I order crickets from Rainbowmealworms.com. I would not buy anything larger than their 1/4 inch size since he is so young.Ok, that makes it better! Every time he basks he climbs right up and I was worried that he was too cold Thank you so very much! Also, do you know any good places to deliver smaller crickets? Thats the only thing heâll eat and I am running out of small ones.
