This very unusual marine angelfish is being sold by The Abyss in Stockport, Cheshire.
Described by Anne-Marie Powderly of The Abyss as "a little super-rare beauty", it's an abberant Centropyge called a Fire fin coral beauty.
The rarity is reflected in the price tag — this fish is on sale at the store for £1,299.
"There's very little known regarding these abberant Coral beauties and what makes them so weird and wonderful," says Anne-Marie. "But he certainly is by true definition 'one of a kind' ".
