How to recognize the longspine cardinalfish ?

The longspine cardinalfish measures between 6 and 8 cm. This fish is bicolore with a predominantly rose body.

Behaviour & Life cycle

  • diet
    carnivorous
  • Sociability
    living as a couple or alone
  • territorial
    Yes
  • Way of living
    nocturnal

The longspine cardinalfish is a fish living as a couple or alone naturally found near the bottom. This species is carnivorous . This fish lives mainly at night. Usually, it leaves its hiding place and starts to be active once it gets dark.

Although slightly territorial, the longspine cardinalfish is a rather peaceful animal that generally behaves in a peaceful manner with other species. It should be noted that it is sometimes less tolerant with its conspecifics. Parades or even small jousts may occur between different members of the group until a hierarchy is established.

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
    25 - 28 °C
  • pH (acidity)
    8.2 - 8.4

  • Robustness

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 longspine cardinalfish

The longspine cardinalfish is a marine species which lives naturally at a temperature between 25 °C and 28 °C. For proper maintenance, the temperature should never exceed the 31°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 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 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 150 liters.

Fearful by nature, it is advised not to let the longspine cardinalfish 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.

As previously said, The longspine cardinalfish 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 longspine cardinalfish 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.
