nephrurus milli care question

Hey, lately ive been trying to call breeders of this gecko to see how they keep them..


so far ill have a tank 2 feet long, and 12 inches wide for a pair of them....the substrate will be sand..also i gather i need 2 hide boxes, one on each side? when you say the sand has to be moist and 5 inches high, how is that possible? do you bury the moist box in the sand?and keep the lid on and cut an opening in the top? or do you use side-opening hide boxes

for breeding, whats required, and how do you raise the babies?

does anyone here have a picture of their setup?

thanks,
Mike
