How to recognize the rolland's demoiselle ?

The rolland's demoiselle measures around 5 cm. The dominant males can however reach 7.5 cm. This fish is tricolore with a predominantly jaune, noir and blanc body.

Sexual dimorphism

The adult male is bigger than the female.

Behaviour & Life cycle

  • diet
    carnivorous
  • Sociability
    living in a group or alone
  • territorial
    Yes
  • Way of living
    diurnal

The rolland's demoiselle is a fish living in a group or alone naturally found near the bottom. This species is carnivorous .

The rolland's demoiselle is a territorial animal that does not tolerate any incursions into its living area. It is particularly virulent against other territorial species and it can provoke heated fights. Relationships between conspecifics are also hectic, with each seeking to secure its place.

Reproduction

  • Reproduction
    ovipare qui pond sur substrat découvert
  • Hermaphrodite
    protogynous

The rolland's demoiselle is a fish ovipare qui pond sur substrat découvert. always born female. Growing up, individuals will change sex to become male, this is called successive hermaphroditism of the protogynous type. This fish protects its eggs from nearby predators.

Harmless species

This species does not represent any particular threats to humans when encountered in its natural environment.

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
    60 liters
  • Population min
    1
  • Temperature
    26 - 29 °C

Characteristics

  • Difficulty breeding
    hard
  • Robustness
    tolerant
  • Behaviour
    moderately 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.

The realization of a seawater aquarium requires certain knowledge beforehand. Seawater is generally synthetic, consisting of reverse osmosis water and synthetic salt at a level of 33g / liters. It is also possible to take seawater directly (after making sure that the water is not polluted). The operation of a seawater aquarium is done in three phases: the installation of a living stone decoration, the introduction of invertebrates one month later, and the introduction of fish 3 months later. It is essential to wait as long as possible before to introduce the animals so that the micro-fauna has had time to develop well. The balance and the physico-chemical stability are fundamental for the success of this type of tank.

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 rolland's demoiselle

The rolland's demoiselle is a marine species which lives naturally at a temperature between 26 °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. In seawater, it is also possible to remove nitrates using one of the following methods: Jaubert, denitrator on sulfur, biopeletts, vodka method.

The rolland's demoiselle 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.

Cohabitation & Environment

In a community aquarium context, this species should be kept in a minimum volume of 60 liters.

The rolland's demoiselle has a strong character. Its maintenance with territorial neighbors in an inadequate volume will generate stress. ndeed, it will not hesitate to fight to protect its territory and to dominate its neighbors. It is important to think carefully about the constitution of the future population to avoid this kind of inconvenience. The aquarium should be arranged so that each species can comfortably define its own territory.

Tips for feeding

The rolland's demoiselle 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.

Reproduction protocol

  • Spawning cleaning
    Female & Male
  • egg-laying protection
    Female & Male
  • Fry protection

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.
