It is hard to believe these 2 were only about an incha nd a half long when I got them almost a year ago!! They are getting huge! These are the 2 that buddied up and beat the tar out of everything else in the tank including the other 2 oscars I had to start with. The other 2 have been rehomed and now my big babies have a tank to themselves! I still don't know if they are a male/female pair though...anyone know??
