I'm wondering what type of lighting you all recommend for a garter snake enclosure. I had my T.s. similis in a one of those large ExoTerra front opening tanks with a full spectrum florescent light on top, but had to move them into a Boaphile enclosure with no supplemental lighting due to space restrictions. I've noticed that, since then, my blues have developed more of a greenish color and are not as brilliant as they used to be. Is this a result of loosing the full spectrum light? Or, is this just a natural color change as they get older?

Note: I will be moving them into a large naturalistic glass walled enclosure as soon as I do some rearranging over winter break. I miss seeing my babies out and about and all lit up!
