Welcome, I would advise against small animals in an enclosure containing Nepenthes. I don't know about dart frogs, but wild anoles are eaten by my outdoor Nepenthes.
Anyway, Nepenthes that would do good in there include
N. x Miranda
and hybrids of these. If you can find them, N. x tiveyi and N. x dyeriana would be good, although you should gain experience with easier species and hybrids first.
