Hey guys, I'm really torn about the T8. I might just be overthinking it.

I want one for my jungle carpet python. He's 2 years old and a bit over 4 feet, and he's in an exo terra the size of a 40 gallon breeder (36x18x18 I believe?). A T8 would give him more room, but less height. Is that okay for him? Is it better to go up to the T10 for him, or is the T8 just fine?

Thanks!
