This has to be a troll. Its probably one of the banned members or something. Someone with powers should look into the ip address maybe?
I think maybe this is a young person.
He’s been warned about housing oscars in this tank a year ago.

 
I'm just going to ignore all this drama and answer your question. Some predators for a 55 could include

Blockhead/lionhead cichlid
Dragon pufferfish
Leopard Bush fish/leaf fish
A rainbow wolf fish (erythrinus erythrinus)
Golden wonder killifish (will eat shrimp, baby fish and small crickets)
Axolotls (they'll eat worms, shrimp, and small fish)
A pike cichlid that stays in the 6-8 inch range (there's numerous ones like that)
An African butterfly fish
A figure 8 or green spotted pufferfish (brackish)
You could get away with a Jack Dempsey or green terror (ideally females as the males get larger and the males might be slightly too big for your 55)
A salvini cichlid could work as well
A school of exodon (as previously suggested)

Or you could do what I used to do and use it as a growout tank for larger fish, in this case I had a friend with a 4,000 gallon pond and he'd have me get fish to grow out in my 220 so that way when they go into the pond they don't get torn apart, I've grown out temensis (up to 24 inches), arowanas, red tail catfish, shovelnose, etc. Those are fish that would not (or barely) fit in my 220, so it was a lot of fun to have them and watch them go from tiny little 3-4 inch fish to these behemoths that ate crayfish, whole silversides, etc.

Yes, but fish are smart enough to adapt so they grow less. So my oscar was only 10 inches many people say put it in like a 120 gallon but you have to realize that's stupid
No, what happened is your fish got stunted which probably explains why it died. Some oscars only get 10 inches, but they usually get 14 or so.

So thats awesome. This Oscar lived about a year........what happened to the other one? No reply to the other thread. Why did the Oscar die? Learned 0. Needs no fish suggestions, especially the type that will make a mess when eating and foul the water easier. Maybe a school of hardy tetras or something to learn on before getting larger more fragile/demanding fish. And honestly tetras are pretty roudy come feeding time they are deffinately aggressive fish.
I know the truth hurts....flame away..

I had my oscar in a 55, but once he hit 8 inches i realized he needed a larger tank so I moved him into a 90 and he grew to 14 inches and lived a total of 9 years, if you can't keep an oscar more than 5 years then you shouldn't be keeping them

I think a 75 gallon would be the minimum for keeping a oscar through my research.
