The glass trick works very well.

Unless you have hermits in your tank like I do then you end up with a bunch of ****ed off hermits in a ball at the bottom of the glass like I did .

Just hunt through your tank late at night with a flashlight ( would be better if the flashlight had a red lense on it ) and grab him if you see him. Thats how I caught my little guy.

Good luck

Yes the hermit thing will be an issue. I may have to try this over a series of nights until I get the right guy. I have a flashlight with a red lense but I have not spotted him yet.

What did you do with your crab?

Pop bottle with holes in the sump or refugium works well if you want to keep him thats what I do.

I could throw him into the refugium I suppose. The refugium in my AIO tank is vertical ~1 G with a live sand bottom. Not sure that he would have enough to eat there.

Are they in crab heaven or in the chowder?

He would eat your pods. In your case you would be better off taking him to your local LFS. Or to someone that need trigger food.

4 are dead and 1 went into the sump and is now about 2" across and living in a large moonsnail shell, he is my kids favorite part of my tank i think because he is black with red eyes.

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?
