..................... The only major issue iv had is keeping the humidity/moisture levels in check. Its very easy for them to get WAY too high if the tubs do not have enough ventilation.Space: Naturalistic enclosures generally are required to be larger than sterile setups. Considering the size of my leopard gecko colony(and the fact that I prefer to house animals singly), I can't really see setting up 50+ aquarium-type cages. I would really love to hear more about how this is working out in a rack system.
......................... For the most part Ive never had much of an issue finding the eggs. My females always tend to nest in the same general area (On or just off of the "hot side", in soil temp gunned in the low to mid 80'sF at a depth of 4"-8") despite having a more "conventional" nest box/humidity hide provided. It never takes more then 5min to dig the eggs up. Hope some of this info helps you out Ted.Breeding: Finding eggs. The biggest issue I see here. Although providing a seperately regulated nesting area is an idea, in tubs using a bulb as a heat source is going to be very difficult. And I really would rather not have to dig up the entire tub just to find eggs for incubation. Although this would be simpler in a single animal setup(you could simply check obviously dug burrows) it's still a bit more complicated than I would like. This is also the issue many people have with cresties in these types of setups, as they will bury eggs just about anywhere since the appropriate temps for maintenance are also appropriate for incubation.
