Waterfalls are one of the most overrated decor items for the reptile world. I had one for awhile with my water dragon. They look cool and help improve humidity levels but are jsut not worth the daily aggrevation. Also if you have hard water that takes a toll on the pump real fast. As others have said I would not reccomend one for a snake as they like to cram themselves into any spot they "think" they might be able to fit in.
