Our new Copper-banded butterflyfish at the Aquarium is beautiful. I could not resist sharing a short video. Also called Beaked coralfish, these Indo Pacific reef fish have elongated snouts with small mouths so they can feed on invertebrates in small crevices. As well as the lovely deep yellow bands these fish have a large false eyespot on each side. These eye-like markings are thought to deter potential predators.
