Stunningly vibrant

Tropical Reef Fish

Discover some of our species...

Clown Anemonefish

Clown Anemonefish

On any day of the week here, you'll see children enthusiastically prodding their fingers against the glass shouting 'I found Nemo!' The Clown Anemonefish is highly adapted to its environment, striking up one of nature's most unique partnerships as a defence mechanism. Juveniles develop an immunity to certain types of sea anemone, within the tentacles of which they hatch. However, it's a short-lived mode of protection, as this immunity needs to be regularly maintained, seemingly wearing off if the fish leaves its host anemone for as little as an hour.


Blue Tang

Blue Tang

The familiar and friendly Regal Blue tang is renowned for its distinctive royal blue body and tail. They are also commonly known as Palette surgeonfish and the Hippo tang. Regal Blue tangs can grow up to 20-30 centimetres in length and are typically found amongst coral reefs of the Indo-Pacific Oceans, East Africa, Japan, Samoa, New Caledonia and Australia. Juveniles mostly feed on plankton while the diets of the adult tangs are omnivorous, feeding on plankton and algae.


Napoleon Wrasse

Napoleon Wrasse

Our beautiful wrasse (named Napoleon, of course) lives in the Dugong Island oceanarium. This stunning fish is a protogynous hermaphrodite, meaning that they can change sex, but only from female to male. The reasons behind this are not fully understood, but it has been observed to occur when males are in short supply, and so a female - often aged 8 to 10 years - will turn into a male to fill the void. We've witnessed this remarkable transformation first-hand, as our very own Napoleon (previously named Natalie) transformed from a light turquoise to a deep, vibrant blue.


Clown Triggerfish

Clown Triggerfish

The Clown triggerfish is a species of triggerfish found in the coral reefs of the Indo-Pacific region. The patterned fish with its characteristic upturned mouth can be seen exposing its two long teeth. They feed on a carnivorous diet made up of squid, krill, small fish and crustaceans. Triggerfish are very territorial, often chasing intruders out of their patch. Our Clown triggerfish can be seen swimming, steering with their dorsal and anal fins, making their movement quite unique.


Big Nose Unicornfish

Big Nose Unicornfish

The Big Nose unicornfish (Naso vlamingii) is a species of unicornfish from the surgeonfish family that is commonly found amongst coral and rocky reefs. It can grow up to 60 centimetres in length and has a predominantly herbivorous diet, feeding on algae. This species can be found in the tropical regions of the Indian and Pacific Oceans, from East Africa to the Galapagos Islands, southern Japan, through Micronesia and down south at the Great Barrier Reef.

Harlequin Tuskfish

The Harlequin tuskfish is a solitary and monogamous species from the wrasse family found in regions the Western Pacific Ocean. This blue, green and orange coloured species can grow up to 30 centimetres in length and its diet consists of crustaceans, molluscs and other invertebrates.
