I first got my snake about 2 years ago (last, last may) and she was my first snake. The people at the reptile show I got her from told me that she needed a basking light and that was it. I have heard that UVB is very beneficial for bp's but they can survive without it. She hasn't had UVB since I got her. Should I be worried about it? Should I buy a UVB bar for her? Thanks in advance!
