TAXONOMY
Kingdom:Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Chaetodontidae (Butterflyfishes)

Genus/species: Chelmon rostratus

GENERAL CHARACTERISTICS: All species have a deep, laterally compressed body with a continuous dorsal fin and distinctive rounded anal fin. Many have a band across the eye and/or a false eyespot, patterns that may lure a predator to attack the tail
rather than the head.
The C.rostratus has a whitish body with 4 vertical orange bands and a black false eyespot on the terminal orange band. The snout is long with beak-like mouth.

Length to 19 cm (7.5 in).

DISTRIBUTION/HABITAT: They are found in the Andaman Sea to Papua New Guinea, north to Ryukyu Island, south to Northwest Australia and Great Barrier Reef in estuaries and coastal reefs.

DIET IN THE WILD: Though the diet of the Copperband Butterflyfish is well documented, they are believed to feed heavily on tube worms and small crustaceans using their long snout for prying into the crevices of coral.

REPRODUCTION: Butterflyfishes unlike most fishes are usually monogamous, forming pairs and are often seen swimming together.   They are broadcast spawners an external method of reproduction where the female releases unfertilized eggs into the water. At the same time, a male release sperm into the water which fertilizes the eggs which contain a drop of nutrient oil to sustain the embryo  developing inside the egg case. Oil also provides buoyancy, so the eggs float and drift with the current.  Planktonic eggs hatch within a few days becoming the larval stage lasts from several weeks up to 2 months.  During the late larval stage the head and body are covered with bony plates which mature into small fry fish.

Copperband Butterflyfish8387609757_79c1b099a9_b

CONSERVATION: IUCN; Least Concern (LC)

REMARKS: The Copperbanded Butterflyfish is a food fish marketed locally. and is reported to be “not good” from a culinary standpoint.

Color of Life, Color Conceals.   The Copperband Butterflyfish helps conceals its head by having a vertical line through the eye which matching the 3 other vertical orange bands. A large false spot on its terminal orange band (a less vital portion of its body) confuses predators.

TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch likes)
Family: Chaetodontidae (Butterflyfishes)

Genus/species: Hemitaurichthys polylepis

GENERAL CHARACTERISTICS:They have a deep, laterally compressed body, a single, un-notched dorsal fin, and a small mouth with brushlike teeth. The color of the head is brown to black. The body has a large white pyramid-shaped area on its side and its scales are pearlescent. The dorsal and anal fins are yellow; caudal fin white.

Length up to 18 cm (7 in)

8673542491_279f027703_k

DISTRIBUTION/HABITAT: Eastern Indian,  Western and Central Pacific Oceans. Among outer coral reefs usually close to drop offs, at depths 3–60 m (9-180 ft).

DIET IN THE WILD: Pyramid Butterflyfish are planktivores that aggregate in the water column. Unlike many other butterflyfishes, this species does not feed on coral polyps, so is considered a good choice for aquaria with live corals. 

REPRODUCTION: Oviparous. Form pairs during breeding.

CONSERVATION: Least Concern (LC)

REMARKS: Occur in large schools that feed several meters above the edges of steep outer reef slopes.

TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Chaetodontidae (Butterflyfishes)

Genus/species: Forcipiger longirostris

GENERAL CHARACTERISTICS: Yellow with black upper head and silvery white below; extremely elongated snout; black spots on breast, spot on anal fin below tail base. Individuals occasionally turn dark brown, a color phase that does not seem to be related to sex or reproduction. 

Length up to 22 cm (8.5 in)

DISTRIBUTION/HABITAT: Indo-Pacific from East Africa to Indonesia, Philippines, Hawaii, French Polynesia Japan to Great Barrier Reef. Non-migratory; usually found, in the outer reefs from 3–70 m (9-210 ft).

DIET IN THE WILD: F. longirostris has elongate jaws to feed on a wide range of predominantly attached, benthic invertebrate prey. It is thought that the ‘‘manipulation’’ method is used by butterflyfishes to grip and remove pieces from polychaetes, nemerteans, corals, ascidians, echinoids, hydroids, and other attached prey.
Suction is used when feeding on mobile prey.

REPRODUCTION : Monogamous; form breeding pairs. Ovoviparous, broadcast spawners, with eggs and larvae passing through an extended planktonic stage.

CONSERVATION IUCN Red list Least Concern (LC)

Genus/species: Heniochus diphreutes 

GENERAL CHARACTERISTICS: Their color is white with pair of black bands, second band terminating at end of anal fin. There is an elongate dorsal fin filament.

DISTRIBUTION/HABITAT: Indo-Pacific; widely distributed from the Red Sea and the east coast of Africa to Hawaii on outer reef slopes, 15–210 m (50-690 ft.) in the tropics typically in cool upwelling water.

DIET IN THE WILD: Zooplankton.

REPRODUCTION: Oviparous forming pairs during breeding.

CONSERVATION: IUCN Least Concern (LC)

3266275817_271223e95d_o

REMARKS: Form large schools, and also occur in small groups or solitary. Their elongate dorsal fin filament, gives this group of fishes their “bannerfish” moniker; is the fourth dorsal spine. Often called the “false” Moorish Idol for its markings similar to the Steinhart’s iconic species; however, the flowing dorsal fin and larger size of the Idol are distinctive differentiations.

Genus/species: Chaetodon lunula

3120146362_b277962165_o

GENERAL CHARACTERISTICS: Yellow-orange with darker upper half of the body. It has a black patch around its eyes (similar to a Raccoon masked face) with a broad white stripe posterior to it. Two black stripes bordered in yellow reach from the white stripe to the dorsal fin. Black markings around its eyes suggestive of a Racoon. Maximum length to 8 inches.

DISTRIBUTION/HABITAT: From East Africa throughout the Indo-Pacific, south to Australia, east to Hawaii. Found in shallow reef flats of lagoon and seaward reefs, to depth of 30 m (98 ft).

DIET IN THE WILD: Nocturnal omnivore feeding on coral polyps, worms, crustaceans, plankton, algae

REPRODUCTION: Oviparous forming pairs during breeding.

CONSERVATION: IUCN Least Concern (LC)

REMARKS: Chaetodon means “bristletooth,” and has a dental array well-suited to its diet. Has a great fondness for coral polyps, which makes our Steinhart denizen a better fit for the Reef Lagoon which contains no corals. There it feeds on other invertebrates.
