Thank you all for the help, I appreciate it so much!

To clear some things up:

1. I do believe the Thermo-Hyro Digital & Gauge I listed is also thermostat, right? (Lol, I might be wrong but I picked it up thinking it was a digital thermostat and picked up the Gauge as the second thermostat). If they're not, I shall return it and just pick up the basic thermostats they had at the store.

2. I will be exchanging the 5.5 gal tank I have for a 10 gal to accommodate another cave

3. Would I be able to make a cave myself using rocks and glue? (Sorry if this sounds a little stupid, I just want to make it pleasing and would think real rocks = awesome for any snake as a hide out). Plus it would look awesome in the tank :]

4. Would I just be able to plug the UTH into an outlet or is it a requirement to get that control?

5. Since winter is here, should I invest in one of those lamps to keep the tank from getting too cold?

Again, sorry if these are sort of stupid questions, I just thought I'd ask the experts :]
