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.

Periophthalmus novemradiatus - The Indian mudskipperOrigin & habitatThe Indian mudskipper (Periophthalmus novemradiatus) originates from the coastal regions of South Asia, particularly India, Sri Lanka and Bangladesh. Its favourite habitat is mangrove forests, brackish water zones, muddy estuaries and intertidal zones. Here it finds ideal conditions to live between water and land.AppearanceThis unusual fish has an elongated, scale-covered body, which is usually grey-brownish in colour and can be covered with small, shimmering spots. Particularly striking are its protruding eyes, which sit high up on the head and can be moved independently of each other - a perfect adaptation to life outside the water. Males also have a more conspicuous dorsal fin, which they raise for courtship.SizePeriophthalmus novemradiatus is one of the smaller mudskipper species. Adults reach a length of around 6 to 10 centimetres.Life expectancyIn suitable husbandry or under natural conditions, an Indian mudskipper can live for around 3 to 5 years. Factors such as water quality, diet and habitat play an important role here.LifestyleThe Indian mudskipper is diurnal and semi-aquatic, which means that it spends most of its time out of the water. Thanks to its powerful pectoral fins, it can "jump" and move on wet mud. It uses both its gills and a special skin respiration system to breathe as long as the skin remains moist. Mudskippers are territorial and can be quite aggressive towards conspecifics.Unique characteristicsAmphibious lifestyle: One of the few fish that can actively move around on land.Eyes like a chameleon: Their eyes can rotate independently of one another – a great advantage for navigation and hunting prey.Jumping & Climbing: Despite their small size, they can jump surprisingly far and even climb roots or stones.Skin and mucous membrane respiration: Like amphibians, the mudskipper can also absorb oxygen through its moist skin and the mucous membranes in its mouth and throat. However, this epidermal respiration only works as long as the skin is well moistened – which is why the mudskipper relies on a humid environment or frequent periods in the water.Keeping in a paludariumA paludarium - a combination of aquarium and terrarium - is ideal for keeping the Indian mudskipper in a species-appropriate way. This should offer both a water area and sufficient land area with a moist, muddy or sandy substrate.SetupLand area: At least half of the paludarium should consist of dry, slightly damp sand on which the animals can walk and jump. Fine aquarium sand or a clay-sand mixture works well.Aquarium section: Shallow and warm (24–28°C), with slightly brackish water (salinity approx. 5–15 g/L), as the animals originate from brackish water zones.Hiding places & climbing opportunities: Roots, stones or mangrove roots provide shelter and climbing opportunities.Plants: Saltwater-tolerant plants or artificial alternatives can be used – a robust setup is important, as the fish dig.TidesA particularly natural paludarium offers a simulated ebb and flow of the tide. This can be controlled using pumps or a timer: At high tide, the water area fills slowly and provides access for swimming. At low tide, the water level drops and more land becomes accessible. This corresponds to the natural behaviour of the animals and significantly stimulates their activity.General conditionsLighting: Daylight simulation with UV components is recommended.Humidity: High, ideally between 70–90%.Cover: The paludarium should be well covered, as mudskippers are excellent climbers and can escape quickly.Created with ChatGPT – revised by Zoo Roco

The Siamese fighting fish (Betta splendens) Area of origin: The Siamese fighting fish is a world-famous aquarium inhabitant, originally from Thailand, or more precisely from Southeast Asia. Habitat: Fighting fish live in small warm puddles, ponds, lakes, in rice fields as well as floodplains and lagoons.The fighting fish use the dense vegetation to protect themselves from predators. Care: The fighting fish aquarium has a volume of 20 to 25 litres and therefore falls into the category of nano aquariums.When choosing a tank, you should also make sure that the height does not exceed 40 cm, as the fighting fish does not have the strength to swim very high to get air.As fighting fish are very calm and slow animals, it is not advisable to install a strong-flowing pump. Fighting fish need little to no current. Some of today's cultivated forms have fins so large that the fighting fish cannot swim for long at a time as they quickly become exhausted.The male fighting fish must be kept individually, as the name suggests: they fight, and that to the death. The females, on the other hand, can be kept in groups. Breeding fighting fish, in turn, is more difficult, as even there quarrels can occur.Fighting fish should be fed as variedly as possible. It is advisable to offer live and frozen food from time to time, such as mosquito larvae, water fleas and artemia. They occupy a territory, which they regularly swim around. If the territory is too large, a fighting fish does not feel comfortable as it quickly loses track. It is not advisable to keep them with other fish, as fighting fish feel stressed or receive too little food. They are best kept with snails. Fighting fish like tanks that are heavily planted, as this offers hiding places and the fighting fish can also rest among the plants. It is important that not the whole water surface is covered with plants, as the fighting fish is a labyrinth fish and breathes air at the water surface. Food: The fighting fish are pure carnivores. Ornamental fish food with plant-based ingredients can make the fighting fish ill, so a flake food consisting only of meat is highly recommended. When feeding the fighting fish, the following applies: regularly, but in small quantities.

Profile angelfishArea of origin:Angelfish originate from the tropical Amazon basin in Brazil, Peru and Colombia. They live in stagnant or slow-flowing waters with dense vegetation and root structures.Species:The genus Pterophyllum includes:Pterophyllum scalare (common angelfish, often found in the trade)Pterophyllum altum (Altum angelfish – more demanding, significantly larger)Pterophyllum leopoldi (smallest species)The species frequently offered in pet shops include: (breeding and colour forms)Silver angelfish (wild form)Marbled angelfish Koi angelfishVeiled angelfish  Black angelfish  Gold angelfish  Zebra angelfish  Platinum angelfish Social behaviour:Angelfish are social and form hierarchies within the group. They are peaceful towards calm species, but can eat smaller fish (neons, guppies). With increasing pair formation, angelfish defend breeding territories vigorously.Keeping conditions:High aquariums with plants, roots and quiet corners.  Free space for swimming required.  Very good water quality, regular water changes.  Not too strong a current Ideal companionship with larger characins, catfish, calm barbsBreeding:Angelfish form monogamous pairs Spawn on broad leaves, roots or vertical surfaces.  Parents provide brood care: fanning the eggs and guarding the young.  For successful breeding: calm species tank, stable water values, slightly acidic waterSpecial features:Impressive body height and elegant swimming style.  Sensitive to stress and poor water quality.  Particularly beautiful colour variants available.  Become tame and show individual behaviour.Conclusion:The angelfish is a majestic, peaceful cichlid that reveals its full beauty in tall, well-structured aquariums.

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

Profile Black Phantom TetraArea of origin:The black phantom tetra lives in slow-flowing, densely vegetated waters in South America. The water is often soft, slightly acidic and shady due to plant growth.Species:The black phantom tetra offered in the trade is predominantly Hyphessobrycon megalopterus.Other "phantom" species are e.g:Red phantom tetra (Hyphessobrycon sweglesi)White phantom tetra (Megalamphodus megalopterus var.)The species frequently offered in pet shops includeBlack phantom tetra (standard form)Rarer:Longfin variantSocial behaviour:The black phantom tetra is peaceful and displays beautiful courtship and display behaviour within the school - the males in particular show off their large dorsal fins. It is ideal for community aquariums with other calm species.Keeping conditions:Well-planted aquarium with free swimming zones. Darkened areas (roots, floating plants) preferred. Gentle current. Stable water values and regular water changes. Dark substrate makes the colours appear stronger.Breeding:Free spawners - the eggs are scattered over plants or spawning substrates. Parents eat the spawn → breeding tank necessary. Soft, slightly acidic water promotes spawning success. Fry are very small and require infusoria/small food.Special features:Very peaceful and ideal for community tanks Males like to show off with fanned-out fins Colours look particularly intense in shady, darker aquariums Robust and well suited for beginners Conclusion:The black phantom tetra is an elegant, peaceful schooling fish that particularly comes into its own in well-planted aquariums with soft light. Its harmonious nature and beautiful contrasting colours make it an ideal inhabitant for many community aquariums.If you have any questions or problems, our trained team at Zoo Roco is here to help.

Herkunftsgebiet: Neuguinea: Küstenebene und anschliessendes inneres Tiefland zwischen Dyke Ackland Bay und Collingwood Bay an dem östlichen Ende von Neuguinea. Soziales Verhalten: Munterer, friedlicher Schwarmfisch Hälterungsbedingungen: Wie bei P. connieae angegeben. P. furcatus liebt dichte Bepflanzung der Becken. Zucht: Ähnelt stark der von P. connieae. Einzelheiten:ALLEN & CROSS (1982): Rainbowfishes of Australia and Papua New Guinea, T.F.H.-Verlag, beschreiben ein Zuchtbecken für die Pseudomugil-Arten folgendermassen: Ein Becken mit den Massen 40 x 25 x 25 cm reicht aus. Der Boden sollte mit einer dünnen Sandschicht bedeckt sein, einen Klumpen Javamoos und 2 oder 3 schwimmende Riccia-Polster sowie einen schwach arbeitenden Ausströmerstein enthalten. Man kann die Tiere sowohl paarweise als auch in Gruppen zur Zucht ansetzen. Ist das Männchen zu aggressiv, so gibt man 1 - 2 weitere Weibchen hinzu. Ein Ansatz im Schwarm bringt erheblich bessere Ergebnisse als paarweise Zucht. Die Tiere laichen gewöhnlich am Morgen ab. Die Eier haben Haftfäden und kleben an den Wasserpflanzen. Die Entwicklungszeit beträgt bei 25° C 15 - 20 Tage. Die Elterntiere werden herausgefangen (Laichräuber). Fütterung der Jungen mit Infusorien und Staubfutter. Besonderheiten: P. furcatus unterscheidet sich von P. connieae durch das Vorhandensein von gewöhnlich 8 - 9 (selten 7) segmentierten Strahlen in der zweiten Rücken-flosse (10 - 11, gelegentlich 9, selten 12 bei P. connieae) und durch je einen dorsalen und ventralen Rand in der Schwanzflosse. d von P. furcatus haben eine kräftig orangefarbene Brust, während sie bei P. connieae gelb ist.Quellennachweis: Mergus Atlas Band 2Für Fragen und Probleme steht Ihnen unser ausgebildetes Team im Zoo Roco zur Verfügung.

Zebra catfish profileArea of origin:The zebra catfish originates exclusively from the Rio Xingu in Brazil - a warm, clear, fast-flowing river with lots of rocks and crevices. It lives in current areas between rocks and requires appropriate conditions in the aquarium.Species:Hypancistrus zebra is a separate species. Other similar Hypancistrus species: Hypancistrus sp. L066 (King Tiger) Hypancistrus sp. L333 Hypancistrus sp. L260 (Queen Arabesque) The true L046 is, however, the rarest and most sought-after species.The species frequently offered in pet shops includeHypancistrus zebra (L046) - mostly captive bredHypancistrus sp. L260Hypancistrus sp. L333Hypancistrus sp. L066Social behaviour:The zebra catfish is quiet, peaceful and likes to hide. It is nocturnal, but comes out regularly when conditions are calm. Territorial behaviour is particularly pronounced among males during breeding.Keeping conditions:Warm, oxygen-rich water. Strong current desirable. Many stone structures, narrow passages, tubes. Very clean water - sensitive to nitrite/nitrate. Subdued light, shadow zones. Only socialise with calm species (ideally species tanks)Breeding:Breeding in the aquarium is possible and often the only way to preserve the species. Cave breeders Male guards clutch until hatching. Young initially eat fine frozen and live food. Very soft, acidic water promotes breeding success. Patience required - breeding takes a long time.Special features:Very rare and protected in the wild. Often expensive due to the difficult origin and strict export regulations. Absolute warm water species. Very sensitive to poor water quality. Ideal for advanced aquarists. Beautiful black and white markings - unmistakable!Conclusion:The zebra catfish is an impressive, highly rare aquarium fish with unique markings and unusual behaviour. It requires warm, very clean water, lots of caves and a quiet environment. For experienced aquarists, it is a real treasure that can even be successfully bred with the right care.If you have any questions or problems, our trained team at Zoo Roco is here to help.
