I have a UVB light on the lid of my tank, and Im wondering if its really needed or not. Ive read a lot of things that say yes and a lot of things that say no. I know that BP's are nocturnal but Ive heard that if you do have a UVB source, what little bit they do get is good for them. Ive also heard that you can use a damp towel on the lid of the cage to keep up the humidity level. If i have the UVB light on the lid of the cage then there is no room for the towel. Whats the best for my BP?
