ok well i got a new corn snake on monday, hes not in his viv yet but there are a few questions id like to ask. firstly the viv i bought off the rbeeder had the heat mat inside the viv (is that safe) i guess there is no other way for the heat mat to work seeing as the base is half an inch thick wood. also there is a socket for a lamp above where the heat mat is. do i need a heat lamp aswell? because i want a light so i can see my snake. but i dont know what to get. any suggestions?
