Mine will look bloated after they soak too long in the water dish.... and I mean bloated. My littlest one almost looked like a pacman after soaking one night.

Basicly, I keep a red night ling on with a place for them to perch just below it. It seems they go there to shed or places close to it.
Two of the frogs actually sleep under it every day too.

When I mist the tank I often spray them down a little too.
Feeding here is the same as your doing.
