Thanks I'll have to definitely read more into detail about the specifics. Oh, I was also wondering, is a 20 gallon tank big enough for my two garter snakes you think? I use newspaper for bedding, but I have a lot of flat rocks I use and make caves with them and a log hiding place, a big reptile soaking bowl and sticks and three fake plants :P I'm always worried they're gonna get bored) haha. Oh, and a half of coconut they absolutely love to curl up in! haha. Also, should I use a basking lamp? I use one but I'm wondering if it's required, or should I just get a regular like, fish tank lighting source? Sorry for so many questions!
