How to recognize the mauritian anemonefish ?

Amphiprion chrysogaster is easily recognizable by its almost black dark brown color and its 3 white stripes. The lower body and anal fins are yellow-orange.

It bears strong resemblance to the Amphiprion fuscocaudatus (Seychelles) where only the tail differs with stripes rather than a solid dark tail for the Amphiprion chrysogaster. Similarly, the Amphiprion tricinctus (Marshall Islands) has a spot on the base of the tail narrower than that of the A. chrysogaster.

Sexual dimorphism

The female is larger than the male.

Behaviour & Life cycle

  • diet
    carnivorous
  • Sociability
    living as a couple
  • territorial
    Yes
  • Way of living
    diurnal

The Mauritian anemonefish lives in colonies among corals and anemones. Although slightly territorial, this fish generally behaves peacefully with other species. It feeds on small plants and microorganisms on the tentacles of shallow anemones.

Reproduction

  • Reproduction
    ovipare qui pond sur substrat découvert
  • Hermaphrodite
    protandric

Amphiprion chrysogaster is an oviparous fish that spawns on exposed substrate. The parents take turns oxygenating the eggs by agitating them throughout the development. After hatching, the fry are carried into the pelagic zone by marine currents.

Harmless species

This species does not represent any particular threats to humans when encountered in its natural environment.

Main recommendations for fishkeeping

Deontology

In order to preserve wildlife, if you acquire this animal, it must not be released into the wild. See also, the Fishipedia charter.

Fishipedia supports the practice of responsible and environmentally friendly aquarium keeping. We encourage maintenance if it is motivated by a desire to understand the biological functioning of living things and if it is done with respect for animal life.

We believe that aquaristics is an opening to the discovery of aquatic environments, especially freshwater, and that this knowledge is necessary to better protect and respect these environments. Logically, we refute the compulsive purchase of animals that would not find a sufficient and / or adapted place in the host aquarium.

Our recommendations

  • Min volume
    200 liters
  • Population min
    2
  • Temperature
    22 - 28 °C
  • pH (acidity)
    8.2 - 8.4

Characteristics

  • Difficulty breeding
    easy
  • Robustness
    robust
  • Behaviour
    peaceful
  • Availability
    occasional

General reminders

It is strongly advised to read the complete dedicated file and to get information on the feedbacks of maintenance of the envisaged animal, this to avoid any potential conflict whose end result is generally the death of the individual (or the other inhabitants). It is important not to overload your aquarium to limit pollution. This will make maintenance easier.

The realization of a seawater aquarium requires certain knowledge beforehand. Seawater is generally synthetic, consisting of reverse osmosis water and synthetic salt at a level of 33g / liters. It is also possible to take seawater directly (after making sure that the water is not polluted). The operation of a seawater aquarium is done in three phases: the installation of a living stone decoration, the introduction of invertebrates one month later, and the introduction of fish 3 months later. It is essential to wait as long as possible before to introduce the animals so that the micro-fauna has had time to develop well. The balance and the physico-chemical stability are fundamental for the success of this type of tank.

General reminder on maintenance datas

Le démarrage d'un aquarium est une partie primordiale pour l'équilibre et le bien-être des poissons. Lorsque l'on met en eau un aquarium, l'eau passe naturellement par un cycle biologique : le cycle de l'azote. Celui-ci dure environ trois semaines. Tous les 2 jours, nous vous conseillons de tester votre eau jusqu'à ce que le taux de nitrite soit à zéro pendant plusieurs jours d'affilée.

Pour accélérer ce cycle, vous pouvez utiliser un activateur de bactéries comme JBL Denitrol. Cette solution riche en bactéries vivantes et enzymes permet une mise en place rapide du cycle de l'azote. Les poissons peuvent alors être introduits plus rapidement.

Il est important de tester l'eau de son aquarium régulièrement pour maintenir un environnement sain pour les poissons et les autres habitants. Les tests d'eau permettent de mesurer les niveaux de différents paramètres tels que le pH, la dureté totale, ainsi que les taux de nitrates, de nitrites et d'ammoniaque.

Pour réaliser ces tests, vous pouvez utiliser des produits d'analyse spécialisés tels que JBL ProScan qui permet de réaliser un diagnostic de l'eau directement via un smartphone. Il existe également des coffrets de tests plus classiques de bandelettes, comme JBL PROAQUATEST.

En cas d’usage de l’eau du robinet, vous pouvez utiliser un conditionneur d’eau de type Biotopol de JBL pour éliminer les substances nocives comme le chlore, le cuivre, le plomb et le zinc. Les conditionneurs d'eau garantissent une meilleure santé aux poissons et une meilleure croissance des plantes.

Chlorine and chloramine are dangerous for the health of animals. Used to disinfect water, these agents are present in significant quantities in tap water. We recommend using an anti-chlorine agent every time you change the water. In addition to chlorine, treatments and medicines sold for aquarium use sometimes contain dangerous heavy metals in high doses.

Specific needs for the mauritian anemonefish

The mauritian anemonefish is a marine species which lives naturally at a temperature between 22 °C and 28 °C. For proper maintenance, the temperature should never exceed the 31°C for long periods. Nitrate levels should remain below 50mg/L. To keep the water clean and unpolluted, plan on changing 20% to 30% of the water volume each month. In seawater, it is also possible to remove nitrates using one of the following methods: Jaubert, denitrator on sulfur, biopeletts, vodka method.

Breeding this species is accessible to any hobbyist. It is recommended to follow some basic rules and to be rigorous to achieve a good maintenance.

This species is generally available in specialized shops or from aquarium clubs. Specimens that have been bred for a long time are easier to breed, but special water parameters must be respected.

Cohabitation & Environment

In a community aquarium context, this species should be kept in a minimum volume of 200 liters.

Fearful by nature, it is advised not to let the mauritian anemonefish cohabit with large territorial species or with too aggressive fish. It can easily evolve with territorial neighbors with a peaceful temperament or with non-territorial species.

Be careful to plan an adequate space for each territorial species. Each species should have a surface and a decor allowing it to juxtapose its territory with that of its neighbors.

Tips for feeding

The mauritian anemonefish is carnivorous.

This species can eat dry food (flakes, pellets), fresh food and frozen food. To avoid deficiencies, it is recommended to vary the types of food.

You should not overfeed your residents to avoid polluting the water. For most species, it is better to feed a few small portions each day rather than one large meal.

Hybridization risks

In general, it is advised not to mix several species of the same genus or different varieties of the same species, to avoid the risks of hybridization.
