Kurt, The frogs started with red thighs and walked around slighty raised as im guesing it hurt. I noticed they spent more time in the water, I thought it might have been soothing, how ever some frogs just sat out in the open and didn't move around as much and their skin was kind of dull. The breathing was shallow and they looked abit hunched towards the end. When they died their tummys and thighs were very red and they were not as fat as they usually were. Their little hands were clenched and red too. It took weeks for them to die and it was horrible to see as you could tell they were in pain.
