Those are some very nice looking little Os, congrats
I have a trio of oscars in my 150 that are about 75%wild, one of their parents was wild the other was half wild half domestic. They looked exactly like yours when I got them. They are all around 9-10" now...I assume I have 3 females because there has been no signs of breeding behavior or any aggression whatsoever they school like a pack of tetras tho. Ill try to get some pics of them sometime this week, if youd like. But really whats the point of getting any fish that is commonly bred captively wild caught? Or whats the point getting your fish from a breeder instead of a LFS? To me its the quality of the fish you are buying...we all know there are alot of crap genetics floating around expecially in commonly bred fish.
