Look - Sc. subspinipes mutilans is a tropical rainforest species. On the forest floor in rainforests what do you find? - yes, rotting bark, rotting leaf litter, and then some soil below.Just realise what kind of natural inhabitants centipedes have and try simulate the substrate a bit.
they dont live in bark chips. Anyway noone is trying to make you feel bad or prove you wrong. You can do whatever you like, most opinions are offered as help
