Amphiprion allardi – Twobar Anemonefish
Amphiprion allardi was officially described in 1970 by Klausewitz. The family name Amphiprion can be broken into two ancient Greek words. Ampi means on both sides and prion means saw.
This anemonefish can reach a total length of around 15 centimeters. The color of adults is dark brown to black with two white or bluish / white vertical stripes on top. The caudal fin is pale yellow to whitish. The other fins are yellow. The caudal fin is rounded.
They resemble Amphiprion chrysopterus but are not found together in the wild and can therefore easily be separated. Amphiprion latifasciatus is also very similar. However, this species has a wider white band on the flank and a forked caudal fin.
Amphiprion allardi lives in symbiosis with a number of anemones: Entacmaea quadricolor; Heteractis aurora; Stichodactyla mertensii.
Like all other Anemone fish, Amphiprion allardi is a sequential hermaphrodite. All fry of this species are born genderless. After a while they turn into a male. This species can form a couple or live as a group in an anemone, depending on the size of the anemone. The largest animal is the female. When the female dies, the largest and strongest male changes into a female. With this they ensure that they can always reproduce.
The Amphiprion allardi distribution range is located around the east coast of Africa, around Madagascar and to the east in the Western Indian Ocean towards Mauritius. They inhabit the coral reefs at a depth of 1 to 30 meters.
In the wild, Amphiprion allardi feeds on the food particles caught by the anemone. They also eat zooplankton and small invertebrates. A very small part of their diet consists of algae. In the aquarium you can feed them with a mix of different types of food such as artemia, flakes, frozen food etc.
It has been seen in the aquarium that Amphiprion allardi actually feeds the anemone. This involved pieces of food that were too large for the fish.
A pair of Amphiprion allardi can be kept in a 200 liter aquarium. Make sure there is sufficient current. They feel most at ease in a suitable anemone. Give them an Entacmaea quadricolor, Heteractis aurora or a Stichodactyla mertensii.
The temperature of the water for this species can be between 22 and 27 degrees Celsius. It is a fairly hardy species that is easy to care for. They are therefore also suitable for the beginning seawater aquarist.
A group of anemone fish has a very strict hierarchy. The largest and strongest specimen is always female. To reproduce, the female will only mate with the second fish in rank. This is the largest and strongest male. The other males do not participate in the mating ritual.
A couple deposits the eggs on the substrate right next to their anemone. The eggs are sticky and stick to the substrate. After spawning, the male guards the eggs and aerates them. They are very aggressive when guarding the eggs. All fish that come within a few meters of the nest are attacked. They don’t even shy away from attacking divers. Their bite is not very painful. You can compare it to quickly pinching your skin.
This species is bred in captivity. Ask in the store for captive bred fish so that they do not have to be caught in the wild. Unfortunately, they are not always available.
