Crab ID please

[Osiris]

Unfortunately i had to bring it out of water for a few secs while i took the pic (sorry crab cake) how sad am i iv named him lol
well im not sure what sort of crab he is all i can tell you is he came in on some LR and in the last 2 weeks he has gotten to just over an inch including legs he was about 10mm ish he is pale green in color and hasnt bothered the 2 clowns but he was hiding under some lava rock which i removed today to put in my 2nd tank so can someone ID him for me? Im hoping he is safe to keep since iv had him for over a month im quite attached to him but will accept what people say.
