CGD or Crested Gecko Diet works for any rhac gecko and even my day gecko seems to love it. It is formulated to be a complete diet and I know it works well for Leachies also. There is also a diet made specifically for Leachies. If you want these you can buy them in quantity and at very good prices from http://www.pangeareptile.com/products.htm. I feed all of my geckos this diet and also feed them roaches.
