Advice on Zebra millipede care?
I've got 4 lovely Zebra millipedes but I can't find much information about their care at all! I've been told to keep them in a fairly warm room which is usually ~20°C but I'm tempted to get a heat mat. I do mist them every evening to get the soil pretty wet on top. I was also given a reptile substrate when I bought them which after a Google looks like Coco coir but I couldn't be sure. They've also got some bark and leftover fruits and veggies and more leaf substrate on the way.
Behaviour under these conditions is varying a lot - one is out and about pretty often, another sleeps on top of the soil and will have a wander every now and then, and the other 2 buried themselves on the day I got them (2 weeks ago) and I've not seen them since 😭
Anyone any idea if I'm doing the right thing?
