Nice to have you with us, Cody. First, from the beginning. NO Rosy Red's or Gold fish. They have Thiaminase. Causes B1 problems and will kill you snake.
Night crawlers are good, the kind Walmart sells. They are clearly marked "Night Crawlers" or you can catch your own from your yard as long as pesticides aren't used. NOT Pan fish worms. The pan fish worms are toxic.
Guppies are safe to feed them. Salmon and Tilapia are safe. Stay away from "Product of China"
