Hey there,
I personally feel that glass terraria are one of the worst choices for tree monitors, or all monitors for that point, regardless of temperature and humidity levels are maintained properly or not... There are many other factors which play an important role in health, especially with WC individuals, not accustomed to life in captivity. Some of the issues that I have with glass enclosures:
1) They offer no security. Being as high strung and nervous as most monitors are, especially tree monitors, they need as much security as possible. Having 360 degrees of see through glass does not offer any visual blinds or barriers to give the animal a sense of security. Even if you are standing 20 feet away from the tank, the movement and commotion will still upset the animal, as it has a clear view of whatever's going on in the room. Compare this to an enclosure who only has a glass/see throughh front. I suppose glass would still work in this situation, if it was blacked out, but wouldn't work for the other reason why I do not favor glass.
2) Tree Monitors are climbers- their name says it all, as does their behavior if they are set up properly. It upsets me to see people(I used to be one of these people myself) set up their tree monitors in an enclosure furnished withh only a few logs or branches on the inside. Regardless of how spacious, volume-wise the enclosure is, the animals will not use 95% of it, as they are confined to the floor and the measily few branches in there.
I have found that in my experience with experimenting with what my tree monitors prefer, that they will spend the majority of their time in a vertical position, if given the opportunity to. Most people, when setting up enclosures put branches horizontally or diagonally oriented. While this is fine to include, you are leaving out one important dimension.
Look at trees, and how the trunk of a tree grows-vertically. They are going to be utilizing vertical trunks moreso than horizontal branches in their daily travels, as they move from the upper canopy down to the lower branches, and even the ground. Now that I mention it, it is actually rather rare to come across a diagonal trunk or branch, unless you encounter a tree or branch which has snapped or fallen, and is being propped up on one side by another tree. Branches/limbs typically grow horizontally, and trunks grow vertically. But yet, people always choose to do the diagonal orientation, and omit the vertical dimension. Which leads me to my point.
Tree monitors- all monitors will use vertical climbing areas. I choose to offer as muchh space in my enclosures as possible for them to use. Therefore, i cover the walls with a climbable material. Not only does this triple(at least) the total amount of climbable surface area, it also allows for a greater range of motion, as opposed to the diagonally up or diagonally down, or side to side motion. My monitors can use the walls to avoid one another, reach different tiers/levels within the cage, or to get to their different hiding spots.
So I feel that the cage walls are very valuable real estate and should used to offer as much usable area as possible. Remember, we are drastically confining what their natural territory/range would be by sticking them in a 'box'. Why not try to offer as much as possible, as opposed to the minimum??
Along with covering the walls of the enclosure with climbable material, I also mount tight fitting cork tubes(cut into sections-not a complete tube, more like 1/3 of a tube), so that it forms sort of a hollow tree trunk cavity. On each 'trunk' I have several different crevices and different entrance points. They have many different hide spots that are located at different heights in the cage, offering slightly differing temperatures. There is also several within each enclosure, so that the two animals would not have to share one(having choices). I typically create four of these 'tree trunks' and orient them in each corner of the enclosure. While I suppose that you could still use glass for this, i think you would have a difficult time mounting any usable material to it that would hold up to the abuse the monitors would put it through. With theh cork tiles I use for the walls, i screw them into place, as opposed to siliconing them, as the nails of the monitors eventually wear out the tiles, and they will need to be replaced. By screwing them into place, this creates a much cleaner and easier method of removing the old, and replacing the area with a new tile..
This is just what I have seen in my experience.. I am quite fond of my current setups, as they are relatively inexpensive, functional, and even a bit aesthetically pleasing. I just do not like how 'unflexible' glass or similar materials are when designing a cage that works for tree monitors. I feel that they need every square inch of the enclosure to be usable, and I feel that this really can't be acheived easily with glass.
Just my thoughts on the matter.... I hope this helps, or gives some insight into how I keep my animals. I am in the process of taking some new photos of all my enclosures, as I noticed that I did not have any photos of my own enclosures up on my website. There are many other photos of other people's caging, especially the european keepers, and you will see that most of them use a similar method to mine(i got the idea from a fellow European keeper). Sorry for such a long post, when i get started, i can talk for hours... I hope some of this makes sense to some people... Take care, have a wonderful day!
