I have a new dragon and she is in a 30 gallon right now…24x24x12. I have a UVB lighting question. Currently using a zilla T8 18” fixture with desert 50 bulb. (Her basking spot is about 7”-8” from the light). I also have a 12” zoo med fixture with a reptisun 5.0 that i am not using. Should I / can I use both? Or is that too much? Not necessary? Thank you! By the way, she just woke up. . .humidity will get down to low 30's soon.
