Sooooo cute I think they are indeed dekay´s but Im not snake expert. If they prove to be dekays dont forget to go get some nice small earthworms and slugs
They should accept worms just as readily as slugs, and they're usually easy to find. Just make sure you don't collect them from areas with lots of pesticides, and don't buy bait worms. Other than that, these guys are easy-peasy. Just make sure you dont smoosh 'em, theyre so tiny!
