I have a Sierra Garter. It's wild caught, and would normally thrive on a diet consisting solely of fish and amphibians. I would really like to be able to offer her a variety of foods, as I know guppies and Danios aren't going to be enough.

She will most likely not switch to pinkies, and that's fine by me. But I would like to offer her a variety of amphibians as a supplement to her diet. So...what would you recommend? What are some amphibians that I could feed to her without worrying about poisoning?

Thanks for any input!
