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
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.
