Hi Jason,
I've had a sharp-tail since early July and it has since shed twice and doubled in size, so I'd say that it is doing well. I too could find next to nothing on captive husbandry.
I have my snake set up in a 2.5 gallon tank (the snake is pretty small). I've got about two inches of bed-a-beast on the bottom and a piece of pine bark covers about thwo thirds of the floor. I keep the area under the bark moist and this is where my snake usually hangs out. It has, however, constructed burrows throughout the moist bed-a-beast layer at the bottom of the tank. I keep my snake at room temp with no extra heat. About once a week I collect 20 or so small slugs (about the 3/4ths the diameter of my snake in girth) and fold up a leaf of romain lettuce and put this and the slugs under the bark slab. I've never seen my snake eat, but the slugs disappear and it is growing fast
I have also tried small snails (various species), crickets, mealworms, earthworms, sow-bugs to no avail. Slugs are the only prey my snake seems to take. I use a small condiment cup as a water dish. I've never seen my snake drink from it or seen my snake above ground for that matter. I can tell it does come to the surface at night because it likes to defecate on top of its bark slab and I have also found its sheds hooked on the rough upper surface of the bark.
My sharp-tail is the long-tailed form and was collected up in Santa Cruz. From what I've read the long-tails are found in moister habitats than the short-tailed forms. So if you have short-tails you may want to try a larger enclose so that more of the substrate can dry out.
Keep us posted on your snake. I personally would love to have someone to trade info on this species with.
