Is also known as Opah, the Moonfish is a stunning-looking fish – round, with a thin body like pomfret and a striking blue and pink skin with red fins. 

It can grow up to 100kg, living at depths of 100–400 metres in parts of the oceans and swimming as far north as the UK during Northern Hemisphere summer months. 

Under its striking colourful skin, it has firm, Salmon-like flesh, which is very highly rated. Best filleted and pan fried. 

Not easy to obtain, but do not confuse moonfish with Sunfish (Mola Mola) – which has a stubby, flipper-like tail and dark brown, leathery skin, and should be avoided.
