ID This Crab?

[Oscar]

Well I have been trying to capture this hitchhiker crab for the last few weeks using a drikning glass and shrimp meat at night. No luck.

Got my flashlight out last night and discovered his hiding hole. It is a small cave with 2 entrances but he is getting too big to hide completely. If he scurries in one entrance then a couple of his legs show up at the other entrance.

I want to introduce some more inverts to my display tank and I am concerned that I will simply be feeding this crab.

Since he will not come out for the bait I will have to go in after him. I am proposing to pull out that rock, squirt him with fresh water, and hopefully he will drop into an alternate bucket. After that I am not sure what I will do with him.

Maybe set up another tank?
