It kind of sounds to me like your little guy just might be more comfortable in the main tank. Are the conditions in both tanks the same? I'm really new to all of this and have never had to isolate a crab for anything, so your whole problem interests me as well.

I know that almost everyone on here agrees that you shouldn't dig up a buried crab no matter what. I have three buried right now, and it is killing me not to dig.
