ADF weird death

[Phoebastria]

One of my ADF died a couple of days ago in pretty weird conditions. She was doing well moving around in the tank. One morning I woke up and she was at the top of the water swimming frenetically around. Although she could swim down to the bottom she could not stay down as they do usually. She was really buoyant. She also had a white patch on her back that appeared overnight. I was worried that it was a fungus and I would have treated the tank once back home from work but she was dead when I came back .
I took the opportunity to look more closely at the white patch to see if I still had to treat the water since I have another ADF. I turned up to be nothing like any fungus I have seen. It looks more like a wound or the skin that turned white. I join pictures here. If any have an idea so I can prevent it from happening to the other one. One of my theory is that you can see what looks like two little holes on the top of the patch on the close up picture and it kinda fit the shape of the teeth of my zebra snails. Could it be a snail trying to get a snack off the ADF or accidently doing so? I would have though that frogs would be too fast and would have moved as soon as she felt the snail on her but I am not sure.
Any ideas?

The snail was most likely feeding on the dwarf frog postmortem which is what snails do.

Nope. The patch was there before it died

http://www.frogforum.net/aquatic-cla...nnot-dive.html a similar question was asked a while back, not a definite answer but somewhere to start. Help With Frog Please! in African Dwarf Frogs Forum <- I also read a bit on this site with someone who was having similar issues and various aspects of the tank, feeding, ect were explored a bit. The wound def look as though the snail got at him so maybe while the poor little one was weak and not moving very much or after he died. I have had experience with fungus and it was very obvious. Injury from something else in the tank could have caused the white spot and maybe she did some damage? Just a thought, I am no expert but hopefully these links give you some idea of what could have happened, so sorry for your loss

I'm sorry. That is so sad. I hope this gets figured out.

I agree with Michael, it is an injury caused by a bite. I would remove the snails.
