Sure, Oscars will gladly take seafood. Seafood is very good for humans, so it certainly won't do your Oscars any harm.I sometimes give mine cockles and mussels from the fish store, of course minus the salt and vinegar.
I would stay clear of goldfish if I was you, you never know what sort of diseases they are carrying.
in addition to this, i used to tossed squid
tentacles in my O's tank whenever i got one... they love it. anything food that you like could be thrown in, just make sure the are no other additives yet in the items especially the vinegar that could damage the intestine.
