I have kept and bred both species. The ground skins need more humidity. Their food needs to be much smaller than a 5 lines. Small mealworms, 2 week old crickets, etc. They calm down pretty good but don't take to handling. Clutch size is 2-3 eggs. Babies are very tiny and I found that they needed very high humidity and 2-3 DAY old crickets. It helps the babies to catch the crickets if they are dusted with calcium, minerall, etc. Adults need 2-3 food items a day. Babies 6-10 over 2-3 feedings per day. Babies will bury themselves in the substrate. I simply kept the babies in the hatching boxes. Since both species bask I provided UVB bulbs (chroma 50 in my case). The ground skinks like it a bit cooler than the 5 line. Basking site about 85 degrees. 5 line basking spot about 95 degrees. Room temp on the cool side of the tank. Baby 5 lines will eat massive amounts of baby crickets. 10-20 per meal 2-3 times a day. Very hard to keep up with feeding babies of both species. I trained them to eath small chunks of a cut up adult cricket dangled on a thin piece of copper wire. Both species grow fast. They will breed second season. Female 5 lines do a better job guarding eggs, but I removed all eggs from the females anyway. My colony of 5 lines were around a dozen adults. Clutches 5-6 egg average. If I remember correctly (this was early 90s) the eggs hatched in about 45 days at 80f.
Hope this helps. It's off the top of my head going by memory, so it's a bit sketchy.
