Hi everyone, I juat got 2 different species of millipedes. Are millipedes able to live together with different types of millipedes in general? Also they came earlier than I expected and ı will be able to get their terrarium in like 2 days. For now they are all together( 2 spirostreptus and 3 other type) in a glass jar with ventilation and little substrate. Will they have a problem for 2 days in this situation? Thanks for any advice. Also what kind of substrate should I use?
