I have to disagree with aquariums being horrible for monitors. If they are setup properly they work just as well as everything else. I know a few people that use aquariums as "raise up" enclosures for high end Aussie dwarf monitors with great success. I use a glass enclosure to house my baby blackheaded monitors.

It is all about proper setup. A tank with a screen top and high wattage light is only good for making reptile jerky, but a tank with a plexiglass top and low wattage light can be a great enclosure.

To me the issue with aquariums for monitors is size. Their sizes are great for babies and some dwarfs but there are not many tanks that can handle the amount of substrate and space needed for a monitor over 2 feet long.

If you need any help with setting up a temporary glass enclosure properly just let me know.
