Hello everyone. I am new to the forum and to having hermit crabs and I need a little guidance.I have 1 medium (though hes def on the smaller end) purple pincher named Alfonso, who I have had for about 6 weeks, and two small purple pincher's names stripes and swirl.I am pretty sure Alfonso is getting ready to molt. He has been less active, then started digging nice little hole. he came back up for a while and I picked him up to say hi and I saw the back bubble thing they store fat in before a molt. But he has not changed shells yet and he is already too big for the one he is in! Will he go down and molt then switch shells when he realizes he really is to big for it? or is he not quite ready yet and will change shells just before he goes down for molting? Next,I just have sand in my ten gallon and I have about 2 1/2 inches maybe 3. Is that deep enough for him to molt in? He might not be very large but he is definably not in the small category. So far it seems like I need to add more sand. Right now he is about shell deep in the sand. Will I be causing too much stress buy moving him and all his stuff for like and hour to add more sand? I also only have some play sand to add that I borrowed from a friend who's three crabs are staying the winter with me. However it has not been cleaned or baked or anything, is it absolutely necessary that I bake it? My friend put it in her tank with out doing anything to it and everyone is fine. Last, I only have commercial hermit crab food. I am planning on switching to something better from the addiction store, after this runs out because while I have it I might as well use it. While its not great food they can live on it for a while, but from what Ive read Alfonso needs something better esp when he is about to molt. So I gave him what I had on hand. Some honey, peanut butter, banana, scrambled egg, and some egg shell. I don't think anybody touched it, and now I am worried he might not successfully molt because he doesn't have the proper nutrition. Is there something else I can get him that will help him molt?
