How to recognize the slender betta ?
Like all fish of its genus, the slender betta has the particularity of being able to breathe in two different ways. In addition to the classic gills, this species is equipped with a breathing apparatus called Labyrinthe which allows it to absorb oxygen from the air. These species are commonly called the labyrinth Fish.
The slender betta measures between 8 and 10 cm.
Sexual dimorphism
The dorsal and anal fins are longer in adult males.

Way of livingdiurnal
The slender betta is a fish that lives in pairs or groups and naturally resides at mid-depth. It is a species with a rather calm temperament.
Although slightly territorial, the slender betta remains a rather peaceful fish that generally behaves in a peaceful manner with other species.
It is worth noting that it is less tolerant towards its congeners without great aggression.

Biotope presentation
The slender betta naturally resides in acidic water.
The acidification of the water comes from the decomposition of plants. This phenomenon alters the water color which tends to darken. In some particularly rich in organic matter areas, the water becomes so stained that it is characterized as blackwater.
The species evolves at shallow depths in areas with a high presence of vegetation (aquatic and marsh plants, decomposing organic matter, branches...).
During dry periods, the slender betta may be found isolated in marshes and small, poorly oxygenated water holes. Its ability to breathe air at the surface allows it to survive until the next season.
The substrate is typically composed of sand and humus.

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.

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 slender betta
The slender betta is a species which lives naturally at a temperature between 27 °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 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 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.
Jumping fish
Be careful, the slender betta is an excellent jumper, naturally using this faculty to change its living area or to escape from predators. The aquarium must be perfectly covered to prevent him from making a deadly jump...
Fish with a maze
The ability to breathe at the surface makes this fish more likely to live in small volumes. Naturally, the slender betta can be found for long periods in water holes where oxygen is scarce.
Cohabitation & Environment
In a community aquarium context, this species should be kept in a minimum volume of 50 liters.
Fearful by nature, it is advised not to let the slender betta cohabit with large territorial species or with too aggressive fish. It can easily evolve with territorial neighbors with a peaceful temperament or with non-territorial species.
Be careful to plan an adequate space for each territorial species. Each species should have a surface and a decor allowing it to juxtapose its territory with that of its neighbors.
The males of this species do not support each other, the maintenance of several of them in the same tank is strongly disadvised.
The slender betta is a fish that generally lives in groups outside of the reproduction periods. If you want to reproduce them and have a good chance of forming a couple, it is recommended to keep at least 5 individuals.. In a community aquarium, the chances of survival of the larvae are almost null. After a few spawns, it is preferable to isolate the couple or to separate from the other members of the group.
The hierarchical organization and the aggressiveness between fellow fish can weaken certain individuals, the presence of hiding places becomes then necessary. If you wish to add new members, it is better to introduce younger fish. They will have a better chance of integrating into the new balance.
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. Floating plants such as Salvinia can be added to recreate the subdued atmosphere characteristic of its living conditions in the wild.
Acid Water Maintenance
The slender betta 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 slender betta is carnivorous.
This species does not appreciate being fed with freeze-dried food (flakes...). Some specimens will never eat this type 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.
