Crab question

[D1J8Z]

OK so I just found a crab that had to have been in my reef for a long time bc Its a few year old tank and nothing new has been added in a long time

Fortunatly there was no signs of a problem to look for him just kinda found him. He is Black with lightly Hairy Legs and smoothe head big decent sized claws with redish tips so I guess I can rule out Gorilla crab
It almost looks like an emerald crab

Thanks

Dave
