Size?

How large can an Oscar grow? I've tried to find the answe online, but all aquarium pages have their own suggestions. Some say 12 inches, some say 15 inches, some even 20 inches. How big was the biggest Oscar you've seen?

I have seen an oscar that was way over 20". It was the only fish in a 125 gallon tank and it can barely turn around. It tail hit the back and his head hits the front of the tank. It eats dog food.

I hear the biggest an Oscar can grow is 18", but if your certian it was 20", well then Ill have to take your side... GO OSCARS!
