The vivarium I'm using is completely custom tailored to this build. It's starting off as a 20g tall fishtank with rims removed. It will then be flipped sideways onto its small side leaving the open side on the right of the viewing side. (i suck at explaining things)
I will then use three evenly measured pieces of glass to seal the opening. One fixed at the top and one fixed at the bottom, then the middle one will be removable with magents holding it in place. The ants will be completely sealed off from the other bugs and plants (and i mean completely, or i won't do it), and only have certain sections that they will be able to access.
Here's a small mock-up of what i want to do. The highlighted sections are the ant sections. The center is a "Trench" area, so use some imagination please.
The front nesting area will be removable, as well as the dome around the ant hill. I'm still in debate if i want to be able to slide the nesting area out sideways, or have the front section of glass covering the nesting box removable with thumb screws. I want this section to be accessed entirly different then the actual opening to the vivarium, reducing the chance of ants making in to the display tank.
All of these will be connected with a short series of tubes hidden under the substrate.
