So the enclosure is basically finished. All I need to do now is splice some wires, put the lights in, and seal it up. I need to find a way to close the gap between the plexi. Im thinking the best option is to screw a couple lengths of wood across the plexi. Basically a third track placed at the middle-heigt of the cage. I am sooo stoked for this to be fully finished. I'm debating putting marine silicone(I use it in a few enclosures, no emmissions) anywhere other than the ventilation/plexi that air gets in our out.

Sadly I am faced with a dilemma at this point. Once I complete this I will want to use it, but have no idea who I should put in here.
Right now it is between my two adult male pugets and my two adult female ordies. I have 3 adult vagrans right now aswell (1.1.1) and I would like to give them something special, but we all know how vagrans are. I don't want to risk stress, fights, breeding etc. The BIG female might be able to swallow one of the others, but she would be hard pressed, as they are only like 8 inches smaller than her. The other two are around the same size, and if I had to guess at gender I'd say both male, but I do believe one could be a female. At first I wanted to keep a group of 4 or so male ordies in there, but that entails more new additions and more quarantines that I dont have space for. If you were in my situation, who would you choose to give paradise to?
