How to recognize Alpheus randalli ?

Alpheus randalli measures between 3 and 5 cm. Given its small size, this species is commonly referred to as a "dwarf" animal. this crustacea is bicolore with a predominantly rouge and blanc body.

Behaviour & Life cycle

  • Sociability
    living as a couple or alone
  • territorial
    Yes
  • Venomous
    No
  • Way of living
    diurnal

Like all crustaceans, Alpheus randalli molts whenever it becomes cramped in its shell. Before the hardening of its new body, it is more vulnerable and spends a good part of its time hidden. This mechanism, very complex, allows the periodic renewal of the exoskeleton and part of the internal skeleton. It is also during the moult that the females become fertile.

Alpheus randalli is a crustacea living as a couple or alone naturally found Dans un terrier. This species is carnivorous . Measuring only a few centimeters, this small species tends to be discreet and hide in the presence of larger neighbors.

Alpheus randalli 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.

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.

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 Alpheus randalli

Alpheus randalli is a marine species which lives naturally at a temperature between 24 °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 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.

Copper is toxic to many invertebrates. Some fertilizers and aquarium foods contain copper sulfate and should be used with caution. Since Alpheus randalli are sensitive to copper, we do not recommend using these products in any form.

Cohabitation & Environment

this crustacea 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 60 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.

Due to their fragile state during moulting, all crustaceans need an environment provided with hiding places (roots, pebbles, leaves, plants, etc.) to shelter in case of danger.

It should be noticed that this species should not be kept with large crustaceans or fish, as it would become a prey of choice. Smaller species should preferably be inserted in the aquarium some time before the larger ones. Moreover, if you want to breed it, it is better to put them in a specific aquarium.

Tips for feeding

Alpheus randalli is omnivorous. This species can be fed with small crustaceans such as mussels, fish or even suitable freeze-dried food.

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.
