Meet the Redtail Shark (scientific name: Epalzeorhynchos bicolor) — a freshwater fish that truly stands out. Its body is deep black, and it has a bright red or orange tail fin that looks like a flame flickering in water. Aquarists love it because of its striking contrast of colors and its energetic bottom-swimming style. Despite being called a “shark”, it’s actually a type of carp (family Cyprinidae).
