i need some help with my 51/2 inch tiger oscar fish?

[DavidW]

I have a 51/2 inch oscar fish people say that you need to feed him 2 to 3 times a day because he is growing but today i have already feed him 3 times today once at 9 before i went to my friends house then at 4 and then at seven just know but my oscar is going back and forth really fast and then when i go near the tank he goes up to the glass and and opens his month what should i do feed him or not

No. Fisg like oscar will eat until they literally explode he should only be fed once or twice a day. Extra food turns into ammonia and more waste also turns into ammonia which is not to good for fish.
