Okay, so I have a tiger oscar that I picked out at about 1.5" long. It is now pushing 3.5". I love tiger oscars and the personality (of pretty much all oscars), but I do not like the olive green color that a lot of Tiger oscars seem to have. I want it to be pretty much black orange except for the white edges of his fins. I painted the back of my aquarium black and put in black tahitian moon sand in an attempt to darken him up. It worked! He has almost none of that olive green color. My concerns are that his orange isn't very prevalent. Could it be that he is still rather small and it hasn't developed fully yet? or is the black aquarium inhibiting his orange development? I feed a variety of quality color enhancing pellets and keep clean water. Currently he only has a the orange "eye on his tail" (I can't remember the technical term for said mark), and some of his striping is filling in toward his tail but the front 3/4 of his body is pretty much all black. Could it just be genetics or could I do something to make the orange stronger?
