The 6000 gallon per hour waterfall in my "rainforest under glass" is the life blood of my "vivarium". The splash and spray provide moisture to the animals and plants planted near the falls. And it helps keep the humidity near 100% at all times inside the "rainforest". All plants are misted daily by an auto misting system. I keep a large number and variety of tree frogs and green anoles and am looking for new animals to add. NO SNAKES or Iguanas. My wife hates snakes and iguanas eat my orchids and I've got hundreds of orchids and extremely rare plants in this atrium in the NW corner of Arkansas (note the orchids in bloom at the left on the waterfall). If you have suggestions for animals or are a breeder/seller of suitable animals that are compatible please let me know. I frequently trade plants or plants for animals.
