Hi, I'm from Singapore and firstly I must congratulate on what a great forum you have here.
I'm in the process of convert a standard 60cmx30cmx45cm aquarium tank into a lateral vivarium which will eventually house 1 or 2 tree frogs, below are the drawings, the brown lines indicates the original tank and the arcylic/glass in black
Right now the bottom pc is glass, center(door) is arcylic whilst top pc either
1. glass-which will not have any ventilation holes or
2. arcylic- which would be easier to add in ventilation holes.
I still haven't make up my mind on this...
Another idea is to install a PC fan to the top pc but haven't work out how to attach that to the arcylic yet..

:
The hinges on the door are arcylic and the black bit on the top of the door will have a lock.
Comments & ideas most welcome.

Cheers,
Ken
