Crested geckos are extremely easy to keep and breed. In fact, in my opinion they are as simple to reproduce as leopard geckos, just different.
I setup my adults seperately in 10 gallon tanks, although they would do good in something larger as well. I keep the enclosures simple: paper towel, cork bark for climbing, hide box, water bowl. The females have a nest box with moist sphagnum moss inside. I feed mostly crickets, and supplement accordingly with calcium or vitamins. I do offer peach or apricot baby food once a week. I give their cage a good misting 3 times a week.
I introduce the male for breeding into the females cage, leaving him in for a week or so. You will probably hear them sqeaking/sqauking at night, which is a good sign. After I remove the male the female will lay eggs a few weeks later, 2 to a clutch. Females will continue to lay every few weeks, and I have found that they do retain sperm. Eggs are setup exactly as leopard gecko eggs and incubated at around 80-82. They hatch 60-70 days later. I keep hatchlings in Sterilite containers exactly as I keep the adults, only I mist them daily.
I think cresteds make an excellent second gecko to work with after leos, they are really cool little guys. Good luck!
