The model that I want does not come with a light shroud. It is undertank heated only. Will my snakes be alright without the light? Is there an alternate way to light the cage (model 221)? Also, how do you keep cages cool, for low temp species? It gets over 80 in my cages easy without any heating devices, and I have seen snakes that prefer to stay in the 70s, so how would I keep them cooler than the others?
