I don't fully agree with the necessity for water bowls for this particular species, but they have water bowls now and I'm not going to argue. But I can assure you that my frogs were not dehydrated before...
I dust their roaches with calcium and vitamin powder in the winter every few weeks, in the summer they get a wide variety of wild caught insects.
And I think the little guy is getting better. His colors are lighter and he's eating more. Hopefully he'll stop pacing.
