I visited all four pyramids. The feature is still set up for Chinese New Year - the year of the Ram. That is where the water fountain was set up. From a bit of research it is a steel cup cascading water fountain. There was a pink/purple peace lily. In the tropical pyramid the waterfall ends in a pond where I found 3 large Koi fish. There were many orchids, the one I chose is the boat orchid (cymbidium).
