I just got my newest little guy yesterday and shes a juvenile about 5 inches long with about ten inches of bioactive dirt at the moment. I want to upgrade her in the next few months but im not sure if I should get a tank big enough for her full grown size or if I should get another intermediate setup and move her later. For the life of me I could not get a straight answer on how fast shes going to grow. Also any advice on keeping her happy would be great its my first time owning this milipede type.
