I feel ridiculous asking this because I know cohabitation questions are asked a lot. I have an adorable Thai Rainbow millipede and am wanting to get one or two more millipedes to live with her. I’m planning to get an Ivory. I was wondering if it is okay to also house a Spirostreptus Sp. 1 with her as well. I am having a hard time finding info on what their temp and humidity requirements are to figure out if they are the same. I believe they are close enough in size. I’ve got my sweet girl in a 20 gallon enclosure.
