Hissing Cockroaches as pets + breeding project

I think we have all heard of hissing cockroaches and know many people keep them as pets. What you might not know is that there are over 10 species available as pets! I'm going to try and crossbreed Princisia  Vanwerebeki B+W (tiger Hisser) with G. Oblongonata (giant red Hisser largest available). The goal is offspring with a large body but beautiful white and black striping. Wish me luck!
