I’m new to keeping millipedes, I have only had my tank set up for several weeks now and I have 5 glomeris marginata juveniles and a juvenile bumblebee millipede who seem to be thriving well, however, my first adult giant African millipede died 4 days after bringing him home from the pet store, they replaced, however this one has also passed after 9 days, I’m really not sure what I’m doing wrong as the other guys are lively and doing great. Any help would be greatly appreciated as I’ve always wanted a giant African millipede
