 Jerry, Jerry, this is what I did in regards to the Crested Geckos, well actually Jerry and Pete, Jerry and Pete got the $10 Sterillite dumped all the coconut fiber out so I can be more attentive to the general hygiene of the enclosure plus they have a lot more room now. They seem to love the empty large tissue box as a hide. I still have the water reservoir for reptiles, reptiles, food dish. Now this is what I did since the female used to deposit a lot more eggs. Actually all the eggs were deposited in a nesting box and my idea that that she will lay eggs in a very deep substrate of coconut fiber did not work. There were no eggs after all these months so what I did was I took an empty protein powder container which is pretty sizable and I took the 40 watt soldering iron and I burned, I'm not sure if you can see it, I burned a hole at the top on the side as an entrance and exit and I packed this jar down with lots of coconut fiber, constantly adding water and packing it down, adding water, packing it down so I guess it's a source of humidity as well as a nesting box and I deliberately use the translucent one so if there are good eggs in there and they are hatching I could see them in action.
