Boesemans rainbowfish

Fairy shrimps (spring gillfoot) Fairy shrimps (spring gillfoot) are very common. Fairy shrimps are gilled crustaceans that have been found on our planet since prehistoric times in salt lakes, drying waters or polar waters.Only animals from Asia or America that live in a water temperature of 20-30°C are suitable for keeping in an aquarium. These species (Branchinella thailandensis and Dendrocephalus brasiliensis) live in waters that regularly dry out and are only filled with rainwater. The water is therefore very soft. Appearance The animals have 11 pairs of leaf feet. These leaf-shaped limbs serve not only for locomotion but also for breathing – which has led to the term "gilled-foot crustacean". There are sometimes minor differences in colour. They are found in colours ranging from orange to reddish-brown and may have greenish to bluish hues at the joints and at the boundaries of the segments.Both sexes have two short thread-like antennae. However, another pair of antennae differ in both shape and according to sex. Males have lobe-shaped appendages that can be curled up. Adult females are mainly distinguished by the ventrally located brood sacs, which are filled with eggs, and the ends of the female's tail are translucently light. Systematics Phylum: Arthropoda / ArthropodsSubphylum: Crustacea / CrustaceansClass: Anostraca – Gill-feetFamily: BranchipodidaeGenus: Branchipus / Eubranchipus /Tanymastix etc. Care Depending on the species, fairy shrimps live for 6-12 weeks and the size of adult animals varies from 1-3cm.Can Triops and fairy shrimps be kept together?yes, they can Aquarium size: Initially, a Faunarium box size 230 x 155 x 170 mm is quite sufficient From a body length of 1.5cm, they can be gradually accustomed to larger tanks Basic lighting: Sunlight or aquarium lighting is sufficientAeration: An air pump with a stone and very little air flow is sufficient for keepingSetup:Only water and breeding substrate in the breeding/starting container. A little fine aquarium sand can be used as substrate (but this is not absolutely necessary)Decorations can be used, but are only for our eyes and not of importance to the fairy shrimps.Fairy shrimps are free-swimmers – so they need enough free swimming space in the breeding container.If the animals swim around freely, you can also add a little aquarium moss to the water. To ensure the water is soft, it is best to use 2/3 distilled water and 1/3 mineral water (non-carbonated).Water temperature: Fluctuations in temperature of +/- 5° C are not dramatic.The ideal breeding temperature is 26°.Start:The larvae only hatch when they are completely surrounded by water. Therefore, place the eggs on adhesive tape and then put this in the water – so the eggs are not washed to the edge and always remain in contact with water.After 1-3 days the larvae hatch. The larvae grow quickly and can reach sexual maturity after up to 40 moults in one to two weeks. The males hold the females with their jaw pincers shortly before and also during mating. After mating, the eggs develop in the egg sacs on the females’ abdomens. They fall to the bottom of the water and can survive for several years of prolonged drought in the substrate.When the fairy shrimps have died, the water can be drained off and the substrate with the eggs left completely dry. The larvae can only hatch again if the eggs were completely dry.Once this is dried out, a new batch can be started.If no substrate is used, you can also siphon off the eggs with a thin hose. Let the water containing the eggs run through a fine net or a coffee filter – this way you can collect the eggs.Important: The animals do not tolerate large water changes. If fairy shrimps are to be moved to a larger home, it is best to place the animals together with the breeding water into the new home or tank and slowly fill up the container with conditioned tap water. Feeding The larvae are fed from the 3rd day after hatching.The larvae can be fed with algae powder or JBL Artemio fluid. For all animal husbandry: Children must be guided, supervised and monitored by their parents. Children must learn that an animal has its own needs and habits and they must respect this. Parents should be aware that they are responsible for the animal. For questions and problems our trained team at Zoo Roco is at your disposal. They can advise you professionally on all matters.

A journey of discovery into the world of the axolotlIn the mysterious and fascinating world of aquatic creatures, there is one creature that delights scientists and enthusiasts alike: the axolotl. With its fascinating appearance and amazing abilities, this amphibious salamander has captured the hearts of many people and is increasingly becoming the object of research and admiration. Let's immerse ourselves in the world of the axolotl and discover what makes these fascinating creatures so special.Origin: Originally native to the waters around Lake Xochimilco in Mexico.Life expectancy: In the wild, axolotls can live for around 10-15 years, while in human care they can often live up to 15-20 years or even longer.Appearance: The axolotl is an amphibious tailed amphibian and often retains juvenile characteristics even when fully grown. It has a flat body, external gills that look like a curly crest, and characteristic small eyes. Colours vary depending on the breeding line and range from white to grey, brown and black.Size: Axolotls typically reach a length of around 15-45 centimetres, with females usually being larger than males.Lifestyle: Axolotls are aquatic creatures and spend their entire lives in water. They are nocturnal and feed mainly on small fish, insects, worms and other invertebrates.Origin and habitatThe axolotl (Ambystoma mexicanum) is a tailed salamander that is originally native to the waters around Lake Xochimilco in Mexico. This species of salamander is found exclusively in a small area in central Mexico, making it an endemic species. Historically, the axolotl was an important part of Aztec culture and mythology, which further emphasises its importance in the region.Unique characteristicsWhat makes the axolotl particularly fascinating are its amazing regenerative abilities. Unlike most other amphibians, the axolotl retains its ability to regenerate limbs, organs and even parts of its brain well into adulthood. This remarkable property has piqued the interest of medical researchers as it could potentially provide insights to regenerate human tissues as well.The axolotl is also known for its neotenic appearance, which means that it retains certain juvenile characteristics even when fully grown. These include its extremely cute facial expression, external gills and, of course, its characteristic swan neck. These characteristics make the axolotl a popular pet and a sought-after species in aquariums worldwide.Threatened existenceDespite its fascinating characteristics and popularity as a pet, the axolotl unfortunately faces serious threats in the wild. The destruction of its natural habitat through pollution, drainage of wetlands and the introduction of non-native species have led to a sharp decline in populations. In the wild, the axolotl is even considered endangered and its future is uncertain.The importance of protectionWith the axolotl under increasing threat, it is vital that measures are taken to protect its habitats and conserve its populations. This requires not only protecting the waters in which the axolotl lives, but also raising public awareness of the importance of conserving this fascinating species. Furthermore, it is important to continue research on the axolotl in order to better understand its regenerative potential and possibly transfer it to medical applications.Overall, the axolotl is undoubtedly a remarkable creature, admired not only for its cute appearance, but also for its unique abilities and its importance to science. It is up to us to safeguard its future and ensure that this fascinating creature continues to enrich the waters of our planet for a long time to come.Created with ChatGPT – revised by Zoo Roco
