Help! I got two ADFs from the pet store last week. They both were dark, good sized and fast, so I thought they looked pretty healthy. A week later one of the guys developed a fuzzy foot, which I noticed he stopped using. I separated him, and have tested his water religiously, but the fuzzy and discoloration seems to be growing. The tank he was in is 10 gallons, has one Molly in it, a live plant. The water has tested good, not great, but good. The ammonia has been under .5, and I'm trying to get it down to zero. The other frog is fine, active and eating. This guy ate when hand fed last night and is moving around. I hope I can save him...but I'm not sure what's wrong with his foot! Ideas? Suggestions?
