I wish you well with them, you will not be disappointed, that I know. They are really easy to care for, just, as you indicated, not a whole lot out there on them. Although not the best, the GGA Gecko publication (newest one) has the second half of Nephrus in it and it does cover milli, the only thing in print that I know of. Substrate 50/50 CaCO3/bedabeast. Rhachy temps. Moister than other Nephrus, more like Oedura conditions...
Beware they walk around like a drunken sailor and are given to falling over their own feet. I have not seen this in any other gek species. They are not the most intrepid hunters, so crix with rear legs removed makes life easier for them. Wet hide box is a must. Mine eats crix, mealies and zophobas, not picky eaters like cresteds. VERY friendly, handle well, but a bit fragile, spindley legs and all that, plus the balance thing, but seem to like being out and about. Put pics up on the WEB site so go there for more and contact me privatly for more info. Best of luck I am envious...
