How to recognize the green pufferfish ?

This species belongs to the group of pufferfish. These fish are nicknamed like this because they have the ability to inflate themselves when they feel threatened.

To achieve this inflation, they swallow water and fill their stomach to more than double their volume. This is made possible by their stretchy skin. This subterfuge makes them look much more impressive to their predators. They are also much more complicated to swallow. This change in shape becomes a disadvantage for these fish that, once inflated, can hardly move.

The green pufferfish measures between 15 and 17 cm. This fish is tricolore with a predominantly jaune, noir and blanc body. The also has noir tasks.

Behaviour & Life cycle

  • diet
    carnivorous
  • Sociability
    living in small groups
  • territorial
    No
  • Way of living
    diurnal

The green pufferfish is a fish living in small groups naturally found at mid-depth and near the bottom. This species is carnivorous .

Although the green pufferfish is non-territorial, it is sometimes aggressive towards other species. It also shows signs of aggression towards its conspecifics.

Reproduction

  • Reproduction
    ovipare qui pond sur substrat découvert

The green pufferfish is a fish ovipare qui pond sur substrat découvert. This fish protects its eggs from nearby predators.

Risks for humans

  • Venomous
    No
  • Bite
    Yes

This species can attack if it feels threatened. It is important to be particularly vigilant especially during dives or fishing sessions.

Biotope presentation

The green pufferfish is most often found at a depth between 0m and 2m. However, it is not impossible to find this species at other depths. This animal evolves in areas characterized by a strong presence of vegetation (aquatic and marsh plants, decaying organic matter, roots...).

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
    150 liters
  • Population min

  • Temperature
    24 - 29 °C
  • pH (acidity)
    7.8 - 8.4

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 green pufferfish

The green pufferfish is a species which lives naturally at a temperature between 24 °C and 29 °C. For proper maintenance, the temperature should never exceed the 32°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 green pufferfish 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 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.

Formal incompatibilities

Be careful, the green pufferfish is incompatible with molluscs and crustacean.

Cohabitation & Environment

Being a living in small groups fish, it is advisable to install at least 0 individuals in an aquarium of 150 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. Warning, mixing several species living in the same living area is not recommended if the volume is not significant. This fish being a predatory species, it is recommended to maintain it in a specific environment, without other species. Indeed, any crustacean or fish of lower size will become a potential prey. If you still try to associate it with other species, the cohabitants must be of a size at least comparable to the predator in a much larger volume. The aquarium can be provided with many hiding places and a large space to allow each individual to find refuge if necessary.

The species enjoys a particularly vegetation-rich environment. The addition of plants will provide many useful hiding places for resting. These areas are also conducive to possible breeding in the aquarium.

Basic water maintenance

The green pufferfish 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

The green pufferfish 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.
