I got a baby leopard gecko exactly one week ago and I haven't seen him eat yet. He is a hatchling and he looks like an average sized baby.
I am feeding him on large calcium dusted mealworms. I have him in a 20 gallon (76 liters) tank with the hot side at about 88-90 degrees Fahrenheit (31-32 °C). So I am pretty sure the heating is not the problem. On 6th day I found that one of the mealworms had been torn in half and I hadn't touched it. So now I am wondering if the mealworms are to big for the baby leopard gecko.
