View the slideshow to see identification of Fiji’s Butterflyfish species.
Created for divers, snorkelers, aquarists and all marine enthusiasts, this “V.I.D” (Video ID) Guide covers the incredible marine biodiversity of this fantastic corner of the South Pacific.
It’s an comprehensive identification guide to 1272 animal and plant species — except that instead of being a book full of pictures, it’s a video with gorgeous real-life footage of each species, and each of the 1739 video clips is labeled with the common and scientific names of each species.
Marine Life of Fiji and Tonga: A Video Identification Guide
Some Butterflyfish only eat the tentacles of the actual coral animals, and so are totally dependant on good coral health.
Others are less choosy and may feed on other small animals or algae around the reef, or even out in the deeper water.
If you find a reef is dominated by one or two species you may be able to draw some conclusions about the reef type in that area.
Butterflyfish are often seen as the romantics of the reef, as many species are normally found in pairs, and the pairing will last for life.
A few species are solitary and normally found alone, while a very few species form large schools.More info here…
Butterflyfish depend on living coral for shelter and food.
Many species feed directly on living coral polyps, and others on the tiny invertebrates around the corals, or on the tube feet or tentacles of larger invertebrates such as Sea Cucumbers, Starfish, Sea Anemones or Jellyfish.
Butterflyfish are in the family Chaetodontidae.
They have deep, compressed bodies (oval-shaped when side on, thin when head on).
They have small, pointed mouths, with small, brush-like teeth.
Hard corals come in a variety of shapes, sizes and colours.
Corals are small animals (polyps) that are closely related to sea anemones and jellyfish.
Most corals create colonies, by growing a large rocky skeleton that we see as a solid coral rock. The soft bodied polyps live in the outer edge of this skeleton, on top of the empty skeletons of previous generations. Only the outer layer of a coral boulder is alive.

From Wikipedia, the free encyclopedia
The butterflyfish are a group of conspicuous tropical marine fish of the family Chaetodontidae. Found mostly on the reefs of the Atlantic, Indian and Pacific Oceans, butterflyfish are fairly small, most from 12 to 22 cm in length. The largest species, the lined butterflyfish, Chaetodon lineolatus, grows to 30 cm. There are approximately 115 species in eleven genera. A number of species pairs occur in the Indian and Pacific oceans and their taxonomy has often been confused by whether these should be considered species or subspecies. Recent work using DNA sequences has resolved many of these questions.  They should not be confused with the freshwater butterflyfish of the family Pantodontidae.
Butterflyfish is named for their brightly coloured and strikingly patterned bodies in shades of black, white, blue, red, orange and yellow (though some species are dull in colour). Many have eyespots on their flanks and dark bands across their eyes, not unlike the patterns seen on butterfly wings. Their deep, laterally compressed bodies are easily noticed through the profusion of reef life, leading most to believe the conspicuous coloration of butterflyfish is intended for interspecies communication. Butterflyfish have uninterrupted dorsal fins with tail fins that may be rounded or truncated, but are never forked.
The family name Chaetodontidae derives from the Greek words chaite meaning “hair” and odontos meaning “tooth.” This is an allusion to the rows of brush-like teeth found in their small, protrusile mouths. Butterflyfish closely resemble the angelfish of the family Pomacanthidae but are distinguished from the latter by their lack of preopercle spines (part of the gill covers).
Their coloration also makes butterflyfish popular in the aquaria hobby. However, most species feed on coral polyps (corallivores) and sea anemones; this poses a problem in most reef tanks where a delicate balance is to be maintained. Species kept in the hobby are therefore the few generalists and specialist zooplankton feeders.
Generally diurnal and frequenting shallow waters of less than 18 m (some species found to 180 m), butterflyfish stick to particular home ranges. The corallivores are especially territorial, forming mated pairs and staking claim to their own head of coral. Contrastingly, the zooplankton feeders will form large conspecific groups. By night butterflyfish hide amongst the crevices of the reef and exhibit markedly different coloration than they do by day.
Butterflyfish are pelagic spawners; that is, they release many buoyant eggs into the water which then become part of the plankton, floating with the currents until hatching. The fry go through what is known as a tholichthys stage, wherein the body of the postlarval fish is covered in large bony plates extending from the head. This curious armoured stage is seen in only one other family of fish; the Scatophagidae (scats). The fish lose their bony plates as they mature.
