Thank you so much!
I'm thinking about an alternative. Aesthetically, paper towel seems ugly and such a waste of trees haha. I'm a bit of an eco freak when it comes to stuff like that. Which leads me to another question. Can coconut fiber be used for composting when it's done being used? Are there any other safe alternatives you can think of other than this substrate? Is there anyone here that has had horror stories or bad experiences with coconut fiber?
I've tested the light and it seems to heat up very fast. Went up about 10 degrees (to 80 degrees from my room temp.) in less than 5 minutes. Just thought it might be too powerful. Don't wanna bake the guy! I suppose as long as I'm adamant on watching the temp. all will be okay. And I will certainly look into a "night light" for them.
And yes!

I figured they'd need something to grow into. I planned on getting something bigger after a while and then passing this tank down to a different breed.
Thank you so much for all your help! I feel a bit more confident now.
