TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Pomacentridae (Damselfishes, Chromis, Aneomonefishes)

Genus/species: Amphiprion latezonatus

GENERAL CHARACTERISTICS:  The very wide mid-body bar is much narrower at the top than at the bottom. The body is dark brown with three white bars, middle bar very wide, more than twice the width of the mid-body bar of most other anemonefishes. A. latezonatus often has bright blue markings on the upper lip and the edges of the bars. Has blue lips as well as a broad bar on the sides of the body. The dorsal fin may be orange or yellow. The caudal fin has a pale posterior margin.

Length up to 15 cm (6 in)

DISTRIBUTION/HABITAT: The Wide-Band Clownfish is found on the Western Pacific: Australia and New Caledonia inhabiting rocky and coral reefs. Depth to 5-45 metres (16-150 feet).

DIET IN THE WILD: Carnivore, feeds mainly on planktonic crustaceans (copepods, mysis, and shrimp larvae and some algae.

            Juveniles below note the different color.  NOT CURRENTLY ON EXHIBIT

REPRODUCTION: Clownfish are oviparous with distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs.
Protandry refers to organisms that are born male and at some point in their lifespan change sex to female. Protandrous animals include clownfish. If the female clownfish is removed from the group, such as by death, one of the largest and most dominant males will become a female. The remaining males will move up a rank in the hierarchy.

Juveniles below note the different color.  NOT CURRENTLY ON EXHIBIT

REMARKS: Associated with the anemone Heteractis crispa in the wild.

Order: Perciformes (Perch-likes)
Family: Pomacentridae (Damselfishes)
Subfamily: Pomacentrinae

Genus/species: Chromis viridis

GENERAL CHARACTERISTICS: Adults are iridescent apple-green and light blue. Courting males develop blackish dorsal rays and upper pectoral rays. Caudal fin deeply forked with very long, trailing tips.

Length up to 9 cm (3.5inches)

DISTRIBUTION/HABITAT: Indo-Pacific.among reef flats, shallow lagoons, sheltered seaward reefs to 12 m (39 ft). Huge aggregations above branching corals, often well above the bottom. Swarms of juveniles occur above smaller isolated coral heads.

DIET IN THE WILD: Plankton.

DISTRIBUTION/HABITAT: Blacktail Damselfish are found in the Western Pacific among branching corals in inshore and lagoon reefs to 68 m (210 ft).

DIET IN THE WILD: Omnivore; feeds on plankton, including larval shrimps and crabs, algae, ostracods, amphipods, pelagic tunicates, copepods, and fish eggs.

Dascyllus melanurus4437575636_cc28be23c1_b

REPRODUCTION: The Blacktail Damselfish is oviparous, with distinct pairing during breeding  The eggs are demersal and adhering  to the substrate  Males guard and aerate the eggs. Recent research suggests this species is a protogynous hermaphrodite.

CONSERVATION: IUCN Red List Not Evaluated

REMARKS: They hide among Acropora branching corals when threatened, though adults have an aggressive temperament.

Genus/species: Premnas biaculeatus

Female below

GENERAL CHARACTERISTICS: Juveniles orange-colored; color deepens with age. Male smaller, bright red with three brilliant white bars, sometimes barely visible. Female becomes maroon or almost black with subdued bars. Note the conspicuous spine on cheek below the eye.

 Length to 17 cm (6.75 inches). 

DISTRIBUTION/HABITAT: Indo-West Pacific: Indo-Australian Archipelago including India, Burma, Thailand, Malaysia, Indonesia,Philippines, New Guinea New Britain, Solomon Islands, Vanuatu, and northern Queensland, Australia.  Premnas biaculeatus is found in lagoons and seaward reefs, 1–16 m (3.25-52.5 ft) exclusively with the sea anemone Entacmaea quadricolor. They are usually in pairs.

DIET IN THE WILD: Zooplankton and algae.

REPRODUCTION: Oviparous. Males and females guard and aerate the eggs. Protandrous hermaphrodite, In the case of the death of the female, the second largest changes from male to female. Size difference is maintained in order to avoid subordinates becoming a threat to the highest ranking male.; female is to about 2–3 times the size of her male partner.

LIFESPAN: 6 to 10 years in the wild.

PREDATORS: Wrasses

CONSERVATION: IUCN: Not evaluated

REMARKS: P. biaculeatus has a mutualist relationship with Entacmaea quadricolor. The anemone benefits from having spinecheek anemonefish protect them from butterflyfishes, which feed on their tentacles. P. biaculeatus also clean away debris and parasites from the anemone. Spinecheek anemonefish are protected from most fish by the venomous anemones tentacles which do not injure the anemone fish.

Genus/species: Amphiprion perideraion

 

GENERAL CHARACTERISTICS: Pinkish-orange coloration varies in saturation of color by individual. Distinctive narrow white head bar, narrow white dorsal stripe from eyes to tail.

Length: Up to 10 cm or 4 inches in length

DISTRIBUTION/HABITAT: Indonesia to Marshall Islands Southwest Japan to northwest Australia. Found in coral reefs from 3–30 m (10-100 ft).  They pursue a symbiotic life with at least 4 anemone species but most commonly with the large (to 1 m or 3.2 ft. diameter) mature magnificent sea anemone (Heteractis magnifica). Also associates with Heteractis crispa, Macrodactyla doreensis and Stichodactyla gigantea.

DIET IN THE WILD: Zooplankton, primarily copepods, as well as filamentous algae.

REPRODUCTION: Protandrous hermaphrodites. Like all anemonefishes, sex and growth are controlled by the dominant female. Elliptical eggs are laid on rocks close under the host anemone’s mantle. The male fish guards the eggs. Upon hatching the larvae drift in the plankton.

Amphiprion clarkii  

GENERAL CHARACTERISTICS:  To 12 cm (4.75 in). Black to entirely orange with pair of white or pale blue bars. Second bar wide; tail white or yellowish; other fins variably black to yellow-orange. There is also an orange variation: some are entirely pale orange, other than the two white bands; others have a dark patch on rear body.  (See remarks)

DISTRIBUTION/HABITAT: Indo-Pacific: Persian Gulf to Micronesia, New Caledonia and Fiji. Also Southwest Japan to northern Australia. Depth 1–55 meters (3-180 ft.) in outer reef slopes, less typically inhabit lagoons. Symbiotic with 10 species of sea anemones. Non-migratory.

DIET IN THE WILD:  Primarily planktonic copepods and benthic algae.

REPRODUCTION:  Monogamous; oviparous. Fertilization is external; benthic spawners; parents create a nest and male guards eggs. Are protandrous hermaphrodites; all mature as males In the absence of a female, the largest juvenile will mature within 5–6 months into the breeding male. The maturation of the smaller (all male) juveniles is stunted by the adult pair’s presence.

REMARKS: Coloration is apparently influenced by the host sea anemone species. Symbiotic with several anemones found in the Steinhart including Entacmaea quadricolor, Heteractis crispa, H. magnifica.
