Ok please read on before flaming. I have been thoroughly devouring the book "The Leopard Gecko Manual" and im looking to start a 75-100 gallon show tank in my living room, i want to set it up as a naturalistic display. Now in the Book it says that you can successfully house Leo's with Collared lizards, South African flat-lizards, or girdle tailed lizards. I was wondering if anyone here has tried any of these other species and if so what outcomes did you see. I'm trying to read up as much as i can on this before i attempt it, as i would not want to have my Leo's or the other lizards be harmed if its avoidable. Thanks in advance for any information that you can provide, and for referance in the book its on page 26, in the section "other animals" in the "Naturalistic Vivarium Design".
