I was told ages ago and have read many times since then that Pueblan Milksnakes and California Kingsnakes do not require UV lighting because they are nocturnal and would rarely encounter UV light in the wild. I'm considering purchasing a Mexican Black Kingsnake which is also mostly nocturnal. A care sheet I found online claims this species requires full spectrum uv lighting. Another care sheet claims they have no special lighting requirement. I'm inclined to agree with the latter and stick with the under tank heating system I've been using with my other snakes but just to be safe, is there any merit to the first care sheet's claim?
