How to recognize Atya gabonensis ?

Atya gabonensis measures between 10 and 15 cm.

Of elongated form, like all the shrimps, it has 5 pairs of legs and a segmented carapace at the level of the abdomen which ends in a tail in fan cut for swimming.

Instead of having claws, this shrimp has a kind of brush with which it filters the water.

    nocturnal

Like all crustaceans, Atya gabonensis molts whenever it becomes cramped in its shell. Before the hardening of its new body, it is more vulnerable and spends a good part of its time hidden. This mechanism, very complex, allows the periodic renewal of the exoskeleton and part of the internal skeleton. It is also during the moult that the females become fertile.

Atya gabonensis is a crustacea living in colonies naturally found on the bottom. This species is planctophage . this crustacea lives mainly at night. Usually, it leaves its hiding place and starts to be active once it gets dark.

n general, this species does not care much about other animals crossing its path.

The cilia located on the legs and tail facilitate swimming, which is done in leaps when the abdominal muscles contract.

This shrimp spends most of its time in strong currents to capture suspended micro-food.

What is its habitat?

Natural environment characteristics

  • Temperature
    24 - 30 °C
  • pH (acidity)
    6.2 - 7.5
  • gh (hardness)
    3 - 12
  • Flow
    Strong

Biotope presentation

Atya gabonensis prefers well oxygenated waters in current areas and rapids. It frequents fast flowing waters where the bottom is strewn with pebbles, wood or leaves carried by the current. It can be found not far from waterfalls .

In their natural habitat, these shrimp only leave their hiding places after dark, when their main predators are no longer out.

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
    140 liters
  • Population min

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 Atya gabonensis

Atya gabonensis is a species which lives naturally at a temperature between 24 °C and 30 °C. For proper maintenance, the temperature should never exceed the 33°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 particularly common in the aquarium trade. Animals from long-term breeding are usually acclimatized at a temperature of about 26 °C in neutral water.

Copper is toxic to many invertebrates. Some fertilizers and aquarium foods contain copper sulfate and should be used with caution. Since Atya gabonensis are sensitive to copper, we do not recommend using these products in any form.

Cohabitation & Environment

Being a living in colonies crustacea, it is advisable to install at least 3 individuals in an aquarium of 140 liters minimum. The maintenance in groups allows to observe its natural behavior within the aquarium. 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.

Atya gabonensis is a peaceful species that generally does not exhibit behavioral problems in a community aquarium.

However, being opportunistic, this species should not cohabit with crustaceans or fish of similar or smaller size because they would in fact become potential prey. Sick species, territorial or sharing the same life zone as this crustacean are the subjects most at risk.

Due to their fragile state during moulting, all crustaceans need an environment provided with hiding places (roots, pebbles, leaves, plants, etc.) to shelter in case of danger. To maintain this type of shrimp, it will be necessary to provide a spacious area, consisting for example of small rocks, and without plants so that it can live according to its habits. Naturally, they can be shy when they arrive in the aquarium, but under the right conditions, they will take their place in their new environment without too much difficulty.

As previously said, Atya gabonensis is a species that lives naturally in the current. Thus, we advise the installation of an oversized filtration system (10 to 20 times the volume of the tank) in order to guarantee a strong current and especially a strong oxygenation. A venturi system will improve the dissolved oxygen rate during summer.

Tips for feeding

Most of the food needs of this shrimp can be met by elements already present in the aquarium. Indeed, naturally, Atya gabonensis feeds on microorganisms by filtering the water. Just make sure you have a good current in your tank.

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.
