Hey, your from mi too! Do you go to the monthly expo in Taylor? If not you should check it out!
Ok, first off, go to varanustalk.com and savannahmonitor.net they are the two sites with the best info on savs.
Heres a quick rundown of a GOOD enclosure at bare absolute minimums. (Don't trust really anything on YouTube or anything at all that says dog/puppy tame).
Heat: 125 degree farenheit basking spot at the bare minimum. (Mine are at 152-155.
humidity: 60% above ground 90-100% underground.
substrate: this is UBER important. 2 feet at LEAST of deep sandy bio-active dirt. Top soil and sand mixed at about 8:2 mostly topsoil.
tank size: 8x4x4 foot bare minimum for 1 adult(just put the baby in an adult tank, don't worry about it getting lost etc.) made out of plywood and sealed very well on the inside. You can also make a "box" to sit on top of a stock tank filled with dirt. The more room, the better.
Also, regardless of what anyone says, these guys are jerks. Anyone who says they "fall asleep on me" etc, keep them too cold. They can get used to you, but they should always have a jerk attitude.
