IFormosa (i-Latin Heterandria formosa, i-English okungenani i-killifish) iyinhlobo yezinhlanzi ezi-viviparous zomndeni wakwaPoeciliidae, enye yezinhlanzi ezincane kunazo zonke emhlabeni (i-7th ngobukhulu kusukela ngo-1991). Ungowomndeni ofanayo ofaka izinhlanzi ezijwayelekile zase-aquarium njengama-guppies nama-mollies.
Ukuphila emvelweni
IHeterandria formosa ukuphela kwelungu lohlobo lwayo elitholakala e-United States. Ingenye yezinhlanzi ezimbalwa ze-aquarium ezidabuka eNyakatho Melika.
Yinhlanzi yasemanzini angenasawoti etholakala kaningi nasemanzini abilayo. IHabitat inqamula eningizimu-mpumalanga ye-United States, isuka eSouth Carolina iye eGeorgia naseFlorida, nasentshonalanga inqamula iFlorida Gulf Coast iye eLouisiana. Eminyakeni yamuva nje, lolu hlobo lutholakale e-East Texas.
IHeterandria formosa ihlala kakhulu emanzini angenasawoti anezitshalo eziningi, ahamba kancane noma amile, kodwa futhi ayenzeka nasemanzini anosawoti. Izinhlanzi ziyaziwa ukuthi zisinda ezimweni ezihluke kakhulu.
Amazinga okushisa wamanzi ezindaweni zokuhlala angaba kusuka ku-10 degrees Celsius kuya kuma-32 degrees Celsius (50-90 degrees Fahrenheit).
Ukuxakaniseka kokuqukethwe
Babhekwa njengezinhlanzi ezishisayo, kepha endle bahlala ezimeni ezihlukile, ngakho-ke abazithobile futhi banconyelwa abaqalayo. Kodwa-ke, kunzima ukubathola besendalini ngenxa yombala wabo oqondayo.
Lapho uzithenga, qiniseka ukuthi zikhonjwe kahle njengoba kwesinye isikhathi zidideka nezinhlanzi ezinolaka kakhulu lohlobo lweGambusia.
Incazelo
IFormosa ingenye yezinhlanzi ezincane kakhulu nama-vertebrate amancane kunazo zonke ezaziwa yisayensi. Abesilisa bakhula babe cishe ngamasentimitha ama-2, kuthi abesifazane bakhule baba bakhulu, bafike cishe kumasentimitha ama-3.
Inhlanzi imvamisa iluhlaza okomnqumo ngomugqa omnyama ovundlile enkabeni yomzimba. Kukhona nendawo emnyama emphethweni wasemuva; abesifazane nabo banendawo emnyama esinqeni sendunu.
Njengezinhlanzi eziningi ze-viviparous, abesilisa baguqule amaphiko endunu abe yi-gonopodium, esetshenziselwa ukuletha isidoda nokuvundisa abesifazane ngesikhathi sokukhwelana.
Ukugcina ku-aquarium
I-steam ingatholakala kuphela ethangini elingu-10 litre. Kodwa-ke, njengoba bekhetha indlela yokuphila yobungani, ivolumu enconywayo ivela kumalitha angama-30.
Ngokuya ngosayizi wabo omncane, kuyadingeka ukusebenzisa izihlungi zamandla aphansi, ngoba ukugeleza kwamanzi okuqinile kuzovimbela amafomu ukuthi angantanta.
Kuyinto yezinhlobo eziqinile, ngokuya ngokushintshashintsha okukhulu kwamazinga okushisa endaweni yayo yemvelo. Amapharamitha anconyiwe wokuqukethwe: izinga lokushisa 20-26 ° C, i-asidi pH: 7.0-8.0, ubulukhuni 5-20 ° H.
Ukondla
Uhlobo olukhethiweyo futhi oludlayo, izinhlanzi zizodla ukudla okuningi okunikezwayo. Uthanda kakhulu i-daphnia, futhi ukudla kufanele kube nesabelo sabo. Bathanda ukudla ulwelwe emvelweni, ngakho-ke zama ukufaka udaba lwesitshalo ekudleni kwakho. Uma kungekho ulwelwe, ama-spirulina flakes ayindawo enhle.
Ukuhambisana
Izinhlanzi ezinokuthula kakhulu ze-aquarium, kepha azifanele zonke izinhlobo ze-aquarium. Abesilisa, ikakhulukazi, bancane kakhulu ukuthi bazobhekwa njengokudla ngezinhlanzi eziningi kakhulu, njengama-scalars.
Akufanele zigcinwe kuma-aquariums nezinhlanzi ezinkulu, kepha zingagcinwa nezinye izinhlanzi ezincane ezinjenge-Endler's guppies, mollies, pecilia, cardinal.
Abesilisa bangakhombisa ukuhlukumezeka okuncane lapho bencintisana nabesifazane, kepha ukulimala ngokomzimba phakathi kwabo akuvamile. Inhlanzi izizwa ingcono uma izungezwe yizihlobo, ngomhlambi omncane.
Ukungafani ngokocansi
Abesilisa bancane kakhulu kunabesifazane futhi bane-gonopodia enkulu.
Ukuzala
Njengamalungu amaningi ohlobo, uH. Formosa uviviparous. Owesilisa usebenzisa i-anal fin yakhe, noma i-gonopodia, ukuletha isidoda kowesifazane.
Amaqanda avundisiwe akhula ngaphakathi kowesifazane aze achanyuselwe futhi amawundlu abhukuda mahhala adedelwa angene emanzini.
Kodwa-ke, iHeterandria formosa inecebo elingavamile lokuzalisa, ngisho naphakathi kwama-viviparous: esikhundleni sokukhipha konke ukuthosa ngasikhathi sinye, kukhishwa kuze kube ngamafry angama-40 ngesikhathi sezinsuku eziyi-10-14, kepha kwesinye isikhathi isikhathi eside.
Ukuzalanisa uqobo kulula kakhulu. Cishe akunakwenzeka ukuyivimba uma ngabe bobabili abesilisa nabesifazane bakhona ethangini.
Amapharamitha wamanzi akanandaba ukuthi aphakathi kwamabanga angenhla. Isikhathi sokukhulelwa cishe amasonto ama-4. Uzobona amafry amaningana avela nsuku zonke noma amabili uma unabesifazane abangaphezu koyedwa ethangini.
Mikhulu impela lapho izalwa futhi ingamukela ngokushesha ukudla okwomile okuyimpuphu ne-brine shrimp nauplii.
Izinhlanzi ezindala ngokuvamile azibalimazi.
