Do I leave them alone? I can't see Moondo where he has dug under, but there is no odor. I've been putting the divider in at night or if we're gone. I don't know, just worried. Should I iso Mr. Shelly? I'm not messing with Moondo. He was living in less than great conditions at Petsmart.
Do you offer any form of proteins: fish, chicken, beef, etc?
Offering fish proteins when you suspect that you have a molter should help reduce the urge to eat the molter.
If you are worried or notice that your other guy is digging around where you molter is, it's a good idea to keep him isoed or place a barrier around the molter by using a 2L soda bottle cut to make a fence. Still place fresh foods and waters in for the molter.
You can also use old tupperware to create the barrier
Here are some more nutrition tips for pre and post molters:

What to Feed Pre-Molt Land Hermit Crabs
It is important to feed pre-molt hermit crabs foods rich in different nutrients. Protein and calcium are two of the most important nutrients you can feed your land hermit crabs when they are pre-molt.
Some people have noted that oils help land hermit crabs shed their exoskeleton. Feeding different oils (coconut, red palm, or olive) can be beneficial to a pre-molt hermit crab.
What to Feed Post-Molt Land Hermit Crabs
Post-molt land hermit crabs should be fed a various diet with foods rich in different vitamins and other beneficial nutrients. You should try to feed the healthiest foods to your post-molt crabs for a week or two in order to have them regain their nutrient levels and they start to metabolize food easier.
Our crab (Mr. Cutie Pottie Shelly, named by our 4 year old) had a successful molt with us while I had no clue what was going on...I actually thought he had died 
So, around a month ago, we got a new crab friend for him, Moondo (named by our 3 year old). Mr. Shelly didn't like Moondo very much. Kept trying to take his shell. I put a plastic divider in the tank to separate them at night or when we weren't home. After about a week, Mr. Shelly learned how to scale the divider to be with Moondo and they have gotten along wonderfully ever since. About 5 days ago, Moondo drug a new shell in the coconut hut and dug under. The coconut hut is where he and Mr. Shelly were spending all their time. Mr. Shelly left the hut for a few days, but the last couple of nights, he has been trying to dig around the hut and seems aggressive again. I'm assuming Moondo is either destressing or molting. My concern is that Mr. Shelly will hurt him if he is molting. Do I leave them alone? I can't see Moondo where he has dug under, but there is no odor. I've been putting the divider in at night or if we're gone. I don't know, just worried. Should I iso Mr. Shelly? I'm not messing with Moondo. He was living in less than great conditions at Petsmart. Sorry for the long drawn out question. Thanks for your help!!
