Breeder ID: AMPOCE-041599-NESJEF-007

Date received: 4/15/99

Identification: Amphiprion ocellaris (Cuvier, 1830)

Geographic origin: Indo-Pacific


Taxonomy: (after I.C.Z.N.)

Kingdom Animalia

Phylum Chordata Subphylum Vertebrata

Class Osteichthyes

Order Perciformes Superorder Teleostei

Family Pomacentridae

Genus Amphiprion

Species ocellaris (Cuvier, 1830) 


Description: Orange body with three distinct white body stripes (or bars ); the head stripe is anterior to the eye and continues down across the preoperculum. The body stripe extends from between the spinous (anterior) and soft-rayed portion of the dorsal through the body to the abdomen just in front of the anal fin with the center of the stripe “bulging” towards the head. The tail stripe covers the caudal peduncle. The stripes have narrow black margins. The fins are rimmed in black just prior to a small non-pigmented edge. A. ocellaris is commonly confused with A. percula which is “shorter” in height (A. Percula is 3.1 – 3.3 in head-length compared to 2.1 – 2.9 head-length for A. ocellaris). Additionally A. ocellaris has 11 dorsal spines (rarely 10) compared to A. percula having 10 dorsal spines (rarely 9). Maximum size is listed by most sources at 90 mm – 95 mm, however, Burgess, 1988, lists 150 mm. Females are typically larger than the male.

Distribution is from the Indo-Malaysian Archipelago, Philippines, southward to northwestern Australia and northward to the Ryukyu Islands. The symbiotic relationship of clownfishes is well documented and this species is found with Heteractis magnifica (Qouy & Gaimard, 1833), Stichodactyla gigantea (Forsskål, 1775) and S. mertensii (Brandt, 1835).


Length of time in captivity male: 3 months

Size male (mm): 37 – 50

Length of time in captivity female: 3 months

Size female (mm): 76

Physical differences: Male is smaller. Female is much larger, more robust, especially in abdomen.

Adult diet: Gelatin based food (Hoff, 1996), seafood paste mix (Moe, 1989), flake food, beefheart, newly hatched brine shrimp. 2 – 3 times per day

Pre-spawning activity: Female becomes rotund in abdomen.

Time spawning began: mid – l;ate afternoon

Area spawning occurred: upper inside of clay flower pot.

Frequency of spawning: ~ 2 weeks

Egg Description: orange eggs spread over small area (~ 37 mm x 64 mm)

Approximate quantity: ~250

Size: not indicated

Incubation: 7-8 days

Time hatching occurred: ~ 1 hour after dark

Size at hatching: not indicated

Yolk sac present? No

Egg changes / development: Color changed to brown after 2 days, then purpleish after 4 -5 days, then silver colored (larval eye) on day 7.

Transfer / removal method: not indicated 


Spawning tank size (liter): 82 (partioned section of a 260 liter tank (70 gallons)

Sides of tank covered? No

Lighting & photo period: 2 fluorescent strip lights, standard shoplight fixture. 12 hour ~ 20 – 25 cm from surface

Filtration: Wet/dry, outside box filter Aquaclear 2000®, protein skimmer (with ozone)

Additives and dosages: Coralife® ASW and trace elements (as per labeled instructions. 25% water change 4 – 6 weeks

Water temperature: 79 – 81ðF

Specific gravity: 1.020

pH: ~ 8.3

Nitrate: 5 – 10 ppm


Fry development / changes: Silvery larvae

First Food Offered: Brachionus plicatilis, 3 times per day

Second Food Offered: Pulverized flake food at day 5, 3 x day.

Survival: not indicated, but at time of report a totla of 250 – 300 juveniles have been raised.

Development description: Metamorphosis 9 days after hatch 


Rearing tank size (liter): 27

Sides covered?: Yes, all sides black

Lighting & photo period: ambient

Additives & doses: Change water every 4- 5 days ( 15 – 20%)

Water parameters: same as adult (spawning) tank

Comments: The original male died and was replaced with another male and spawning began 2 weeks later. Nests were laid as solid masses, but after 2 – 3 days eggs began dropping away. No fungus observed and Hoff suggests that the age of the female may be the cause. The yield from each nest was poor. 3 months after the introduction of the new male, the female died (jumped out of tank). Another larger fish has been introduced.  


Original description: Cuvier first described Amphiprion ocellaris in 1830 in Cuvier & Valenciennes 1830:399 in the Hist. Nat. Poiss. V.5 reference 999, from a specimen collected in Sumatra, Indonesia. Validated by Ida in Masuda et al., 1984 and Allen in 1991.

Synonomy:

Amphiprion melanurus, Cuvier in Cuvier & Valenciennes 1830:400 in Hist. Nat. Poiss. v. 5; ref.
999, From a single (Holotype ) specimen also collected in Sumatra, Indonesia. Synonym of
Amphiprion ocellaris Cuvier 1830 (Allen 1991:237 [ref. 19344]).

Amphiprion bicolor, Castelnau 1873:92 in Proc. Zool. Acclim. Soc. Victoria v. 2; ref. 758. From
a single (Holotype) specimen collected near Darwin, Northern Terr., Synonym of Amphiprion
ocellaris
Cuvier1830 (Allen 1991:237 [ref. 19344]).

Vernacular name: Common clownfish, Ocellaris clownfish, Anemone Demoiselle, False Clown Anemonefish, False percula clownfish

Word origin: Amphiprion is from the Greek roots amph, -i, -o, meaning Around, on both sides; double, and -prion which means a saw. The genus ocellaris is confusing; the Latin root o, meaning an egg; cell, -a, -i, meaning a cell; or perhaps ocell, =us, meaning little eye and -ris meaning laughter (little laughing eye?). The synonym melanurus is composed of the Greek roots melan, -o, meaning black; and ur, =a, -o, meaning tail (thus black tail). The synonymbicolor means two colors (bi = two).
