tarantulas are nocturnal, so i would think a uvb light would bother them. i use a red infrared nightime bulb with my tarantula to create heat and so that i can see her at night.
Well, see the thing is that I have multiple Tarantulas. What I mean is that I don't want to have to buy them all lights. So I am thinking about just mountin it so it points at them all. Well if anyone could put some input on this. Thanks in advance!
