I have a colony of dubia roaches that feed my 5 pacmans, 12 tarantulas, and 2 leopard geckos. I primarily feed 90 percent dubia since they cost me so little to keep my colony going. Ill give everything something different once every month or so. I'd go with dubia roaches as staple diet. If be spending hundreds on feeders each month if I used store bought. Never had any problems with any of my specimens. Don't forget to dust em every once in a while with calcium and vitamins.
