This is one impressive fish and quite possibly the fastest fish on the flats. Get one on the boat and you won't want to stop looking at it, they are truly a novelty capture - but it needs to be back in the water to keep on being amazing.

It takes its name from its shape but the metallic greenish to yellowish to gold and silvery hues are something to behold. This is a tough combatant on a fly rod - the deep body and typical trevally metabolism and attitude give it power and stamina.

Once hooked these fish go like stink at first - they always have an escape route in mind - get through that with leader intact and they'll settle into a dogged, sideways battle of arcing and plugging to avoid being brought to the boat.

Most fish encountered are in the 3 - 6kg range but it reaches a maximum length of 1.5 m (5 feet) and a weight of 12.7 kg (28 lb.).

Occurs from south-western WA, up throughout the tropics across the Northern Territory, far North Queensland and around to the central coast of New South Wales.
