I have a small crab that surprised me today and was molting. I isolated it in the 10 gal. tank. I have a larger that seems VERY interested in other shells. Now I'm worrying he's about to go into a molt also. On top of that I have a small one in there who doesn't seem like he is. Question...can I isolate two molters together. The one who surprised me today has shed it's exoskelton and is inside original shell. You can see it's claw and is pink. I've left him alone. What do I do if the large one starts molting...UGH. So much excitement. THanks for any advice.
