Hey, everyone. Like the title alludes to, I've got a leopard gecko who currently is living in a 10 Gal (20x10x12) tank with a screened cover. Lately I've been putting a small desk fan on the top angled in to provide some airflow and ventilation. Is that a bad idea? Could it cause any stress to my gecko? Are there any recommended alternatives? One idea I had was to rig up some old computer case fans to set on top of the cover, but I want to know if it's even a good idea to try. Thanks in advance.
