I have obtained a 40 gallon breeder tank, and am in the proccess of setting it up... however, I have run into some confusion. When I look at the guides, I see the T10 UVB bulbs being recommended. However, on more recent posts in the same threads, I see T5 bulbs being recommended, along with the recommendation to simply mount said bulb on top of the enclosure, above the mesh, which the guides have told me was basically forbidden since the mesh cuts the light reaching the animal by up to 50%. So, which is the correct method? T10 inside the cage? Or T5 on top of the cage?
