oscars very inactive

Question
i have 2 4-5 inch Oscars in a 70 gallon tank the ammonia,pH,nitrates,nitrites are all good the temp is about 78 F and i have great aeration and filtration neither of them seem to eat anything I've tried cichlid pellets,worms,dried shrimp,and tropical flakes i do regular water changes and there is no visible signs of disease like ich,velvet,fungus ect.. they are also very inactive they mostly stay at the bottom of the tank i have run out of ideas

Answer
Hi Adam,
  How long have you had these fish?  If it is less than a month, I wouldn't be worried at all.  Oscars take a long time to get used to a new home.   

  When you say "regular water changes", how often is "regular"?  You should be changing 25% of their water once a week, every week to keep them happy and healthy.
