I dont know what type of Oscar this guy is specifically, but ive had him since 2 inches. Hes now about 8.5-9 inches. I read on wikipedia "Oscars" in general can get to be 18 inches. I thought they maxed out at 12 or 13ish, but im not sure of my O's species so I cant make a real guess. Any ideas?

Thanks

Oscars can get to around 14 to maybe 15 inches. I've never seen a confirmed 18 inch Oscar, I'd pay money to see a 18 inchers. Yours will probably get to around 12-13 inches

at that size would say he about a year old? the oldest and largest known kept Oscar still alive is in a Austria aquarium, 22 years and 18 inches. after a year or so they really slow down, can expect say a 5 year old well kept Oscar to approach 14" , kept fish tend to be smaller than there wild counter parts. water quality and properly fed diet everything with long term growth.
 
To my knowledge there's only 2 species of Oscar. Ocellatus, crassipinnis. Yours is the common Ocellatus
