Identification: Amphiprion akindynos (Allen, 1972) Geographic origin: Indo-pacific

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

Duration male(yr): 2.0

Size male (mm): 102

Duration female (yr): 2.0

Size female(mm): 102

Broodstock notes: The female is very timid and movement in the room where the aquarium is causes stress. The pair shares a 40 gal (US) breeder tank with a pair of A. ephippium. The tank is divided in half with an egg crate divider. There is some displaying between the pairs, but never any actual violence.

Adult diet: Frozen prepared foods, frozen Artemia, flake, smelt roe. Fed ywice daily

Pre-spawning activity: not indicated

Time spawning began:1late afternoon

Area spawning occurred: Inside 6″ clay flower pot, rarely on rock beside flower pot.

Frequency of spawning: ~14 days

Egg description: A tight cluster usually on the top inside of flower pot. Approximately 35 – 50 mm in diameter.

Approximate quantity: 150 – 200

Size: not measured but appear to be the same size as A. ephippium but bigger than A. biaculeatus

Egg changes / development: Start off orange, then change to a dark color. Eyes become visible about 2 days befor hatching

Incubation period: ~6 days

Time hatching occurred: 2 hours after dark

Yolk sac present? no

Attracted to light? yes

Newly hatched appearance: Larvae are very weak and can barely swim and settle to the bottom of the tank. The strong minority are attracted to light. Similar to A. ephippium larvae, large eyes.

Transfer / removal method: Larvae moved to a 37 Liter (10 gallon) tank) No details provoded.

Spawning tank size (liter): (40 gallons) (36″ L x 18″ W x 15″ H)

Lighting & photoperiod: ambient, 12 hours

Filtration: Aquaclear® 300

Additives and dosages: Artificial seawater, 50% monthly changes

Water temperature (F): 77-81ºF

Specific gravity: 1.023

pH: 8.3

Nitrate: not measured

Fry development / changes: metamorphosis at day 8 – 9

First food offered: Rotifers, fed with twice daily

Second food offered: Newly hatched Artemia. Day 4

Survival 1st week: 1% In 8 spawnings only 2 raised to adult. Both from same spawn

Rearing tank size (liter): 37 (10 gallon) (20″ L x 10″ W x 12″ H)

Sides of tank covered? no

Lighting & photoperiod: f15 watt fluorescent. 12 hours

Filtration: Aeration only until metamorphosis, then sponge filter

Additives and dosages: Water from adult tank. 20% daily changes for first 2 weeks, then 20% weekly

Water temperature (F): same as parent tank

Specific gravity: same as parent tank

Comments: My experience is that the larvae are very weak and most not able to swim at hatching. My “best guess” is that the parents need feeding more than twice per day.
