Is this a gorilla crab?

[Kilman805]

I’m hunting for a mantis shrimp and pulled out a chunk of rock. This guy came with it. Is it a gorilla crab? I intentionally added a few ruby mithrax crabs, but pretty sure this guy is a hitchhiker. He has distinctive black tipped claws.
Meanwhile, I have the rock in a bucket of water. I’m pretty sure the mantis shrimp is burrowed in a hole. I’m trying to bait him out with a chunk of raw shrimp. Any other tips?

Yup trouble maker.

Mantis in rock. Nasty nasty player.

Me, I’d turn up he heat on the nasty critter if I’m not keeping the rock, or the mantis.

Good for you if you got him. Mine took out three fish before destroyed.

 

[TrottingReef]

Yeah that's a bad guy for sure. Not sure what you can do to entice the mantis.

 

[Kilman805]

Thanks for confirming the gorilla.

I confirmed that the mantis shrimp is in the rock. He’s poked out his ugly little green head a few times but is too smart to come out.

There’s another crab on the rock, but pretty certain this is one of the ruby mithrax crabs. Can you please confirm?

Looks right

Congrats at isolating that mantis-beast.
I removed every single crab 6 years ago now and I am so glad I did! I trust not one.
Mysterious disappearances stopped.
Everyone out and about.
Can’t think of the value crabs have in mixed reefs.
Did nothing positive in my systems…..so fired…

Yeah the mantis and gorilla are hitchhikers from the TBS live rock and are just one downside that come with the benefits. But I kind of regret adding the mithrax crabs intentionally. I’ll always eye them with suspicion but I’ll give them a try with the mantis out.

 

[TrottingReef]

I like Mithrax. But 100% agree about mantis. Those guys are not safe with much.

Ya black tips on claws means no good

 

[Kilman805]

Success! I caught him while he was roaming outside the rock and just pulled out the rock fast.

Now he’s alone in my quarantine tank. Anyone want a green mantis shrimp?

These are the only crabs I tolerate. Also TBS Live Rock Hitchhikers. Porcelain Crabs.

My ruby started getting a taste for corals, he was double this size. Had to re-home him.

What about small hermits?

How are you keeping multiple porcelain crabs next to each other?
I thought you had to keep them either by themselves or in a mated pair!

I have six in my 25 gallon. Never had any problems...

Maybe it's the type you have?
I know there are 2 different types of porcelain crabs, maybe 1 is more peaceful than the other?
Do you know their scientific name?

No, but they are from the Gulf of America. Tampa Bay Saltwater live rock hitchhikers.

Excuse me but I believe the correct name is the Gulf of Dr. D.

I enjoy two stone crabs I can’t get out, I’ve caught or killed 20 gorillas too. Still have about 5-7 that I can’t get to. I’m seriously entertaining catching as many crabs as I can and doing an interceptor treatment. I’ll have to repopulate pods and the alike. But, I don’t think I can let these things get to a point of creating tangsuey.
