One colourful and characteristic resident of the Great Barrier Reef tank is Cooper the humphead wrasse (Cheilinus undulatus). Named because this species can grow to two metres in length (the size of a Mini Cooper) as one of the largest reef fishes. As well as around 70 other species dwelling in the Great Barrier Reef tank, Cooper lives with another humphead wrasse called Mini! She’s tiny in comparison, so you’ll need a keen eye to find her! As characteristic of wrasse, they begin life as females, until the most dominant female becomes male as they get older.
In the wild, humphead wrasse are mainly found on coral reefs in the Indo-Pacific region. Unfortunately, humphead wrasse like Cooper are under threat in the wild from fishing pressure and high demand for their meat.
