Yeah I was going to stick with mostly snakes that I do know for the breeding chondros and the larger snakes I would buy from a reputible breeder as a special order or just keep one or 2 in stock to show what kind of animals I do have to offer I wouldn't keep every different morph but a good variety especially of the corns and kings and even some balls.
I have had success in breeding crickets before but I have never tried roaches.
