What do you think? The fish in this picture certainly looks rather like a Koi...but read on!

When is a Koi not a Koi? When it’s a Harlequin wrasse (Bodianus eclancheri)!

Native to the South-East Pacific, this reef-associated marine fish is also found in the cooler waters off the Galapagos Islands where, like many of the Island’s other fauna, unique species variations produce these bi-colour and tri-colour versions, when in many other parts of the world this fish will be a dull grey.

Did the pattern make Koi fans look twice? We certainly did!
