hi, a couple of days ago i bought a 2 year old corn snake complete with full setup, the snake is fine no problems there but a couple of things worried me abot the(wooden) vivarium. the first thing is that there was a light in the tank that i was told had to be kept on all day, but the light was stuck on loosely with tape and didnt have a guard so i took this out straight away. the second thing is that the heat mat is on the side of the tank, i am not sure if this is ok as the snake cant lie on it to digest its food, any help will be great thanks.
