People are probably going to think I'm crazy, but I keep a couple of these around my free range setups. Atticus, my Oustalet's love's drinking from them and so does Blix, one of my Melleri. Here's the deal though before people start blasting me, I'm a clean freak. I take them down everyday and wash them. I know that may sound far fetched, but I work from home so I have the luxury of time with my chams. Neither one of the chameleons listed had to warm up to the cantina either, they immediately went for it and loved it.....I was honestly surprised. I will say, if my situation ever changes and I know that I won't have the time to maintain the two fountains, they would have to come down. Bacteria is bad news for chameleons and I wouldn't want to risk it.
