my new garter!

[setfree]

I found this large garter snake and brought it home and put it in my prepared aquarium tank. I think it's a female but not 100% sure. it is about to shed so it will look really good soon. After a day it readily accepted 3 or 4 worms. the next day I tried feeding it a large frozen mouse that had been thawed. it did not accept it and only ate worms. any comments on that? anyway the snake is really calm and likes the habitat. here are some pics...
