tiger oscars

Question
hello,
ThiS is kind of an urgent question. My tiger oscar is very pale with foggy eyes and a weird substance is floating on him it looks like a spider web ive done 35-40percent water changes twice now yielding no results he also will not eat. Please help me!

Answer
He might have ich or a fungus growing on him. Pictures would be preferred but you can identify easily using Google images and typing in "Cotton growth on fish".

Fungus is normally caused by poor water quality or an immediate fluctuation in temperature, PH crash or other.

Would you mind telling me what tank size it is in as this will help me give you give him medication to clear this up.
