This forum welcomes Storeia dekayi and has plenty of threads related to them. We also have a S. dekayi expert on the forum "infernalis" who is a moderator.
The small pale worms found in the soil are great for these snake along with smaller night crawlers or night crawler chunks and common garden slugs. Some dekayis have also taken extra small pinkies. Hopefully, Wayne(infernalis) will be by and address your post.
