So, I bought an oscar about a month ago from walmart (yeah, I know, big mistake....usually), but it is turning out great. After ridding itself of ich after a few stressless days in a much bigger tank with no tankmates, it started to develop a great personality. He(I'm guessing its a male, I have no idea) comes to the top every time I am near it, and will eat directly from my hand. I believe he may be a longfin, but I am not sure. When I got him he was a brownish greyish color with beautiful spots leading from the front of his body to his tail, with an eyespot on his tail. Now that he has grown another half inch in my tank, he is starting to get his tiger stripes on the rear of his body. Do the stripes come in as the fish mature, or do most tiger oscars have their stripes when they are young? I got him at 3.5" and he is now 4".
