The wrasse family of fishes are usually brightly colored and are very diverse. Their colors are often accompanied with bright patterns which can vary dramatically with gender and age. They are typically born female, and turn male in adulthood as needed. They are typically smaller fish feeding often on small invertebrates and small amounts of algae.
The shortnose wrasse is endemic to Hawai‘i. The adult phase is easily mistaken for the Potters angelfish.
