All discus are basically the same. I have mixed wild discus with domestic. You may have even gotten a few "wild cross" fish from Kenny in the 17 that you purchased from him. You might ask what food, water temperature, and water ph the seller has kept the fish in. Also, age fo the fish. One thing that causes me pause with regard to fish imported direct from the wild is that the age of the fish us an unknown. Is the fish a direct import or a domestic F1 or more?
