Product information "Prehistoric Cancer Eggs"

Primeval crabs


Observing primeval crayfish from the egg stage to the adult animals - a real experience at home.
Primeval crayfish are suitable for both beginners and experienced aquarists, as they are easy to keep and breed. They will delight young and old. Each pack of primeval crayfish eggs comes with detailed instructions.

Available in three forms:

Triops longicaudatus
is an American shield crayfish, which has a light olive-green marbling at the beginning. With age the marbling disappears and the colours become more intense.
Size: max. 9 cm
Temperature: 21 - 26 °C
Life expectancy: max. 3 months
Food: primeval crayfish food

Triops longicaudatus (red)
is an American crayfish. This species is probably a breeding form of the "normal" Triops longicaudatus. In contrast to these, however, the body shell of Triops longicaudatus (red) is transparent, which is why the animals appear wonderfully red in colour due to the translucent red blood.
Quantity: basically about 100 to 250 eggs
Size: max. 9 cm
Temperature: 21 - 26 °C
Life expectancy: max. 3 months

Triops cancriformis var. Beni Kabuto Ebi (red)
The red cultivated form of the European summer crab Triops cancriformis probably comes from Asia and has therefore been given the name "Beni Kabuto Ebi". Keeping and breeding corresponds to the original species.
The original form is brown marbled. The red Triops lack the brown colour, which is why they appear red due to their body fluid. However, if you look closely, you can still see the marbling. As juveniles, like all Triops species, they are still quite pale. The strong pinkish-red colour develops only with age.
Size: max. 7 cm
Temperature: 20 - 25 °C
Life expectancy: max. 3 months

JBL PRONOVO SPIRULINA GRANO S 100ml
JBL Pronovo Spirulina Grano SSpirulina, green food granulate for all small herbivores from 3 to 10 cmSinking, prebiotic Spirulina algae food granulate for herbivorous (plant/algae-eating) aquarium inhabitants such as livebearers and shrimpsNatural raw materials without artificial additives for a natural diet and healthy aquarium fish and invertebrates. Tested on JBL research expeditions in the tropicsVery high acceptance even by fussy fish & shrimp species due to high-quality raw materials such as spirulina and shrimpsVery high spirulina algae content of 20 % for healthy fish and optimum colour formationScope of delivery: original sealed, airtight and light-proof, recyclable tin with click-doser as feeding aidSpirulina are blue-green algae, some species of which, such as the S. platensis processed here, have ideal protein contents for feeding ornamental fish. Incidentally, the spirulina content of 20 % in JBL PRONOVO SPIRULINA food is optimal - more would not be healthy for the fish! The natural astaxanthin (a carotene) in the algae causes the beautiful colouring of the fish. This is another reason why spirulina algae are very popular for feeding ornamental fish.Probiotic or prebiotic - which is better?Probiotic foods, such as some types of yoghurt, contain live bacterial cultures to promote health, but only if consumed in larger quantities. Such foods, including probiotic fish food, can easily spoil and then have the opposite effect. The positive effect on health is, by the way, quite controversial.Pre- or prebiotics are "substrates that are selectively used by host microorganisms and impart health benefits." Here, scientists agree that they promote digestion and thus health. In the case of our fish, there is another essential aspect: With better digestion, less is excreted and thus the water is less polluted, which keeps the water cleaner and results in fewer algae problems.Flakes or granules?Honestly: It is a kind of question of faith! There are few arguments for or against the type of food. If you use an automatic feeder such as the JBL AutoFood, you MUST choose granulate food, as almost all automatic feeders are only suitable for granulates. If an automatic feeder is due on your next holiday, get your fish used to the granules from the feeder RIGHT NOW. Some fish actually find it a little difficult to switch from granules to flakes or vice versa. Imagine that you have always eaten soft cornflakes and are now getting wholemeal cereal for the first time.

Eubranchipus grubii
Feenkrebse (Frühjahrskiemenfuss) Feenkrebse (Frühjahrskiemenfuss) sind sehr verbreitet. Feenkrebse sind Kiemenfüsser, die seit Urzeit auf unserem Planeten in Salzseen, Austrocknungsgewässern oder Polargewässern zu finden sind.Für die Haltung im Aquarium eignen sich nur die Tiere aus Asien oder Amerika, die in einer Wassertemperatur von 20-30°C leben. Diese Arten (Branchinella thailandensis und Dendrocephalus brasiliensis) leben in Gewässern, die regelmässig wieder austrocknen und nur von Regenwasser gefüllt werden. Deshalb ist das Wasser auch sehr weich. Aussehen Die Tiere besitzen 11 Paare von Blattfüssen. Diese blattförmigen Gliedmassen dienen nicht nur der Fortbewegung, sondern auch der Atmung - was zu der Bezeichnung „Kiemenfusskrebs“ geführt hat. Farblich gibt es teils kleinere Unterschiede. Farblich anzutreffen sind diese orange bis rötlich-braun und können grünliche bis blaue Färbungen an den Gelenken und an den Grenzen der Segmente aufweisen.Beide Geschlechter verfügen über zwei kurze fadenförmige Antennen. Ein weiteres Paar Antennen unterscheiden sich jedoch von der Form und dem Geschlecht. Bei den Männchen tragen sie lappenförmige Anhänge, die eingerollt werden können. Erwachsene Weibchen erkennt man vor allem auch an den bauchseitig gelegenen Brutsäcken, die mit Eiern gefüllt sind und das Schwanzende der Weibchen sind durchscheinend hell. Systematik Stamm: Arthropoda / GliederfüsserUnterstamm: Crustacea / KrebstiereKlasse: Anostraca – KiemenfüßeFamilie: BranchipodidaeGattung: Branchipus / Eubranchipus /Tanymastix etc. Haltung Je nach Art werden die Feenkrebse 6-12 Wochen alt und die Grösse der ausgewachsenen Tiere variiert von 1-3cm.Kann man Triops und Feenkrebse zusammen halten?ja das geht Aquariumgrösse: Anfangs reicht eine Faunarium Box Grösse 230 x 155 x 170 mm durchaus Ab einer Tierlänge von 1.5cm kann man sie langsam an grössere Becken gewöhnen Grundbeleuchtung: Sonnenlicht oder eine Aquarienbeleuchtung reicht ausBelüftung: Eine Luftpumpe mit einem Stein und ganz wenig Luftdurchlass genügt für die HaltungEinrichtung:Nur Wasser und Zuchtansatz in den Anzucht-/Anfangsbehälter. Als Bodengrund kann man ein wenig feinen Aquariumsand benutzen (ist aber nicht unbedingt notwendig)Dekrationen können benutzt werden, sind aber nur für unser Auge und nicht für die Feenkrebse von Bedeutung.Feenkrebse sind Freischwimmer – brauchen also genügend freien Schwimmraum im Zuchtgefäss.Wenn die Tiere frei umherschwimmen, kann man auch ein wenig Aquriummoos ins Wasser legen. Damit das Wasser auch weich ist, nimmt man am Besten 2/3 destilliertes Wasser und 1/3 Mineralwasser (ohne Kohlensäure).Wassertemperatur: Temperaturschwankungen im Bereich von +/- 5° C nicht dramatisch.Die ideale Anzuchttemperatur liegt bei 26°.Start:Die Larven schlüpfen nur, wenn diese vom Wasser vollständig umgeben sind. Deshalb die Eier auf einen Klebestreifen und dann dieser ins Wasser legen – so werden die Eier nicht an den Rand geschwemmt und bleiben immer mit Wasser in Berührung.Nach 1-3 Tagen schlüpfen die Larven. Die Larven wachsen schnell heran und können bereits nach bis zu 40 Häutungen in ein bis zwei Wochen die Geschlechtsreife erreichen. Die Männchen halten kurz vor und auch während der Paarung die Weibchen mit ihren Kieferzangen fest. Nach der Paarung entwickeln sich die Eier in den Eisäcken am Hinterleib der Weibchen. Sie fallen auf den Gewässergrund und können im Nährboden mehrere Jahre andauernder Trockenheit überleben.Wenn die Feenkrebse gestorben sind, kann man das Wasser ablassen und den Bodengrund mit den Eiern ganz trocken lassen. Die Larven können nur wieder schlüpfen, wenn die Eier ganz trocken waren.Ist dieser durchgetrocknet, kann ein neuer Ansatz starten.Wenn kein Bodengrund verwendet wird, kann man die Eier auch mit einem dünnen Schlauch absaugen. Das Wasser mit den Eiern durch ein feines Netz oder einen Kaffeefilter fliessen lassen – so kann man die Eier auffangen.Wichtig: Die Tiere vertragen keine grossen Wasserwechsel. Sollen die Feenkrebse in ein grösseres Heim umziehen, gibt man am besten die Tiere mitsamt Anzuchtwasser in das neue Heim oder Becken und füllt langsam mit aufbereitetem Leitungswasser den Behälter auf. Fütterung Die Larven werden ab dem 3. Schlupftag gefüttert.Füttern kann man die Larven mit Algenpulver oder dem JBL Artemio fluid. Für jede Tierhaltung gilt: Kinder müssen von den Eltern angeleitet, beaufsichtigt und kontrolliert werden. Kinder müssen lernen, dass ein Tier seine eigenen Bedürfnisse und Lebensgewohnheiten hat und dies respektieren. Eltern sollten sich darüber bewusst sein, dass sie es sind, die die Verantwortung für das Tier haben. Für Fragen und Probleme steht Ihnen unser ausgebildetes Team im Zoo Roco zur Verfügung. Es kann Sie in allen Fragen fachgerecht beraten.
