I am new to this site and didn't see this thread already so I added it. I will soon be getting a leopard gecko just as a pet in a 20-gallon long terrarium. I have heard that I can house 2 leopard geckos in this. I don't want to breed any leopard geckos so I will just be looking for a healthy leopard gecko at Petsmart. I was just wondering if any of you had any ideas on being able to make sure I get a female at Petsmart so once I am good at taking care of a leopard gecko I can add another female later. Please help!!!!
