Hi:
Care for prarie ringnecks is very similar to Southern ringnecks, but with a slightly drier substrate, from the information that I could obtain.They will take small earthworms, and guppies, although in the wild, these little Diadophis usually take lizards, such as skinks, and small treefrogs, like the Southern ringnecks.
That is exciting that they are available at pet stores. I always wanted a prarie ringneck. It's funny that you posted this. I was thinking about their ventral pattern just today.
