Amphiprion barberi, Allen, Drew & Kaufman, 2008
This is a new species of sea anemonefish described only in 2008.
Keep like other sea anemone fish !
The following host anemones are known: Entacmaea quadricolor (Rüppell & Leuckart, 1828) or Radianthus crispa. Occurrence at 6-10 meters.
Unfortunately, this small anemonefish species is very rare to find in the trade.
The new species of damselfish: Amphiprion barberi, is described based on 46 specimens ranging from 16.3 to 85.8 mm SL caught at depths from 2 to 10 meters over coral reefs of Fiji, Tonga and Samoa.
Sex and mating.
Anemonefish are protandrous hermaphrodites, meaning that life begins as a male. If two juveniles of the same size are present, then the more dominant anemonefish will develop into a female. If two females of the same size are placed together, then the weaker female will form back into the male, but this will take some time and there will be fierce fighting. The reversion can take several weeks, and during this time the more dominant female will keep putting the pressure on the weaker female until the sex has changed.
If there are several anemonefish in the aquarium and the dominant female dies, the previously dominant male will revert to female and a previously suppressed animal will move up to the dominant male. By this adjustment the main task, the spreading of the "own genes" on fast way remains.
Once the disputes have settled and the roles are established, the female will continue to grow. The difference in size from male to female is about 1-3 cm depending on the initial size of the species.
Breeding information:
Spawning interval*: 14 days
Spawn size**: 3 x 3 cm, depending on the conditions
Number of larvae**: approx. 100 - 200 pieces
Clutch color day 1: ??
Fish larvae: are phototactic (decreases with the age of the larvae)
First food: Brachionus plicatilis - enriched or pelagic (free-swimming) copepods
* The water temperature influences the number of fertilized eggs and the spawning period (with a difference of e.g. 1° C, the difference can be ± 2-3 days) and, in the case of gonochoristic (separate-sex) fish or shrimp, the sex. If the temperature is below the usual regional temperature, mainly female larvae will hatch from the clutch, above this temperature mainly male larvae will hatch. Furthermore, the aquarium conditions (e.g. light duration, density) can also influence the sex.
** The spawning size or the number of larvae depends on several factors - age and condition of the parent animals, water conditions, food quality, stress factors and the dissolved oxygen content.
It is closely related to Amphiprion melanopus, which is widely distributed in the western Pacific.
The two species show distinct differences in color pattern: among other things, the trunk of Amphiprion barberi is mainly reddish orange, while that of Amphiprion melanopus is dark brown or blackish.
In addition, the adults of the new species have fewer spinules on the rows above the gill cover, 11 to 19 compared to 19 to 26.
The genetic data presented here also support a separation of the two species.
