Giant crab VS Mantis shrimp would be a viral video

There are a number of these videos on youtube. The mantis always wins.

Personally it looks like a emerald to me. Those claws are not shiny, black, or pointy. They look like something which would pry pieces of algae or scrape. If nothing is damaged so far I'd let it ride but watch. After all, you just noticed and caught it.

If you are unsure, and have a spot to put the detained (interesting choice of wording by the way, made me giggle) then do that. Can always watch them in there while in detention

Edit: Emerald crabs typically have orange or red on their main claws arms. You can do a search and verify / compare.

I don't trust any crab with one exception, the Scarlet legged hermit. Even the so called "safe" xanthid crabs aren't safe.

I think the acropora and porcelain crabs are safe from what I've read.

Did you know that the xanthid crabs are poisonous? Yep they carry palytoxin. Also they can and will eat live fish and corals.

I decided to change my post, but I also want to add that you should get rid of it. IMO

+1. I hate crabs they kill everything. When my emerald got big and started attacking my fish and killing my snails, I introduced it to my white ceramic fish tank.
