Your setup sounds like a good start I've got a few suggestions. You may need to use water with tannic acid eventually if the snakes develop skin blisters. Brewed tea works well for this purpose. Also, I'd provide a 60 watt dome basking lamp over one end of the cage in order to create a vertical temperature gradient. The snake may never come out and bask but it will need to travel up and down the substrate column to properly thermoregulate. I'd give the snake access to a completely dry area of the cage so it can escape wet substrate should it choose to. Also, a deep water container with constantly clean water wouldn't be a bad idea and it could double as a feeding container.
The seller's claim that the snakes are eating minnows is dubious. The two hatchling Muds I've kept would only take small Hylids or Ranid tadpoles. Good luck finding food for them after they hit the 20" mark. I hope you've got a good supply of Amphiumas and Sirens.
Let us know how they do for you. There is still a lot to be learned about Farancia in captivity.
