So I recently bought my first baby bearded dragon about two weeks ago. I’ve been trying to get the lighting right and have been conflicted on what to use. I have a 40 gallon tank and for UVB I’m using a 12” reptisun t5 HO 10.0 and I have it mounted in the middle of the of the screen on the inside. I wasn’t sure if I could put it on top of the tank because the top is metal with smaller holes in it and wasn’t sure if enough light would get through. I’ve been considering getting the 22” reptisun but I’m not sure if it will leave my beardie enough room in the tank without uvb. Please help.
