Found this crab In my mangrove tub today. I'm thinking it could either be a Portunus pelagicus (flower crab) or a form of a pithos crab which i added 3 of but don't believe they were this color.
All the rock in this tub was dry at one point in time. Only thing I've added was some mangrove pods. And some rock from a tank tear down but I asked the guy I got it from and he said it was dry rock. And just a few frags but doesn't remember seeing thos.
