Killers of the deep

Predatory Fish

Discover some of our species...

Giant Trevally

Giant Trevally

The Giant trevally is a large openwater predatory fish found throughout the Pacific and Indian Oceans. A powerful apex predator, the Giant trevally hunts both alone and in large schools. Juveniles favour lower salinity waters and can even be found in rivers and coastal lakes. Ours - Trev - can be found in the Great Barrier Reef exhibit.


Golden Trevally

Golden Trevally

The Golden trevally can be found in the tropical and sub-tropical waters of the Indo-Pacific region and can be easily distinguished from similar species by its uniquely golden yellow pigments and black bands. Juveniles have been observed swimming in schools following large ‘pilot’ fish such as groupers and sharks. They can reach sizes of up to 1.2 metres in length and prey on molluscs, small fish and crustaceans.


QLD Groper

Queensland Groper

Our 1.6 metre Queensland groper - Beau - arrived here in Spring 2013 in no less than 2.5 thousand litres of water, complete with a forklift to assist the move! Growing up to 3 metres in length and comparable in size to some of the largest sharks and rays on display at our aquarium, the Queensland groper is also commonly referred to as the Queensland grouper, Giant grouper and Brown Spotted cod. This mighty fish has a powerful sucking mouth to pull in prey, which includes fish, octopus, crustaceans and even juvenile turtles!


Black Cod

Black Cod

The Black cod, or Saddletail grouper, native to the south-east coast of Australia and New Zealand has been recorded to reach sizes of up to 1.5 metres in length. They can usually be found inhabiting rocky shores or coastal reefs and feed mainly on crustaceans and fish. Due to their near-threatened status, the Black cod has been protected in NSW waters since 1984.


Diamond Trevally

Diamond Trevally

The Diamond trevally bears an uncanny resemblance to the diamond shape, and can be found inhabiting the coastal waters, estuaries and seagrass beds of the Indo-West and Pacific Oceans. The can grow up to 1.5 metres in length and their diet is made up of mainly crustaceans and occasionally small fish. Juveniles have ribbon-like extensions on their fins, tricking predators into thinking they are jellyfish!
