My Oscar is sick can anyone help?

Question

my oscar fish is breathing heavily and I notice a white bubble in its mouth when it breaths. Whats wrong I have tried everything tested everything and it's all reading good. I have an air bubble stone in the tank. Its been doing this for 3 days now

Answer 1

I'm guessing it either has ich or mouth fungus, but there are other possibilities too.  try taking the stone out and adding some aquarium salt to the tank to make the fish feel more compfortable, and in the mean time look up the disease and find a cure.  good luck!

Answer 2

Try feeding him soft foods until he gets better. He might have cut his mouth and got an infection. Hopefully he recovers.
