Crab ID needed please

[CountryWellReef]

Hi,

TBS live rock. Need a crab ID. I THINK it's a young stone crab. It has spotted legs though..

Best pics i could get.

I can’t make out much from those pics, but I’ve used TBS rocks before and I think the two likely suspects are Gorilla crabs and Porcelain crabs. Gorilla crabs are said to have claws that look “chocolate dipped” because the tips of their claws are very dark almost black. Gorilla crabs are more active at night, so check after lights out with a flashlight. Gorilla crabs can be terrors and are best relegated to your sump or a dedicated system.

Porcelain crabs are often seen on the underside of rocks, they are filter feeders and you’ll see them waiving their little waivers collecting food all day. Porcelain crabs are reasonably peaceful, welcome hitchhikers.

He's got a couple labeled as TBD crabs, some good and some bad.

When in doubt, sump it until youve found out

Yea I'm going to try to trap him. He's not a Gorilla, he's very smooth, no hair. He makes click sounds. Thought I had a mantis but it's him. Claws are very thick and bulky.

Ill try to get a better Pic if i can't trap him.

Look like this little cutie?
Sorry for the bad news, but it grows into a delicious Florida Stone Crab. These critters make great sump monsters like Fido here. Easy keepers and loads of fun to feed when they grow up.

I just took every piece of rock and all corals out of my 150 Gal. to catch a stone crab. Body is two inches wide and with craws folded three inches wide. Been set up for a year, and we did everything to catch it. We would catch a glimpse once and awhile, get bigger and bigger. Lost a possum wrasse and most of clean up crew
