We saw them in Hawaii and recently in Indonesia – the Longnose Butterfly Fish. Vibrant black and yellow colors and a very unique and distinctive snout/mouth. The big black spot on the back is meant to make it look bigger than it is so predators will think twice about approaching.
It might look familiar as one of Nemo’s buddies at the start of the movie is named ‘Tad’ and he is a Longnose Butterflyfish
