Should I mist the spot where hes buried, or do anything else?
The best advice for dealing with a buried crab is to leave it alone. Note the date your crab buried itself. If it has not surfaced after about four weeks, you can carefully brush back the sand on the crab and make sure it is still alive. If the crab is still alive and appears to have molted, carefully cover it back up with substrate. On the other hand, if you smell a nauseating odor of rotting fish, it means the crab has died, and you should dig up the corpse and dispose of it. To be sanitary, you may just want to scoop the dead crab up along with the sand it was buried in, and dispose of all of it at once. That way, you won’t have the worry of any of your healthy crabs ‘catching’ whatever was possibly ailing the dead crab.
