DISTRIBUTION/HABITAT: Indo-West Pacific: Red Sea and Natal, South Africa to Niue, north to Japan, south to Australia. Found above coral outcrops or patch reefs of clear lagoons, channels, or outer reef slopes. depth range 0 – 55 m (170 feet).

DIET IN THE WILD: Zooplankton

REPRODUCTION: A protogynous hermaphrodite. All start life as females. The dominant fish will turn into a male, changing sex, and color and pattern. The male keeps a harem of several females.

CONSERVATION:  Not evaluated

4482852401_4ab3a860ab_b

GENERAL CHARACTERISTICS: Unlike its cousins the Pseudanthias species, the Flathead Anthias has a deep body and elongate pectoral fins that extend back as far as the posterior part of the anal fin.. Predominantly pink, with heavy yellow-to-orange scale margins and facial markings. Max.length: 10 cm (4 inches).

DISTRIBUTION/HABITAT: Western Pacific. Found near coral reefs usually at depths of 18 m (60 feet) or more, either solitarily or in small haremic groups; also found near caves, ledges, and drop-offs, usually close to crevices where they retreat if threatened.

DIET IN THE WILD: Zooplankton

REMARKS; First described in 1949 as a hawkfish in the family Cirritidae but in 1978 it was placed in the subfamily Anthiinae (Anthias).

Genus/species: Pseudanthias tuka

Male below

Purple AnthiasI MG_2808

GENERAL CHARACTERISTICS: Sexes bichromatic. Both sexes are a deep pink to purple; however, females have a bright yellow stripe on the back extending onto the caudal fin. Males have a purple blotch on the base of the dorsal fin, elongated fin rays, and a pointed snout Max. size: 12 cm.

DISTRIBUTION/HABITAT: Indo-Pacific: Philippines, Bali, Solomon Islands, Great Barrier Reef, Japan. Habitat: Favor strong currents along the edge of drop-offs and steep outer reef slopes at depths of 30 m or more.

Female below

DIET IN THE WILDt: Planktonic crustaceans and fish eggs.

REPRODUCTION: As in all Anthias species, if a dominant male dies, the largest female will usually change into a male and take his place.

REMARKS: Usually found in large aggregations with many more females than males.

TAXONOMY
Class: Actinopterygii (Ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Serranidae (Sea basses: groupers and fairy basslets)
Subfamily: Anthiinae (Anthias)

On exhibit:

Pseudanthias dispar – Redfin anthias
P. lori – Lori’s anthias
P. randalli – Randall’s anthias* (not currently on exhibit 1-31-14)
P. tuka – Yellowstrip anthias
P. ventralis ­– Longfin anthias
Serranocirrhitus latus  – Sunburst anthias ( a closely related genus)
 

 DISTRIBUTION: Pseudanthias species are found throughout the Indo-Pacific region. Many of the some 64 species have fairly wide distribution.

 HABITAT: During the day, they are found along the upper reef face in areas of strong current. At night, when predators threaten, they seek shelter in the reef’s caves and crevices.

GENERAL CHARACTERISTICS: Pseudanthias are small, fast-moving, colorful fishes. The male and female pseudanthias, like many members of the family Serranidae display gender-specific body shape and/or color. The male of P. dispar, for example, has a bright red dorsal fin and more pink and blue on the head and sides than the generally yellow female. The male yellowstripe anthias is a deeper purple overall than the female that sports a bright yellow stripe on the back not seen in the male.

DIET IN THE WILD: Plankton and fish eggs.

REPRODUCTION: All are sequential protogynous hermaphrodites. Protogynous literally means “first female,” a reference to the fact that all individuals are born as females, but a few, usually the largest females, will in time will change sex and develop male sex organs. The sex change, which can be completed in only a few days, is triggered by the loss of the dominant male, usually to predation.

 This reproductive strategy may confer at least two benefits: first, many young, healthy females serviced by a few large males means that in a given aggregation of fish more eggs, which are larger and therefore more energetically expensive, are produced.  Sperm, especially that produced by a large male, is plentiful enough to fertilize the eggs of even a large group of females. Also, the large males are extremely territorial and protective of their harems.

PREDATORS: These small fish are snack food for many larger predators. Life span of most species is about 3­–5 years.

 

REMARKS: The Steinhart displays several other fish families besides serranids with members that practice protogynous hermaphoditism, including wrasses, angelfishes, gobies, found in a number of tanks. Bocalo, the giant sea bass, is the Steinhart’s most notable practitioner
