How to recognize the jaguar catfish ?

This fish has the particularity to possess several pairs of barbels, which allow him to search the bottom and to detect the food thus moved.

The jaguar catfish measures between 17 and 20 cm. This fish is bicolore with a predominantly orange, noir and beige body. The also has noir mottling.

Behaviour & Life cycle

  • Sociability
    solitary

    Yes
  • Way of living
    nocturnal

The jaguar catfish is a fish solitary naturally found in the vegetation. This species is carnivorous . This fish lives mainly at night. Usually, it leaves its hiding place and starts to be active once it gets dark.

This species is territorial and does not appreciate the presence of intruders nearby, especially animals with similar behavior. However, the jaguar catfish has little concern for non-territorial animals.

Biotope presentation

The acidification of water comes from the decomposition of plants. This phenomenon changes the color of the water, which tends to turn brown. In some areas particularly rich in organic matter, the water is so dark that it is called "black water".

This species lives near large roots, in which it can find refuge in case of danger. This type of habitat is often found not far from the banks.

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
    300 liters
  • Population min

  • Temperature
    20 - 26 °C
  • pH (acidity)
    4.8 - 6.8

Characteristics

  • Difficulty breeding
    hard
  • Robustness
    tolerant
  • Behaviour
    slightly aggressive
  • Availability
    rare

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 the jaguar catfish

The jaguar catfish 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 jaguar catfish 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.

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.

Barbel fish

Cohabitation & Environment

In a community aquarium context, this species should be kept in a minimum volume of 300 liters.

The jaguar catfish 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.

Acid Water Maintenance

The jaguar catfish living naturally in acidic water, generally in "black" or "sieved" water, the implementation of a filtration on peat is ideal for its balance. Adding decaying leaves and alder fruit can significantly improve living conditions by naturally increasing acidity of some water.

Tips for feeding

The jaguar catfish 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.
