There is so much conflicting information on this species 
I have one small heat pad on the bottom of the terrarium, I'm not sure if I need a heat lamp or another heat pad on the side of the aquarium. It seems every care sheet recommends something different. The place I bought the frog from said they did not need a heater, some sites claim as long as the aquarium temp is above 68 degrees you do not need additional heating. Other sites say it needs to be 85 degrees. Anyone know which way I should go with this?
