Firstly i dont know if the wood would help with the heat, it might..... but would be great for the snakes security.
I have a Glass enclosure, i have put a nice background for fishtanks that i bought form the petshop, and its stuck on the back. My enclosure is only 2x2x1 and my snake will live in it for the rest of its life.
Kathy, you wont be able to keep a stimmi in that 3foot fishtank until it is almost full grown... IMO.
If you kept a small young snake in a enclosure that big, it would feel very vunrable, and most likely go into stress mode, and not eat for you.... so yea there are problems with having a enclosure that is too big....
Snakes dont get bored
if you look around this site, you will see most people keeping young snakes in click/clack containers.... this is the best option if u want to keep your snake happy and healthy.
You may think is cruel to have them in such small enclosures, but its exactly the opposite.... i know what you are thinking tho, because i had to question it too, when i first got my snake.
anyway hope that helps.
cheers
