HCA: Hermit Crab Association

i currently have 5 hermit crabs in a 30 gallon tank, and three of them have gone under, and have been under, for 4 days, some chirping has been going on and one I know for sure is molting, because he dug a hole against the glass and i can see him- no death smell, just curious is this is normal

Yes it is normal for more then one crab to be molting. I currently have three molting at the same time as well. So no worries!

thanks, i was not sure because last time i thought that was happpening a shell stealing fest went on and i found august without a shell
