Hinalea'akilolo--Yellowtailed Coris

The wrasses are a family, Labridae, of marine fish, many of which are brightly colored. They are typically small fish, with most less than 20 centimetres (7.9 in) long, although the largest, the Humphead wrasse, can measure up to 2.5 metres (8.2 ft). They are efficient carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing.

The word "wrasse" comes via Cornish from the Welsh word gwrach meaning an old woman or hag.

Wrasses inhabit the Atlantic, Indian, and Pacific Oceans, usually in shallow water habitats such as coral reefs and rocky shores where they live close to the substrate.

The juvenile looks like nemo. There is a blog about him.
