I agree with Gasha.... Good luck. Like Humans all fish have personalities. generally speaking it won't work. But you never know! I have had 2 big Oscars and 2 big Pacu in a 20 gal and they got along just fine.....I have sen (on you tube) a flowerhorn bully and harras THREE piranhas...My flowerhorn killed his tank mate the same day i got him and bullied an Oscar 3 times his size

dude i wasn't gonna bring it up but lol... that video is mental!!! towards the end the over sized tetra, i mean piranha tried to have a jab at the FH and got housed!!
Yeah, definitely upgrade your tank. A fourty gallon wouldn't hold an Oscar very long. For a single Oscar you would want a tank of a standard 55 gallon. With tank mates you'll want a larger tank.
i'm anti oscar... i won't get into it too much but they are the rodents of the cichlid world... anyways, minimum 55 gallon for oscar?? 75 gallon with decor...this comes up alot on this site i notice... do you guys like to keep your fish in bare tanks??? you should have a cave, some drift wood, and at least fake plants... cichlids love that stuff....
now even though i don't like oscars it doesn't mean i don't think they shouldn't have a nice, clean home...
