I am so sad my frog was eating just fine and swimming around everywhere with lits of movement. He looked healthy and had no signs of any diseases or tumors. I left around 2 in the day and came back the next day at 3. He was dead with no signs of anything wrong. I have absolutely no clue what happened! I inspected over his body and it seemed totally normal.
Does anyone have ANY idea of what happened to him?!

I tried attaching pictures of his body but my phone won't let me
