Hi, my two Apple snails seem to me somewhat inactive lately, eating a lot less. So I got to reading about them more and I found out that apple snails have a hibernation period which usually starts at end of summer/fall and throughout winter. Are you guys experiencing the same with yours? I wanna make sure it is not some illness. They are eating a lot less, most at night and during the summer they would walk all over the place but now they are doing their walking at night and "sleep" almost all day. If hibernation is not the case, what could be the cause of the inactivity?
