I figured I would post this as I had the other thread about people posting pics about their tanks. Elvira obliged with fully stretching out in her tank today.
I know that snakes don't grow to the size of the tank like goldfish(popular myth amoungst newbies) but I do think they do have a growth spurt upon going into a bigger tank.
Thant's what seems to have happened with Tempo and Jally anyway
I think her spurt came from the better food and more regular feedings she is getting than when she was with her prior owners. That and they kept her in a large rubbermaid tub and that was it. She had to learn how to climb when we put her in this one, now she loves going up and down her tree.
