terrarium setup for frogs with a waterfall
Basically I was hoping somebody had some ideas for a terrarium setup with a waterfall. I originally though about getting some piece of glass cut and siliconing them in to create separate land and water parts, which I still may do, but I am looking for ideas on creating a waterfall. I looking at making this at least a 20 gallon aquarium, long profile one, maybe 40 gallon breeder tank if I get some really cool ideas. anyways, having problems trying to figure out what I am going to do for a waterfall. What kind of material could I use to build at waterfall that wouldnt be toxic to frogs and fish? Could I shape something out of clay or some sort of plaster? Any ideas on an terrarium setup would be appreciated.
