How to recognize the twospot turkeyfish ?

The twospot turkeyfish is tricolored with a predominantly red-orange, brown, and white pattern. Its design vaguely resembles vertical stripes.

Its dorsal fin is composed of 13 more or less long spines striped in beige and brown. Part of this fin is white, punctuated with two characteristic black spots (ocelli).

Behaviour & Life cycle

  • diet
    carnivorous
  • Sociability
    solitary
  • territorial
    No
  • Way of living
    nocturnal

The twospot turkeyfish is generally encountered solitary. Nocturnal fish, it remains hidden in caves and sponges for most of the day. Once night falls, it goes hunting alone for small fish or crustaceans.

Although this fish is not territorially aggressive, it can sometimes show aggressiveness towards other species.

Reproduction

The twospot turkeyfish is an oviparous fish that spawns in open water.

Risks for humans

  • Venomous
    Yes

This species is venomous and can cause serious injuries when touched.

Biotope presentation

The twospot turkeyfish is most commonly found at a depth of less than 40 meters. However, it is not impossible to find this fish at other depths.

It is shy and rarely seen. It frequents clear waters rich in corals.

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
    300 liters
  • Population min
    1
  • Temperature
    22 - 26 °C
  • pH (acidity)
    8.2 - 8.4

Characteristics

  • Difficulty breeding
    moderate
  • Robustness
    robust
  • Behaviour
    slightly 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.

Beware, as this species is potentially dangerous to humans, it requires for its maintenance the obtaining of a "certificate of capacity of breeding". For professionals, it is necessary to have a "certificate of presentation to the public".

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 twospot turkeyfish

The twospot turkeyfish 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.

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.

Formal incompatibilities

Be careful, the twospot turkeyfish is incompatible with crustacean.

Cohabitation & Environment

This fish being a predatory species, it is recommended to maintain it in a specific environment, without other species. Indeed, any crustacean or fish of lower size will become a potential prey. A 300 liter aquarium is the minimum recommended for its maintenance. If you still try to associate it with other species, the cohabitants must be of a size at least comparable to the predator in a much larger volume. The aquarium can be provided with many hiding places and a large space to allow each individual to find refuge if necessary.

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.

Tips for feeding

The twospot turkeyfish 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.

  • egg-laying protection
    No

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.
