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.

Boesemans rainbowfishArea of origin:Boeseman's Rainbowfish inhabits clear, slightly alkaline lakes and tributaries of West Papua. The water is hard, rich in oxygen and often very clear.Species:The Boesemans Rainbowfish belongs to the genus Melanotaenia. Other known species (not identical, but closely related): The species frequently offered in the pet trade include:Melanotaenia boesemani (Boeseman)Melanotaenia praecox (neon rainbowfish)Melanotaenia lacustrisMelanotaenia herbertaxelrodiGlossolepis incisus (red rainbowfish)Social behaviour:Very peaceful Ideal for larger community tanks. Strong mating behaviour, especially in the morning. Show very dynamic swimming behaviour in the shoal. Pair-forming during courtship, but shoaling speciesKeeping conditions:Lots of free swimming space. Dense marginal planting Clear, stable water parameters. Strong filtration and good oxygen supply. A cover is recommended – rainbowfish like to jump. Good light intensity promotes colourfulnessBreedingRelatively simple Free spawners with daily egg-laying over fine-leaved plants or spawning mops. Eggs stick to plants. Parents should be separated after spawning. Fry require the finest powdered food/infusoria, later Artemia nauplii. Hard, slightly alkaline water promotes breeding success.Special featuresOne of the most colourful freshwater fish of all. Colours become more intense with age. Particularly active and keen swimmers. Very social species – keeping them alone leads to stress. Good water quality is crucial for health.Conclusion:Boeseman's rainbowfish are colourful, lively and robust schooling fish that really come into their own in larger aquariums. If you provide sufficient space, clear water and varied feeding, you will have an impressive, active and peaceful aquarium inhabitant.If you have any questions or problems, our trained team at Zoo Roco is here to help.

Area of origin: Malaysia, Borneo and Sumatra; in rivers densely overgrown with plants Social behaviour: Very peaceful, but two males can often fight each other. Keeping conditions: Water level from approx. 30 cm, provide hiding places on the water surface (floating ferns). Do not keep with rowdy fish (e.g. cichlids), T. leeri then loses its magnificent colours and stands shyly in a corner, indeed, does not dare to eat. The room temperature should be above 20-22° C, otherwise the fish will catch a cold easily and become ill Breeding: Lower the water level to approx. 12 cm. A large foam nest is built between aquatic plants and is well guarded by the male after spawning. The male does not drive the female away as brusquely as other labyrinth fish species.Foam nest Special features: Very persistent, the hardiest of the labyrinthine fish next to the blue gourami. Lives for about 8 years. Source: Mergus Atlas Volume 1Our trained team is available to assist you with any questions or issues at Zoo Roco. They can provide you with expert advice 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

ZebrafishArea of origin:The zebrafish originates from clear to slightly murky, shallow streams, rice fields and ponds in South Asia. High oxygen levels and moderate currents are among its natural conditions.Species:The zebrafish is a species within the genus Danio. Other related species:Danio kyathit (leopard danio)Danio choprae (Glowlight Danio)Devario aequipinnatus (giant barbel)The species frequently offered in pet shops includeZebrafish (Danio rerio - wild form)Veiled zebrafishGolden zebrafishLong-finned varietiesLeopard danio (Danio kyathit - often sold as a variant)Social behaviour:Very lively, peaceful schooling fish. Show pronounced group swimming. Play and chase each other playfully. Can become shy if kept too small. Ideal for community tanks with other mobile species.Keeping conditions:They like long, well-filtered aquariums bestLight current desiredOpen swimming zones + planted edge zonesNo strong temperature fluctuationsRobust and adaptable speciesBreeding:Relatively simple. Free spawners. Eggs are released via plants or spawning grids. Parents eat the spawn → separate breeding tanks necessary. The larvae hatch after 2-3 days. Fry need infusoria, later Artemia nauplii.Special features:Very robust and beginner-friendly. Lively and always on the move. Also tolerates cooler temperatures → ideal for unheated aquariums. Important model organism in research (but normal breeding lines in the pet trade)Conclusion:The zebrafish is a lively, uncomplicated schooling fish that enriches any community aquarium with its attractive stripes and socially active behaviour. With sufficient swimming space, good water quality and a larger group, it is particularly lively and harmonious.If you have any questions or problems, our trained team at Zoo Roco is at your disposal.

Herkunftsgebiet: Zaire-Becken von Kinshasa bis Basonga Soziales Verhalten: Friedlich, auch gegenüber Artgenossen. Guter Gesellschafter Hälterungsbedingungen: Ein mit breitblättrigen Pflanzen (Echinodorus) bewachsenes Becken, das mir Wurzeln und Steinen als Unterschlupf ausgestattet sein sollte. Ist das geeignetste Aquarium für diesen Wels. Gern weidet er die Blattunterseite ab, wobei viel eher nach fleischlicher Nahrung (Insektenlaven) als nach Algen gesucht wird. Zucht: Als eine der wenigen Synodontis-Arten wurde S. nigriventris einige Male im Aquarium nachgezüchtet. Die Eier werden in einer Höhle abgelegt. Die Weibchen sind besonders zur Laichzeit sehr rundlich. Die Eltern betreiben eine Art Brutpflege. Die Jungen tragen bis zum 4 Tag einen Dottersack und nehmen bald darauf frischgeschlüpfte Artemia. Ab der 7. Bis 8. Woche drehen sich die Jungen von normaler Schwimmlage auf den Rücken. Bis zu einer Länge von 5 cm (von 2 cm Länge an) bilden die Jungfische gern einen Schwarm. Später verliert sich dieses Verhalten wieder Besonderheiten: Die Rückenschwimmlage ermöglicht es dieser Welsart, besonders die Larven der Stechmücke von der Wasseroberfläche aufzunehmen. Diese Nahrung leitet häufig bei sonst günstigen Bedingungen das Brutgeschäft ein.Quellennachweis: Mergus Atlas Band 1Für Fragen und Probleme steht Ihnen unser ausgebildetes Team im Zoo Roco zur Verfügung.

Herkunftsgebiet: Thailand: Zentralthailand, Menam, Chao Phya-Bassin und die Paknampo--Region. Soziales Verhalten: Einzelgängerisch und revierbildend. Die Tiere sind gegen Artgenossen sehr unverträglich und bissig. Gegenüber anderen Beckeninsassen dagegen meist friedlich. Große Tiere können aber zu wahren Tyrannen werden, die selbst große Mitbewohner terrorisieren. Hälterungsbedingungen: Grosse Recken mit feinem Sand als Bodengrund; Verstecke aus Wurzeln und Steinen. Die Bepflanzung so vornehmen, dass die Tiere Reviere bilden können, ohne direkten Sichtkontakt mit ihren Nachbarn zu haben. Viel freier Schwimmraum. Weiches bis mittelhartes (bis 15 dGH) und neutrales Wasser (pH um 7). Die Art ist nur bedingt für das Gesellschaftsbecken geeignet. Zucht: Die Zucht ist wegen der Unverträglichkeit der Tiere sehr schwierig und deshalb nur selten gelungen.Über die gelungene Zucht von E. bicolor berichten DEAKIN & MORRILL. Zuchttemperatur 27 - 28 Grad C; Wasser weich und mit Torf angesäuert. Es wurde in einer Steinhöhle abgelaicht. Die Jungfische schlüpften nach zwei Tagen und nach weiteren zwei Tagen schwammen sie frei. Die Jungfische haben weiße Flossenspitzen. Ihre Färbung geht von einem silbrigen Braun über Dunkelbraun zu Schwarz über. Die Schwanzflosse und wird erst ab der 7. Woche rötlich.Quellennachweis: Mergus Atlas Band 1Für Fragen und Probleme steht Ihnen unser ausgebildetes Team im Zoo Roco zur Verfügung. Es kann Sie in allen Fragen fachgerecht beraten.
