My friend at the Zoo herp department is going to help me set up terrarium with tropical habitat and filter/pump system. I have access to different kind of mosses and water will be trickling down rocks and into a basin. I volunteer in this department one day a week and study how the different environments are designed. My redfoot tortoises have done very well for 5 years with monitoring the right amount of sun, heat, humidity and diet in hot summers and cold winters. I don't plan on making a decision until I understand fully what is best for the frog I choose. I look forward to your input.
