11---describe the enclosure lighting ( very specifically)
The tank has been moved near to the window. There is one UV light and a spot light too. Which direction does the window face? If it's south or west you could be getting temperature spikes that are too uncomfortable or unsafe for the frogs. Same with humidity drops (though your levels are sounding spot on right now). Your temps don't sound too bad really, though the lower reading might be a tad too cool.
15---enclosure set up:
-----if recent - describe how the enclosure was cleaned
Used hot water to clean the walls of the tank, took out the fake plants and waterfall and dishes and rocks get soaked in hot water in the sink. Did you use a dechlorinator product when rinsing?
