I have a local fish store Oscar I have had for 4 years. I also have a Peru wild Oscar that I have had for 6 months. They live in the same tank with no fighting.They are both tiger Oscars. The local fish has very deep black and vivid orange. The wild Oscar the black are very muted ranging from dark gray to an tainted white. All the fins of the wild are tipped in orange. I like the contrast the two fish offer in the tank. I can see how a wild fish would want the muted colors. As he ages we will see if his color changes.
