I would purchase a 20 Gallon Long aquarium for him (Only around $50-$70 in stores and comes with a locking screen.) That should be big enough for the rest of his life.
You need to do a few things to ensure that you have a happy healthy BP.
1. Buy another hide exactly like the one you have now, you need 2 identical hides.
2. Get rid of the Thermometer/Hygrometer gauges, they are useless and most of the time are not accurite.
3. Get a Thermostat. You could end up burning your snake without one. If you don't have much money to spend right now, get a cheap Thermostat like the ReptiTemp 500r. You can find it here for only $25.

It regulates your UTH automatically so it doesn't get too hot. (I tested my 10-20 Gallon Zoo-Med UTH unregulated and it went up to 138.9 degrees before I shut it off. Imagine your snake on that!)
If even that is too much to spend right now, go to a local hardware store and get a dimmer for around $10. The downside is you have to manually tweak it and therefore have to keep a close eye on it all of the time.
4. Go to Wal Mart and get an AcuRite Thermometer/Hygrometer. They are around $15. This will tell you your Humidity, Ambient temperature, as well as your UTH temperature.
6. Get rid of your second UTH and your heat lamp, and just use one UTH with your dimmer/thermostat. Keep adding heat devices one by one until you reach your desired temperatures. The heat lamp sucks up a lot of your humidity.
5. Get rid of the reptile carpet, it harbors bacteria and is hard to clean, expensive too. Go with paper towels, newspaper, or aspen. I prefer aspen since it's still decorative and there is more space in between the UTH and the animal.
And don't be afraid of the little guy, I've never been bitten but I heard they don't hurt. Just be confident, and try not to be too nervous, he can sense that.
I am not an expert by any means but this is what I've learned from BP.net, and I hope it helps!![]()
