Hey the cage looks amazing ZOO quality stuff right there! What you can do is get a green tree python! amazing looking snakes and would work well in that cage.
I see what your getting at but I dont think an ETB or a GTP would make good pets for a beginner. Probably a Jungle or something like that but even they are not that easy I dont think. (I've never had one so I can't really talk) But i just think GTP's and ETB's are very hard or can end up being very hard to care for, if your not ready!
Friendship is like peeing on yourself: everyone can see it, but only you get the warm feeling that it brings.
Why is it called 'after dark' when it really is 'after light'?
