Great looking jungle Das. They're fun snakes to keep. They usually hit their color peaks at around 2 so the yellow should get brighter and the black should get darker and richer. A vertical or horizontal temperature gradient will work. I have a bit of both for my carpets. I use IR heat bulbs for their basking spots and I also have uths on the enclosure floors. I could probably nix the uths during the summer. I'll be switching to rhps soon because I think they're the most efficient heat source. Keep us updated as your jungle grows.![]()
