Helena hozhwa: kuchengetedza, kubereka, tsananguro, mufananidzo, kugarisana.

Helena hozhwa yakanaka kwazvo uye inobatsira mvura yakachena mollusk iyo ichave inonakidza uye inonakidza kuona. Nekudaro, mamwe maficha ezvirimo anofanira kuverengerwa. Hozhwa yeHelena imhuka inodya mhuka dzemvura yakachena. Kazhinji, maaquarist anosarudza kuvabereka, avo vasingakwanise kuzvimiririra kudzora nhamba kana vasingakwanise kubvisa zvachose hozhwa dzakawira mumvura, semuenzaniso, phys, coils, melania.

KUTSANANGURWA

Clea helena (Meder muPhilippi, 1847), aimbove Anentome helena, ndeimwe yemhando nhanhatu dzerudzi Clea rakanyorwa kubva kuMalaysia, Indonesia, Thailand neLaos. Pakutanga, mollusk yakatsanangurwa pachitsuwa cheJava (Van Benthem Jutting 1929; 1959; Brandt 1974). Clea helena inhengo yemhuri yeBuccinidae, kazhinji marine gastropod mollusk. Nzvimbo yaro haigumiri kunzizi, hozhwa inogarawo mumadziva nemadziva (Brandt 1974).

Vamiriri veiyo genus Clea vakanyoreswa muAsia pamapani ealluvial uye padyo nenzvimbo dzakakura dzemvura, semuenzaniso, Ayeyarwaddy River Delta (Myanmar), Mekong River (Indochina), Rwizi Chao Phraya (Thailand) nemamwe mahombe enzizi nemadziva. yeMalaysia, Brunei neIndonesia (Sumatra, Java, Kalimantan, SiputKuning, 2010). Zvizvarwa zvevanhu hazviwanikwe kune dzimwe nzvimbo,

zvisinei, rudzi rwava ubiquitous pakati aquarist muNorth America, Europe, uye Asia. Alluvial plain - bani rinomuka semugumisiro wekuita kwekuunganidza kwenzizi huru. Kunyanya mapani ane alluvial anomuka apo nzizi dzinodzungaira munzvimbo dzetectonic subsidence. Muchisikigo, helena inogara pasi pemvura yakasviba, saka haina kufanira kumakemikari emvura. Zvisinei, sezvo mhuka dzacho dziri munzvimbo dzinopisa, tembiricha yakaderera inoiuraya.

Snail content

Kugona kwe 3-5 litita kunokwana kuvapo kwakanaka kwemunhu mumwe chete, asi zviri nani kupa imwe nzvimbo - kubva pa15 litita. Muchiitiko ichi, Helena achatarisa zvakanyanya kutaura uye ane hupenyu. Kuchengetwa kwehozhwa kunofanira kuitika mumvura ine tembiricha ye23-27 ° C. Kana iyo thermometer inodonha kusvika 20 ° C kana pasi, ipapo shellfish haigoni.

achakwanisa kubereka. Zvakakosha kutarisira humwe hunhu hwemvura: iyo acidity yemvura inofanira kunge iri pakati pe7.2-8 pH; kuoma kwemvura - kubva pa8-15. Kunyanya kukoshesa kunofanira kubhadharwa pakusarudzwa kwevhu. Kuna Helen, jecha kana matombo achaita. Kusiyana nemhando dzakawanda dzemollusks, rudzi urwu haruna kunyura zvachose muvhu; hozhwa yeHelena inotsvaka zvokudya mairi.

Iyo nharaunda aquarium haisi nzvimbo yakanaka yekungotenga maclams, havazokwanise kuwana huwandu hwekudya uye vangangofa. Zvichave zvakanaka kana kuchengetedza pamatanho ekutanga ehupenyu kunoitika mune imwe aquarium yakasiyana, uko hozhwa dzinogona kukura kusvika 1 cm. Kana pane akawanda madiki mollusks (melania, coils) mu aquarium, saka unogona kukanganwa nezvekudya kwaHelen. Kana ivo vasipo, saka chero chikafu chakapfuma mumapuroteni chichaita.

Zvinodiwa nemvura

Zvinofanira kucherechedzwa kuti Helena hozhwa haana kuzvikudza zvachose. Zviri mukati maro, zvichienderana nemimwe mitemo, hazvigadziri matambudziko. Marita mashanu emvura anokwana hozhwa imwe chete, asi zviri nani kana iine nzvimbo yakasununguka - kusvika pamarita makumi maviri. Iva nechokwadi chokuti mvura yakaoma. Mumvura yakapfava, hozhwa yakaipa, nekuti goko rayo rinoda zvicherwa. Iyo yakanyanya kugadzikana tembiricha yemvura ndeye 21-23 ° C pamusoro pe zero.

Painodonha pasi pe +19°C, Helena anogona kurega kudya. Iwe unogona kudyara chero zvirimwa mu aquarium, sezvo hozhwa dzisina hanya nazvo. Hunhu hwevhu hunokosha zvikuru. Kusiyana nemamwe marudzi ehozhwa, helens haiputi zvachose mairi, asi tsvaga zvokudya ipapo, saka jecha kana matombo akanaka anonyatsokodzera chinangwa ichi.

Kudyisa

Hozhwa yehelena ishamwari hombe yemamoluska akadai semakoiri, ane fizy uye, kashoma, melania. Asarudza munhu akabatwa, Helena anotambanudza proboscis nemuromo wakavhurika mugoko chaimo uye anotanga kusveta kunze zviri mukati, achisiya goko risina chinhu semhedzisiro. Pamusoro pehozhwa dzakakura, semuenzaniso, hozhwa kana tilomelanium, haarwise, nekuti haakwanise kuikunda. Hozhwa inodya nyama haibati kunyange hozhwa diki, idzo dzine magomba ayo proboscis haigoni kukambaira.

Helena anogona uye anofanira kudyiswa nechikafu chekuwedzera, kunyanya kana asina kutanga kudya hozhwa dzakachengetwa. Vanodya zvakasara zvehove chikafu, vachishingaira kuzvibata kune bloodworms, shrimp yakaoma, catfish chikafu. Muzvisikwa, Helena anowanzodya zvakaora. Izvi zvinogoneka zvakare muaquarium - vanhu vanorwara zvakanyanya kana vakafa vanogona kudyiwa nehozhwa.

kugarisana

Helena anongounza kutyisidzira kune hozhwa diki. Anogara achiwirirana nehove, uye kana akarwisa, ipapo chete pamunhu anorwara zvikuru uye asina simba. Swift shrimp zvakare haina kuverengerwa mune rondedzero yevakabatwa naHelena, asi, sezvehove, vamiriri vasina kusimba vasina kushivirira molting vanogona kuve chinangwa. Mhando dzisina kujairika dze shrimp dzinonyanya kuchengetwa zvakasiyana.

Kufanana nehozhwa dzakawanda, helena anodya mazai ehove, asi haabati fry: anowanzoita nimble, uye hozhwa haigoni kuvabata.

Nhau dzakanaka kune vanoda aquarium chirimwa! Hozhwa dzakawanda, kana pane kushaya zvokudya, dzinotanga kurwisa algae, zvichiita kuti dzikuvadze zvakanyanya. Helena snails haina hanya zvachose nemiti.

rutoto

Hozhwa dzaHelen dzine vanhukadzi, saka kuberekana kwadzo kunoda kuvepo kwevanhu vaviri. Sezviri munyaya yehozhwa, hazvibviri kusiyanisa mukadzi kubva kumurume, saka zviri nani kutenga zvimedu zvakawanda panguva imwe chete, kuitira kuti pakati pavo pane zvingangoita zvepabonde. Mumamiriro ezvinhu akanaka, vanobereka zvakasimba: mukadzi mumwe chete anogona kukandira mazai mazana maviri pagore.

Kugadzirira kusangana, hozhwa dzinova dzisingaparadzanisiki kwenguva yakati: dzinokambaira pamwe chete, dzinodyisa, dzinokwirana. Kuwana akati wandei mahelens akagadzirwa, zviri nani kuvadyara mune yakaparadzana aquarium. Kuvakidzana nehove dzinoshanda kuchava nekuora mwoyo kumukadzi, uye haazokwanisi kuisa mazai.

Kusvirana idanho rakareba, rinogona kutora maawa akati wandei. Mushure meizvi, mukadzi anokandira zai rake panzvimbo yakaoma: matombo, driftwood kana zvimwe zvekushongedza zvemu aquarium. Iro mutsamiro wakajeka, mukati mayo yellow caviar yakavanzwa. Caviar inoibva mukati memavhiki maviri-2.

Kana hozhwa duku ikachochonya, inobva yangozviwana iri pasi, yobva yahwanda muvhu. Ikoko inogara kwemwedzi inoverengeka kusvikira yasvika pakukura kwemamirimita mashanu-5.

Helena ndiye akakwana aquarium mubatsiri kudzikamisa ine dutu ruvara rwe clams inodya zvese zvakatenderedza. Zvirimo hazvina kunetsa, uye akawanda wongororo anoratidza kuti chikara chidiki hachingobatsiri chete, asiwo chinova chinhu chinoshamisa chekushongedza kwe aquarium.
