Flowerhorn not eating

Question
I have a flowerhorn and he has not eaten for a week. I have been feeding him the usual flower horn pellets all the while. Also, he just stays at one corner of the tank and is always slanted to one side as if he wants to lie down. What can I do?

Answer
Hi Kevin,
  Is the temperature in the tank up to normal (around 80oF)?  

Also, have you been doing regular partial water changes, of about 20% each and every week?  That is essential.
