How to recognize Aphyocharax rathbuni ?

Aphyocharax rathbuni measures between 4 and 5 cm. Given its small size, this species is commonly referred to as a "dwarf" animal. This fish is bicolore with a predominantly rouge and argent body.

Sexual dimorphism

The females have a more rounded abdomen than the males, they are generally stockier. This characteristic is exacerbated in the period of reproduction.

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
    80 liters
  • Population min
    8
  • Temperature
    20 - 26 °C
  • pH (acidity)
    5.5 - 7.5

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.

In nature, animals are subject to weather conditions and live in waters with variable characteristics. The recommendations offered by our team for aquarium maintenance are a guidance and cannot be assimilated to scientific datas.

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 Aphyocharax rathbuni

Aphyocharax rathbuni is a species which lives naturally at a temperature between 20 °C and 26 °C. For proper maintenance, the temperature should never exceed the 29°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.

The breeding of this species is accessible on condition of being well informed about its needs in aquarium . Any cohabitants must be chosen with care to avoid the loss of animals.

This species is very rare in the aquarium trade. Instead, it is maintained by knowledgeable aquarists who own and breed individuals from wild origin strains. If you want to get this species, we advise you to contact specialized clubs. }Specimens from long time breeding are a bit easier to breed but you have to respect the particular water parameters.

Cohabitation & Environment

Being a living in shoals fish, it is advisable to install at least 8 individuals in an aquarium of 80 liters minimum. Group maintenance is a prerequisite to ensure their well-being. Lonely individuals tend to quickly become stressed and become especially susceptible to disease. Although sometimes certain groups can "merge", mixing several gregarious species living in the same zone of life is not recommended if the volume is not consequent.

Aphyocharax rathbuni is a peaceful species that generally does not exhibit behavioral problems in a community aquarium.

It should be noticed that this species should not be kept with large crustaceans or fish, as it would become a prey of choice. Smaller species should preferably be inserted in the aquarium some time before the larger ones. Moreover, if you want to breed it, it is better to put them in a specific aquarium.

Tips for feeding

Aphyocharax rathbuni is omnivorous.

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.
