The Great Barrier Reef is home to a minimum of 1500 and perhaps up to 2000 species of fish. They cover the spectrum in a vivid display of ever changing color and diverse characteristics. To satisfactorily explain their tremendous range would require an encyclopedia.
Their vibrant colors are the most impressive feature of the Reef's fish, an endless array of striking blues, yellows, purples greens and pinks. The colors serve many functions, camouflage, warnings, mood changes, recognition of species or of sex, and to cause confusion of predators. Most of the brilliant colors are found in the shallow waters where the sun's rays penetrate and illuminate the kaleidoscope created by the abundance of Reef fishes dancing and foraging among the colorful coral gardens.
Some of the more plentiful fish you will see are the Parrotfish, Angelfish, Butterflyfish, a variety of Wrasse and Damselfish (which include the ever popular Clown or Anemone Fish we know as Nemo). At greater depths you will find the elusive loner Coral Trout, and schools of Barracuda, Trevally and Mackerel. Some fish are predators, others scavengers and there are herbivores, carnivores, algae feeders and plankton filter feeders.
One of the most interesting features of many Reef fish is their ability to change their sex during a single lifetime. Some change from female to male as is true of Parrotfish, the impressive Maori Wrasse, Angelfish and some Damselfish. Others change from male to female like the spectacular Scorpion (or Lionfish), Snappers and our own Nemo (Clownfish). Many of these fish mate for life, the Moorish Idol, Butterflyfish and Angelfish. You will always see them in pairs while you are quietly observing. Many are quite territorial and never stray far from home, others are pelagic in nature and forage over vast areas.
The unforgettable display of fishlife they provide is available for all to enjoy from the dry comfort of a glass bottom boat tour, an interactive snorkel experience or the compelling opportunity to dive into their world.
