Lund said:It seems like every time I post I learn something new. It's great!. The research I have done said that oscars reach 12" or so. 15" is quite a bit bigger thanks for the heads up. How can you tell that you are getting a male or female? And are oscars compatible with black ghost knife, or clown knifes in a 200 gallon tank? Even if they are introduced at the same size. Or are they just too aggressive
