I've got a young mexican boa right now in a 20L tank with a 50w red bulb for heating, which i've been running 24/7. I just got a leopard gecko too, which i heard a night time drop in temp is good, so i hooked the leos heat up to the timer that my bearded dragon's lights are on. I am wondering if I should do the same for the Boa. Its 2 months old, about 1 ft long and an inch or two. My room temperature never drops below 68-70. Its actually about 75 right now cause all the heat in the house rises to my room.
