I have never attempted to breed any monitor species so no data there.
Which zoo's and meuseums did you do rockwork at? perhaps I have seen your work?
I did some at Cleveland for small modular displays in their education department. That was nearly 20 years ago. Later I did a bunch for a small zoo in Grand Island, Nebraska. I guess a couple of books about zoos mentioned the reptile house I built and gave it nice comments. It is now closed and torn down - typical economics of small zoos.
I helped out a bit with some small displays at interpretive centers and museums in SE Nebraska. Nothing major.
When Omaha built their huge rainforsest I got to go out and work with the Larsen crew and learned a TON, although I doubt any of my work is actually on display there. Maybe a small section here or there that they neglected to cover up
I did get to help make some faux vines with cable and some sort of catalyzed rubber mix. I imagine those were used.
I generally agree with you about faux rock-work but may differ in some regards. At the zoo I tried to create the most realistic textures I could. I made rubber molds of actual rock surfaces and then pounded them into curing concrete to create texture.
For the private terrarium use I have a different attitude. I like to use the rockwork to provide usable structure for the animal but I don't think the texture is all that important, especially in a heavily planted cage. I think something just to provide a juxtaposition to the otherwise geometric and smooth nature to cages is all that is necessary - albeit with the emphasis on providing usable structure for the animals in question.
Don't get me wrong, I would go as realistic as possible if I had the time or the skill, but I think that it's easy to get so wrapped up in that and end up with a less attractive project unless you really do a good job. Sometimes rockwork that is meant to look real looks more fake than rockwork that is just meant to break up the geometric shape of the cage. Does that make sense?
At any rate, I'd like to try some for my displays but can't decide on the technique. Fiberglass and epoxy are out, however. I hated working with the stuff.
