I hope this is the appropriate section to post this. I have two giant millipedes who have been hibernating now for about 6 months. They have dug themselves separate caves under the substrate, and I can see them through the glass. They look totally healthy and sometimes I see them moving, so I know they are ok, but for the most part they are always sleeping. I am just wondering if anyone knows if this is normal, and how long might they continue hibernating. Any information is greatly appreciated. Thank you!
