Hi everyone, i have a oscar who I salvaged from a bad tank. His fins were chopped up and his eyes are cloudy. I dont see him actively eat food( I know for a fact he did in the old tank). I came home today and the cloudiness is worse while he was on the bottom just resting. This is unusual of him. any advice on what it is and how to treat it is greatly appreciated. Need an answer ASAP, I reallly like this guy and dont want it getting much worse.
