Good luck getting a pair. Females are especially hard to come by. They are very different gex, really friendly, quite unsteady on their feet, just rather bizarre, but they are from Oz...
You will want to set them up differently from other Nephrus. I have found them to like a much wetter environment. I use a 50/50 mix of sand and potting soil and keep it moist. When I originally started with them I was told to set up like a Leopard gek, it did not work out real well, much too dry. After moving to a wetter environment things were much better. I have not seen much out there regarding care and have generally had to "wing it", so to speak.
Although they look rather fragile, they are tough little ones, cute as all get out too...
