Deontology

Respect for wildlife

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
  700 liters
• Population min
  3
• Temperature
  23 - 28 °C
• pH (acidity)
  7.5 - 8.5

Characteristics

General reminders

Before acquiring an animal

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.

Freshwater conditions

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.

Setting up your aquarium

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.

Testing water parameters

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.

Water changes

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.

Precautions to be taken with chlorine

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 Otopharynx selenurus

Otopharynx selenurus is a species which lives naturally at a temperature between 23 °C and 28 °C. For proper maintenance, the temperature should never exceed the 31°C for long periods. Otopharynx selenurus is sensitive to abrupt changes in parameters as well as to chemicals. Its acclimation in an aquarium must be done with special care to prevent it from developing diseases or weaknesses. Nitrate levels should remain below 25mg/L. To keep the water clean and unpolluted, plan on changing 20% to 30% of the water volume each month.

Maintenance difficulty

Otopharynx selenurus is a species whose maintenance is rather reserved for informed aquarists . It can only be successfully carried out by carrying out a minimum of documentation work. Special husbandry conditions can easily lead to the death of the species or other animals.

Cohabitation & Environment

Being a living in small groups fish, it is advisable to install at least 3 individuals in an aquarium of 700 liters minimum (for 140 cm of frontage). Group maintenance is a prerequisite to ensure their well-being. Lonely individuals tend to quickly become stressed and become especially susceptible to disease.

Otopharynx selenurus may show signs of aggression. In general, this species should not be mixed with large territorial species or other overly aggressive species, in order to avoid possible stress or even injury.

However, it can coexist with other species with a peaceful temperament and with some slightly territorial neighbors, as far as the volume of the aquarium allows. It is important to avoid that two territorial species share the same living area in an aquarium of insufficient volume.

This fish being polygamous, the male must always be maintained with several females. A ratio of three females to one male seems to be a good compromise for the constitution of the group.

Basic water maintenance

Otopharynx selenurus naturally living in basic water, the presence of limestone rocks such as millstone or travertine will improve its environment. It is also advisable to add sand with a contribution of specific salts to stabilize the pH, to be gauged according to the hardness of the water used.

Tips for feeding

Otopharynx selenurus is omnivorous with carnivorous tendency.

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.

Reproduction protocol

• Maintenance difficulty
  moderate
• egg-laying protection
  Yes

Reproduction of this species in an aquarium is considered moderate. Ideally, it takes place at a temperature of around 25 ° C for a pH of 8 .

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.
