How to recognize Petrochromis ephippium ?

Petrochromis ephippium measures around 18 cm. The dominant males can however reach 20 cm.

Behaviour & Life cycle

    herbivorous
  • Sociability
    living in small groups
  • territorial
    Yes
  • Way of living
    diurnal

Petrochromis ephippium is a fish living in small groups naturally found near the bottom. The members of each group are organized around a well established hierarchy. This species is herbivorous . Naturally, it tends to dig into the sand and transform its environment.

Petrochromis ephippium 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. In a constant quest for dominance, the dominant males of this species cannot stand each other. The battle between two individuals can be intense and violent. It will result in the submission and sometimes even death of one of the protagonists.

Reproduction

  • Polygamy
    Yes

Petrochromis ephippium is a fish ovipare incubateur buccal. In this species, the dominant males are polygamous and reproduce each season with several females.

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
    1500 liters
  • Population min
    3
  • Temperature
    23 - 28 °C
  • pH (acidity)
    8.2 - 8.4

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 Petrochromis ephippium

Petrochromis ephippium is a marine species which lives naturally at a temperature between 23 °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.

Petrochromis ephippium 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.

Builder fish

This fish has the particularity to dig its territory in the sand. Therefore, it is likely to uproot plants and modify the decor of the aquarium.

Formal incompatibilities

Be careful, Petrochromis ephippium is incompatible with plants.

Cohabitation & Environment

Petrochromis ephippium is a fish which it is advisable to maintain in specific aquarium. Associating it with other species is not fundamentally impossible but a documentation work is necessary for the constitution of the population. Being a living in small groups fish, it is advisable to install at least 3 individuals in an aquarium of 1500 liters minimum (for 200 cm of frontage). Group maintenance is a prerequisite to ensure their well-being. Lonely individuals tend to quickly become stressed and become especially susceptible to disease.

The males of this species do not support each other, the maintenance of several of them in the same tank is strongly disadvised.

This fish being polygamous, the male must always be maintained with several females. A ratio of three females to one male seems to be a good compromise for the constitution of the group.

To best reproduce the biotope of this species, you can cover the bottom of the tank with sand and put a pile of stones to form caves.

Be careful, this species does not appreciate plants and will end up destroying, uprooting or nibbling them. It will not be possible to make an aquarium planted in its presence.

Tips for feeding

Petrochromis ephippium is herbivorous.

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

  • Maintenance difficulty
    moderate
  • egg-laying protection
    Yes

Reproduction of this species in an aquarium is considered moderate. Ideally, it takes place at a temperature of around 25 ° C for a pH of 8 .

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.
