Get rid of the light!!!!! They are nocturnal and the albinos are sensitive to the lights, they can burn from them.
I use peanut butter jar lids for soaking dishes with just enough water to hit the bottom lip of the frog so it doesn't drown.
What are you feeding it & how often? Are you making sure to use ONLY de-chlorinated water in it's enclosure & soaking dish??
you can use saran wrap on the screen lid to cover 3/4 of the lid to keep the moisture in and help with the humidity levels.
