Nocturnal Frogs?

[ShannonPerson]

I have a 5.0 UVB light that I use during the day (about a 12-hr cycle), and they’re next to a window that I always keep closed and the curtains drawn so no natural light comes in. I have to say, though, in the time that's passed, they’ve gradually become more active during the day, so maybe it was just the time of year.
