Lighting in Dart Frog Terrarium

[jarteta97]

Since LEDs tend to not be very warm, many keepers will use heat mats (sometimes more than one on a tank) in order to get the tank up to the proper temperature. 15/16 degrees celsius is at the very extreme low of pdf temperatures. At night time, the temp generally shouldn't drop below 18 degrees. Once the weather heats up, you can always remove the heat mat. Also, it's usually best to play the mat on the side of the tank.
I don't think the waterfall will necessarily cause the frog to hide, but it will likely end up crashing. If the frog is recently acquired, then the frog is likely still just antsy around movement. My pair of D. auratus used to flee every time I entered the room, but now they practically jump into my hand when I open the tank.
