Reddit mentions of Giant Lizards

Niles are one of the largest, most active and energetic lizards in the world. These dimensions are for the smallest enclosure that you could keep it in. Also, it will need a large pool with a full on filtration system, the kind used for swimming pools. It will probably destroy cage furnishings made of foam, even after covered in grout. The enclosure must be built extremely sturdily, because pound for pound, Nile monitors are at least as strong as crocodiles, maybe even stronger and have far better endurance. He will be able to break out of a poorly built enclosure.

When it is an adult you will have to feed it a variety of crustaceans, fish and birds, eggs and only limited amounts of rodents. It needs whole prey food. Can you provide a very large enclosure, with correct lighting, heating, humidity, substrate, pool, with sophisticated controls (expensive thermostat / hydrostat) and still afford to keep it well fed? Can you afford exotic vet visits? Keeping a monitor lizard this large will not be easy and will cost in the ways I've mentioned but also in electricity bills.

I've read your posts and though you know very little about keeping monitors, you seem willing to learn. Here is a list of books that will help you learn about these wonderful but difficult to keep animals:

  Much of the information online and care sheets are made by pet store chains that want to sell as many of these wild caught babies as they possibly can and thusly are full of misinformation.
