So today I say that one of my Yellow Terribilis had a small gray coloration above its nose. It looks like a skin lesion of some sort. I have never had a frog get a lesion before and so I don't know exactly what I should do. I have read a few threads but wanted to get some new advice for my particular case. First, I had to tear down their tank because ants had gotten into the soil and would have soon taken over. So maybe the frog was bitten by the ants. Just one thought. The other is that maybe it is a baterial/ fungal infection of some sort. I also thought that maybe it just rubbed it against something a little too much. This frog never jumps at the top of the tank so this could not be a cause. What kind of treatment does it seem like this frog needs? Any info would be greatly appreciated. Thanks.
