unfortunately the one i was concerned about died today.... im sure that it was redleg....

i posted another problem:

I had a frog that was showing symptoms of redleg. I took him out of the main tank to a hospital tank so he could hopefully get better. He was looking alright so i moved him back to the main tank with another ADF. BUT when I got home today i found the ADF that i was concerned about dead with alot of missing skin. I cleaned the tank and replaced the water but how can i ensure my living frog doesnt get sick from the dead one??
