Hi everyone,I am new on this website and new to owning a corn snake I have a anerythristic corn snake called simba.He/she is a month old and was sold to me at just over two weeks old from a man whose snakes had 11 hatchlings I think they were sold quite early but he seems fine.Since I've had him he's ate one pinkie and is eating every 5 days,he seems overall a very healthy snake and is very relaxed when being handled.Today I brought a viv that is 3ft by 2ft for £25 from Facebook the man who sold me it told me it had tortoise in it before,simba is in a small terranium for now and has got a heat mat.My questions are how would I place a heat mat in the new viv as it doesn't have a glass bottom where as my current smaller one which the heat mat slides into another question is I don't know when to put simba in his big viv as I've read hatchlings/young snakes can get scared in big vivs.Would a heat light be better than a heat mat for him and if so what lights would you recommend,thank you for any help.
