I just got two Leopard Geckos, a male and a female. They're in a 20 gallon long tank with a metal screen cover. I know they're nocturnal, and when I shut off their light (a Reptisun 10.0 UVB) during dusk, they become active at this time, feeding on mealworms and crickets. I'd like to have some light on them so I can see what they're doing. Is there a certain color light of low intensity I can use that won't make them seek their shelters?
I also need a good book on Leopard Geckos.
Thanks for any advice you might have.
