HCA: Hermit Crab Association

Okay as i posted before on one of my previous disscussions I posted was about my new tank. So yesterday I got my new tank ready. I chose to use EE and play sand. I put all three of my crabs in. Hedron who is a male, ping pong ball size, fancy who is unknownd about the size of quarter, and babydoll who is female and small, nikel to quarter size. After a few minutes they were all exploring and having a good time. Last night before going to work(I work graveyards) Fancy was hidden, he/she had burried themself. Hedron was still out crawling around in the EE. and Babydoll was resting by the fresh water dish. This morning when I got home. I can see the top of babydoll's spotted shell in the EE, and the top of Hedrons chocolate brown shel in the sand. I checked the temp and my humidity guage, it was all optimum. Hedron is the most active, baby is shy but she comes out a lot and is always in the salt water(as of late), Fancy is really shy. It is very seldom that he is out. When he is its usually to ta. ke a dip or to eat, he's been chowing down lately. These are all the reasons why I think they may be molting, especially with the new bigger tank with deeper substrate. Should I be worried or leave them be and assume that they are molting?

They may just be digging down to test out the new substrate, or they could be molting. As long as the conditions are all good I'd leave them alone.

When I woke up today, hedron had dug out of his hole and was sitting by the food bowl and I can still see the top of baby dolls shell, but fancy is hidden. My humidity is running high. should I open the lid a little bit?

Fancy finally showed up today. SO he was burried for about 2 days. Hedron has dug a hole but isn't covered up, and Babydoll hasn't been very active. So just testing it out then?
