My favorite fish is the discus fish. First discovered by Dr. Johann Jacob Heckel. It is a freshwater fish mainly found in black water rivers on the amazon in Brazil. It is named due to its disc shaped body. It lives in tree roots of the mangroves. Their disc shaped bodies help them glide easily in between these narrow tree roots. This helps shelter them and protect them from predators. They have the most unique patterns of any freshwater fish.
