oscar sideways

Question
my oscar is floating sideways. I have tested water & it has no ammonia and the ph is good. what can i do to help him. He has been sideways for 2 days now.
he is in a 30 gallon tank alone. he is about 10 inches long. the filter is a wisper 30  

Answer
Hi Stephanie,
 That is not good at all.  A 30 gallon tank is not big enough for an adult oscar.  Have you been doing lots of regular partial water changes?  Even though your tests say the water is fine, you still need to change 20% of the water once a week, every week.  I suggest you do that immediately and in fact, I would do a 20% water change once a day for the next several days and hopefully that will help.
