Welcome, Scott.
Give your snake sometime to get used it its new surroundings and you. If I may suggest. Don't have anything heavy leaning on anything. You may think it could never fall but if it does your snake could be injured or killed.
Any food suggestions are for a garter and since we really don't know what you have, take it with a grain of salt.
Earthworms in dirt. Guppies in a shallow bowl will drive a garter crazy. Hope you can post us a picture. Best of luck.
