How to recognize the goldtail demoiselle ?
This damselfish is bi-colored with a predominantly blue pattern. It gets its common name from the golden yellow color of its caudal fin.
Sexual dimorphism
The adult male is larger than the female.
Behaviour & Life cycle
-
dietomnivorous
-
Sociabilityliving as a couple or alone
-
territorialYes
-
Way of livingdiurnal
The goldtail damselfish lives in small groups among the branches of Acropora corals. It spends its entire life cycle in these coral habitats, which provide effective shelter from predators.
As territorial fish, they protect their living area from species with similar habits, especially other damselfish and clownfish.

Hermaphroditeprotogynous
Chrysiptera parasema is an oviparous fish that spawns on exposed substrate. The eggs adhere to the substrate and are guarded by the males until hatching.

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.
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 goldtail demoiselle
The goldtail demoiselle is a marine species which lives naturally at a temperature between 22 °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. In seawater, it is also possible to remove nitrates using one of the following methods: Jaubert, denitrator on sulfur, biopeletts, vodka method.
Breeding this species is accessible to any hobbyist. It is recommended to follow some basic rules and to be rigorous to achieve a good maintenance.
Cohabitation & Environment
In a community aquarium context, this species should be kept in a minimum volume of 200 liters.
The goldtail 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.
The males of this species do not support each other, the maintenance of several of them in the same tank is strongly disadvised.
As previously said, The goldtail demoiselle 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
The goldtail demoiselle is omnivorous.
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.
