My cage is to dark. I have bobbers in a exo terra screen enclosure. Can't remember size but it's big. the cage is in a corner that is pretty dark. Can't really move him cuz thats the only place with plug ins. i have a basking spot lamp (75 watt by exo terra) that is pretty much all he gets for light. I could put him in front of a window for light but i'm scared of drafts. I can't take him outside cuz it's winter. Any ideas?
