Sorry about that, I had completely forgotten that I had started the thread
Anyway, I did get the visionarium. Assembly was very easy. I didn't even need the directions. It is not very practical for very small lizards. I gave it to one of my employees so I can't say exactly how big the gaps are, nut small crickets would get through the vents and the gap between the sliding doors. It might work OK for larger geckos that take larger crickets though. I spoke with a rep and they said they were working on the door thing. It might be possible to modify it with some aluminum window screen but then you might as well build your own cages. Also, there is no litter dam to speak of just about a 3/4" depression so anyone using a substrate would likely have problems with fallout when the doors were opened. I was informed they were working onthat also. As far a the heat and lights, there is not room for both types of fixtures. If you need UVB and overhead heat you are SOL. If you do not need uvb and can get by with say 50 Watts of heat you could use a 24" Incandescent fixture with two max rated 25 watt bulbs. I don't know the dimensions of the fixture such as the reptile Bi lights from esu but I don't think they would fit. They seem to be designed with the All glass aqaurium type fixture in mind. Even if the Bi lights would fit I would be worried that any higher wattage bulb might melt the plastic bottom of the upper cage.
I decided to give it a pass. It might be nice for a snake with an UT heater, about the only problem I could see then would be the fallout problem. It's a nice idea but it needs a bit of tweaking. The unit looks good and I could see how a stack of them, would look very nice but there are too many downsides to be practical in my opinion. If they solve the litter dam problem and come out with te 40 breeder size I may consider them for my personal collection of small colubrids. Then again I might just look for one MFG that offers everything just to keep things uniform.
