Hi guys.
Can you please identify these two crabs for me?

Big one looks like a porcelain crab but not sure about the smaller one.

I’m not sure maybe porcelain crab

Any clue on the smaller one?
Assuming big one can go into display tank and sump the little guy until I’m sure what it actually is?

Do both of them have antennas?

Those are both porcelain crabs - safe.

3 pairs of walking legs, a pair of cleaning appendages (stored under the body), and a pair of large claws.

A cleared picture of both.

So with the antennas and legs yes those are Porcellanidae.
tropical eastern Pacific from Mexico to Peru, the western Atlantic from North Carolina to southern Brazil, and the eastern Atlantic from Senegal to Angola.

If you have a nem, those will go great with one

Still have a couple of mantis shrimp in the tank that came with TBS rock. Will need to rehome them first or the little one is gonna end up being food.

Will setup some bottle traps over the weekend.

Maybe you can trade them into a local reef store for credit you might get a decent amount

Will take one for the sump myself and the rest once caught will be free to good homes for people that want them as pets, like the octopus I found.

Firmly believe in supporting the reefing community and paying it forward.

Great pics - in this case, they're both part of the Petrolisthes galathinus complex. The little one seems to be Petrolisthes rosariensis; the big one doesn't seem to match any species in the complex perfectly, so I'd guess it may be a hybrid specimen (but I could be wrong).
