As the name suggests, this rock looks like the tail of a fish plunging into the water. Renowned for its good feng shui, the rock is located on the former Hoi Sham Island; a small temple to the dragon goddess Lung Mo once stood at the foot of the rock, accessible only by boat. Land reclamation in the 1960s swallowed up the island, which was incorporated into the new Hoi Sham Park and you can now relax under the trees in full view of the fishtail. Although the temple was demolished in 1964, its statue of Lung Mo was saved and relocated to the historic To Kwa Wan Tin Hau Temple nearby.
