gorilla crab or emerald crab?

[Jhbard]

Bought some live rock had what I thought was a gorilla crab hidden in it but now that it came out of hiding I'm not so sure it's emerald green is it just a gorilla crab or did I actually bring home a baby emerald crab?

Emerald crab

Emerald, for sure or a gorilla crab that murdered an emerald crab and is wearing its carapace as a disguise.

Emerald, for sure

Yay free crab

Still keep an eye on it. I consider emeralds reef safe with caution.

I'm just happy I don't have to kill it I'm going to give it back to the store when it's bigger
