I've kept water dragons before and while wonderful, they take a slight bit more work than a chameleon, in that they foul water VERY quickly, much like green iguanas. If you do decide to get one, build or buy your enclosure for easy cleaning/draining of the water features because you'll be doing it every other day. If I was to buy another, I'd put in a sink drain that emptied right into my sewer, filtration in the water, and a spray nozzle attached to my water lines to clean it out. This will save a lot of cleaning and headaches in the long run trust me. Good luck!
