Hey Dudeeeee. Nice to see you posting here. Welcome to the site
You know my stance on Eco Earth as per the chat last night, haha, but I'll say it again- I'm not a fan. I prefer cypress, myself, but I know people on here do use eco earth. I
think that you could do newspaper or paper towel, and put a water dish under the heat source, so it evaporates, It'll help keep the humidity up. You'll want to cover as much of the screen top as possible, so you can keep the humidity in. Like Hairless said, aquariums are not ideal, an enclosure made for a snake would do you much better. but that's not what you're asking about, i suppose, so aaaaanyway.. lol
There are a LOT of very credible breeders here on RTB, many of the members have dealt with them and can offer you sound advice based on personal experience. No matter what you're looking for, you can find a reputable breeder (probably on here) that will not rip you off, and that you can work with and stay sane (working with pet stores can be a hassle!). I suggest you check around here, and on the classifieds, and also remember the BOI is
your friend. dont be afraid to do resarch and ask around to determine if you're comfortable ordering from a certain breeder.
Umm. that's all i can think of right now, LOL. it's late and my head hurts.
good luck dude.
