"I bought this for my chameleons and it's tall, but I was expecting it to be a little bigger. It's a great size for younglings, but looks a little cramped for adults. After a while I gave this to my Indo frogs and they love sitting in their water dish but they were afriad of the running water for a while. The motor isn't too loud, more like a hum. So it really depends on your pet. I didn't have too much luck, but purhaps a different type of herp like a young water dragon or something would enjoy this more."
