I'm not exactly sure where I would be asking this but I had an African dwarf frog die yesterday and he was my most active one of 3. Today when I went to feed all my tanks my 2nd one is belly up and floating around the tank whether face up or belly actually touching the top of the water. It is still alive but I have no idea what's happening. All of my levels are fine that I know of since I tested 2 days ago and when I sent pictures to my sister (originally her tanks) she said that there wasn't anything on its body that she could see to cause it to die and to ask about it here (if that makes sense). Also I have no idea where my 3rd frog went. I'm really new to managing tanks so any help would be greatly appreciated!
