Formosa (Chilatini Heterandria formosa, Chingerezi chotsitsa killifish) ndi mtundu wa nsomba za viviparous za banja la Poeciliidae, imodzi mwasamba zazing'ono kwambiri padziko lonse lapansi (7th yayikulu kuyambira 1991). Ndi a banja limodzi lomwe limaphatikizapo nsomba zodziwika bwino zaku aquarium monga ma guppies ndi mollies.
Kukhala m'chilengedwe
Heterandria formosa ndi yekhayo amene ali membala wake ku United States. Ndi imodzi mwasodzi mwa nsomba zaku aquarium zomwe zimapezeka ku North America.
Ndi nsomba yamadzi oyera yomwe imapezekanso m'madzi amchere. Habitat imayendera kumwera chakum'mawa kwa United States, kuchokera ku South Carolina kupita ku Georgia ndi Florida, komanso kumadzulo kudutsa Florida Gulf Coast kupita ku Louisiana. M'zaka zaposachedwa, mtundu uwu wapezeka ku East Texas.
Heterandria formosa amakhala makamaka m'madzi obiriwira, oyenda pang'onopang'ono kapena oyimirira, koma amapezeka m'madzi amchere. Nsomba zimadziwika kuti zimapulumuka mosiyanasiyana.
Kutentha kwamadzi m'malo okhalako kumatha kuyambira 10 degrees Celsius mpaka 32 degrees Celsius (50-90 degrees Fahrenheit).
Zovuta zazomwe zilipo
Amadziwika kuti ndi nsomba zam'malo otentha, koma kuthengo amakhala m'malo osiyanasiyana, chifukwa chake ndi odzichepetsa ndipo amalimbikitsidwa kwa oyamba kumene. Komabe, zimakhala zovuta kuwapeza akugulitsidwa chifukwa cha utoto wanzeru.
Mukamawagula, onetsetsani kuti adadziwika bwino chifukwa nthawi zina amasokonezeka ndi nsomba zowopsa kwambiri za mtundu wa Gambusia.
Kufotokozera
Formosa ndi imodzi mwa nsomba zazing'ono kwambiri komanso zazing'ono kwambiri zomwe zimadziwika ndi sayansi. Amuna amakula mpaka masentimita awiri, pomwe akazi amakula pang'ono, mpaka masentimita atatu.
Nsombazi nthawi zambiri zimakhala ndi azitona, zokhala ndi mizere yakuda yopingasa pakati pathupi. Palinso malo amdima kumapeto kwa dorsal fin; azimayi amakhalanso ndi malo akuda pachimake cha kumatako.
Monga nsomba zambiri za viviparous, amuna amasintha zipsepse zamakolo kupita ku gonopodia, yomwe imagwiritsidwa ntchito kuperekera umuna ndi manyowa azimayi nthawi yokwatirana.
Kusunga mu aquarium
Nthunzi ukhoza kupezeka mu thanki yokhala ndi malita 10 okha. Komabe, popeza amakonda kukhala ochezeka, voliyumu yovomerezeka ndi malita 30.
Popeza kukula kwawo ndikofunikira, pamafunika kugwiritsa ntchito zosefera zamagetsi otsika, chifukwa madzi otuluka mwamphamvu amalepheretsa mawonekedwewo kuyandama.
Ndi mtundu wolimba, chifukwa cha kusinthasintha kwakukulu kwa kutentha kwachilengedwe. Magulu omwe akonzedwa: okhutira 20-26 ° C, acidity pH: 7.0-8.0, kuuma 5-20 ° H.
Kudyetsa
Mitundu yosankhika komanso yamphongo, nsomba zimadya chakudya chochuluka. Amakonda kwambiri daphnia, ndipo chakudyacho chiyenera kukhala ndi gawo lawo. Amakonda kudya ndere m'chilengedwe, chifukwa chake yesani kuphatikiza zomwe mumadya. Popanda algae, ma spirulina flakes ndi abwino m'malo.
Ngakhale
Nsomba zamtendere zam'madzi za aquarium, koma sizoyenera mitundu yonse ya aquarium. Amuna, makamaka, ndi ocheperako kotero kuti amawerengedwa kuti ndi chakudya ndi nsomba zambiri, monga zipsera.
Siziyenera kusungidwa m'madzi okhala ndi nsomba zazikulu, koma zimatha kusungidwa ndi nsomba zina zazing'ono monga ma guppies a Endler, mollies, pecilia, makadinala.
Amuna amatha kuwonetsa kupikisana pang'ono akamalimbana ndi akazi, koma kuwonongeka kwakuthupi pakati pawo ndikosowa kwambiri. Nsomba zimamva bwino zikazingidwa ndi abale, pagulu laling'ono.
Kusiyana kogonana
Amuna ndi ochepa kwambiri kuposa akazi ndipo ali ndi gonopodia yayikulu.
Kuswana
Monga mamembala ambiri amtunduwu, H. formosa ndi viviparous. Amuna amagwiritsa ntchito anal fin, kapena gonopodia, kuti apereke umuna kwa mkazi.
Mazira achonde amakula mkati mwa wamkazi mpaka amaswa ndipo ana osambira mwaulere amatulutsidwa m'madzi.
Komabe, Heterandria formosa ili ndi njira yachilendo yoswana ngakhale pakati pa viviparous: m'malo mongotulutsa mwachangu zonse mwakamodzi, mpaka 40 mwachangu amatulutsidwa munthawi ya masiku 10-14, koma nthawi zina kwa nthawi yayitali.
Kuswana palokha ndikosavuta. Ndizosatheka kupewa ngati amuna ndi akazi ali mgalimoto.
Magawo amadzi ndiosafunika malinga ngati ali mgulu la pamwambapa. Nthawi yolera imakhala pafupifupi milungu inayi. Mudzawona mwachangu angapo akubwera tsiku lililonse kapena awiri ngati muli ndi akazi opitilira mu tanki.
Zimakhala zazikulu kwambiri pakubadwa ndipo zimatha kulandira chakudya chouma chouma ndi brine shrimp nauplii.
Nsomba zazikulu sizimawapweteka.
