Hello all! I'm new here and have recently bought a Checkered Garter Snake, I think its a girl but not sure I'll get some pics of her later when I can and maybe someone can help me tell lol.

Anywho I have a question. Yesterday I fed the snake a minnow and she ate it with no problem. Also I have some minnows swimming around in her water bowl, but after I fed her... last night she ate the 3 minnows i had in her water bowl .... so she had 4 fish in one day... is this a good or not?
