Hiya buddy, how's it going, that's a very nice looking snake you got there , firstly everyone has been in your situation at somepoint so we all know how confusing it can be at first, so I'll try my best to help you now, first things first, firstly I find and prefer wooden vivariums, I find that they are easier to heat and keeps temps right than glass which seems to lose heat quicker, just my opinion, others may disagree , so if you have the cash I'd get him a nice small Viv and fill it with plenty of hides as royals like it cramped they feel more secure, next you may want to get a log or two for him to climb as they seem to love to climb, just don't make it too high as they are a heavy bodied snake and could hurt them selves from a too high of a drop, and put a lot of plants in if you are keeping the glass tank to hide up the sides and back of the tank, this will also make him feel more secure , as the last thing you want is a stressed out snake that won't eat, now substrate and heating: you can typically use anything. From paper towels to aspen to reptile carpet which you have, I personally prefer aspen as it's easier to clean and maintain, it looks more natural and holds humidity better, for the heat source use a heat mat, now I'm 100% sure if you can put a heat mat under a glass tank like yours as the weight could damage it so I'd personally put the heat mat in the tank on one side under the substrate and this is a MUST connect your heat mat to a thermastat and put the probe over the heat mat on top of the substrate to prevent it from over and under heating, you typically want your heat mat covering a quarter to a third of your tank but no more than half so that the snake can regulate his temps, now the cool side of your tank proving your house isn't freezing should naturally be around the 80's which is fine, they need an ambient air temp at this, typically room temp, as for a bulb I wouldn't put one on this setup as you would have to buy another thermostat to regulate the bulbs heat and it'll just start getting confusing, this being said you could always use led strip lights, this is what I use as they give of no heat, and come in a variety of colours, also always make sure your snake has access to clean water and your all good to go, don't worry about humidity most people including me only spray them or use moss when they are shedding as if you over humidify them it can lead to illness and respiritry infections. Hope this quick guide was helpful, just let me know if you need anymore help or assistance Tim
