I got my oscar fish, Mace, at Petco in October. They told us he was the last Lemon Oscar, but I don't think he is a lemon?? I can't seem to find much on baby gray oscar fish and what they are... and I don't think he could be a discolored tiger oscar because I give him a healthy variety of foods and even tried color enhancing foods but nothing happened? Anyone know? He is light gray with orange spots, black tipped fins, and white stripes. He does change his coloration by making the white stripes brighter whenever he feels like it, but that's it.
