Nkhono zam'madzi oyera helena (Latin Anentome helena) imapezeka ku Southeast Asia ndipo nthawi zambiri imadziwika kuti nkhono kapena nkhono. Mayina ake asayansi ndi Anentome helena kapena Clea helena.
Gawoli limakhazikitsidwa pamitundu iwiri - Clea (Anentome) yamitundu yaku Asia ndi Clea (Afrocanidia) yamitundu yaku Africa.
Chofunika kwambiri pamtunduwu ndikuti amadya nkhono zina, ndiye kuti ndi nyama yolusa. Zomwe amadzi am'madzi aphunzira kugwiritsa ntchito ndi zomwe ali nazo zochepetsera kapena kuthetsa mitundu ina ya nkhono m'madzi.
Kukhala m'chilengedwe
Ambiri a Helen amakonda madzi, koma amatha kukhala m'madzi ndi m'mayiwe, mwina ndi chifukwa chake amasinthasintha bwino momwe zinthu zilili m'nyanja. Mwachilengedwe, amakhala pamadambo amchenga kapena amtambo.
Mwachilengedwe, ndi nyama zolusa zomwe zimadya nkhono zamoyo zonse, ndipo izi ndi zomwe zimawapangitsa kukhala otchuka kwambiri mu aquarium.
Chipolopolocho chimakhala chowoneka bwino, chokhala ndi nthiti; nsonga ya chipolopolocho nthawi zambiri imakhalapo. Chipolopolocho ndi chachikasu, ndi mzere wakuda wakuda mwauzimu.
Thupi limakhala lobiriwira. Kukula kwakukulu kwa chipolopolo ndi 20 mm, koma nthawi zambiri pafupifupi 15-19 mm.
Kutalika kwa moyo ndi zaka 1-2.
Amakhala ku Indonesia, Thailand, Malaysia.
Kusunga mu aquarium
A Helens ndi olimba komanso osavuta kusamalira.
Monga nkhono zina zambiri, zimamverera m'madzi ofewa kwambiri, chifukwa zimafunikira mchere wazipolopolo zawo. Ngakhale magawo amadzi sali ofunika kwambiri, ndibwino kuti musunge m'madzi owuma kapena olimba, okhala ndi pH ya 7-8.
Nkhonozi ndi madzi abwino ndipo sizifuna madzi amchere. Koma amalekerera mchere pang'ono.
Umenewu ndi mtundu womwe umakwiriridwa panthaka, ndipo umafuna dothi lofewa, mchenga kapena miyala yabwino kwambiri (1-2 mm), Pangani nthaka yotere yomwe ili pafupi kwambiri, popeza itatha kudya imaboola pansi kapena pang'ono ...
Ayeneranso kukhala ofunitsitsa kuswana m'nyanja yamchere yokhala ndi nthaka yofewa, chifukwa anyamatawo amaikidwa m'manda nthawi yomwe abadwa ndipo nthawi yawo yambiri amakhala m'nthaka.
Makhalidwe mu aquarium:
Kudyetsa
Mwachilengedwe, chakudyacho chimakhala ndi zovunda, komanso chakudya chamoyo - tizilombo ndi nkhono. Mu aquarium, amadya nkhono zambiri, mwachitsanzo - nat, coils, melania. Komabe, Melania ndiye wodya kwambiri.
Nkhono zazikulu monga neretina wamkulu, ampullary, mariza kapena tylomelanias zazikulu sizili pangozi. Helena sangakwanitse. Amasaka pomata chubu chapadera (kumapeto kwake komwe kumatseguka pakamwa) mu chipolopolo cha nkhono ndikuyiyamwa.
Ndipo ndi nkhono zazikulu, sangathe kubwereza chinyengo ichi. Mofananamo, nsomba ndi nkhanu, zimathamanga kwambiri kwa iye, ndipo nkhonoyi siinasinthidwe kusaka nkhanu.
Kubereka
Helens amaswana mosavuta m'nyanja yamchere, koma nkhono nthawi zambiri zimakhala zochepa.
Awa ndi nkhono zogonana amuna kapena akazi okhaokha, osati ma hermaphrodites, komanso kuti muswane bwino muyenera kusunga nkhono zingapo kuti muwonjezere mwayi wakulera anthu omwe amagonana amuna kapena akazi okhaokha.
Kukondana kumachedwa ndipo kumatha kutenga maola. Nthawi zina nkhono zimalumikizana ndi awiriwo ndipo gulu lonse limalumikizidwa.
Mkazi amayikira dzira limodzi pamalo olimba, miyala kapena mitengo yolowerera mu aquarium.
Dzira limakula pang'onopang'ono, ndipo pomwe anawo amaswa, kenako amagwera pansi nthawi yomweyo amabisala ndipo simudzawawona kwa miyezi ingapo.
Pafupifupi nthawi pakati pa dzira ndikuwotchera mwachangu mu aquarium ndi pafupifupi miyezi 6. Mwachangu amayamba kuwonekera poyera akafika pakukula pafupifupi 7-8 mm.
Mwa nkhono zoswedwa, ochepa amapulumuka mpaka kukhala achikulire.
Mwachiwonekere, chifukwa chake ndikudya anthu anzawo, ngakhale akuluakulu samakhudza achinyamata, komanso, kwakukulu, pampikisano wapa chakudya panthawi yakukula pansi.
Ngakhale
Monga tanenera kale, ndizoopsa kokha nkhono zazing'ono. Ponena za nsombazo, zili zotetezeka kwathunthu, nkhono imatha kumenya nsomba zodwala kwambiri ndikudya yakufayo.
Nkhanu ndizothamanga kwambiri kuti zitheke nkhonozi, kupatula kuti zosungunuka zitha kukhala pachiwopsezo.
Ngati musunga mitundu yosowa ya shrimp, ndibwino kuti musayike pachiwopsezo ndikuwapatula ndi helen. Monga nkhono zonse, imadya mazira a nsomba ngati ingafike. Mwachangu, ndizotetezeka, bola ngati zikuyenda kale.
Malinga ndi zomwe akatswiri am'madzi akuwona, helena imatha kuchepetsa kapena kuwononga nkhono zina zam'madzi.
Popeza kuti nthawi zonse pamakhala zovuta zambiri, ntchito yanu ndikusintha ndalamazo kuti mukhale ndi mitundu yambiri ya nkhono m thanki yanu.
