There is no strict definition of this classification of reef fish, which I arbitrarily determine, referring to fish that live in the attachment of coral reefs.
Hong Kong butterfly, that is, Hong Kong butterfly fish, it refers to a species of butterfly fish, perhaps a unique species in Hong Kong, here I use this name, because it is easy to remember.

Hong Kong butterfly, also known as black eyebrow butterfly, black tail butterfly, Wei butterfly, raccoon butterfly, lily butterfly. The body is yellow in color with reddish-brown stripes and black and white stripes on the head.
This butterfly fish is also remembered when it was seen at night dives in Dapeng's Bayberry Pit Deer Tsuiya.
