crabs the same then. Do they change colour because I did have an Emerald but hadn't seen it in ages and thought it died. This one is a different colour though. Same crab maybe?

hippo crab?
