Oh... I think they're all indo-pacific... again, may be wrong on that.Eek, forgot to add he's from TBS live rock -- so Gulf of Mexico -- if that helps either support or contradict the Tetralia coral crab ID?
Until you can be 100% sure I would keep it in your sump. Not worth risking any coral for a crab IMOback at maybe good, maybe bad, maybe my first official Sump Creature?
There's no coral in the tank yet, but wouldn't want to chance it over one 1/2" crab from hell who could demolish it all before I could catch him again
Not convinced by that... the porcelain crabs we see in the hobby normally either have a white outline on each part of the body, or are striped or with clear, defined spots. This has none of those. Additionally porcelain crabs are flattened, with claws having a wide, flat lateral profile. Again this doesn't appear to have either of those features. Below is a pic of a porcelain crab vs a Tetralia crab for reference.It is a porcelain crab. It should not give you any problems.
Er... as do most crabs... 8 limbs, with two being pincers...Agree with porcelain, it has 6 legs

This threw me off too. Not convinced it's porcelain.Er... as do most crabs... 8 limbs, with two being pincers...
More the reason to tell the OP it might be a porcelain and keep in the sump.The porcelain carbs offered to sell are often of the two patterns as you describe, but there are “uglier” varieties. Also the shape of carapace is a good indication, true crabs are wider than porcelain crabs. However your crab looks a juvenile so hard to tell. If you see it regenerates more legs in the future we know it’s not a porcelain
All crabs are bad crabs!
