High Fin Butterfly (Australia) Marine Invertebrates The Lookdown may grow upThe strikingly unique High Fin, or Tawneygirdled butterfly, has fiery stripes running over its body and fins in a blazing orange and yellow, like glowing embers. One stripe runs through its eye, another V shaped stripe over its front half, one through its rear fins and a small black blotch at the base of its tail. It grows up to 7 inches and needs an aquarium of at least 125 gallons. It is found from Australia to Thailand but is a very rare import.
