Iris enemigqa emithathu noma i-melanothenia enemigqa emithathu (Latin Melanotaenia trifasciata) ingenye yezinhlanzi ezigqame kakhulu emndenini. Yinhlanzi encane ehlala emifuleni yase-Australia futhi yehlukile kweminye iris lapho kukhona imivimbo emnyama emzimbeni.
Imizila emithathu iqukethe zonke izici ezinhle zomndeni: inemibala egqamile, kulula ukuyigcina, iyasebenza kakhulu.
Isikole salezi zinhlanzi ezisebenzayo, kepha ezinokuthula siyakwazi ukudweba ngisho ne-aquarium enkulu kakhulu ngemibala egqamile.
Ngaphezu kwalokho, ilungele kahle abaqalayo njengoba ikwazi ukubekezelela izimo zamanzi ezahlukahlukene.
Ngeshwa, abantu abadala bale iris abavamile ukutholakala besendalini, futhi intsha etholakalayo ibukeka iphaphathekile. Kodwa ungathukutheli!
Isikhathi esincane nokunakekelwa futhi izovela phambi kwakho ngayo yonke inkazimulo yayo. Ngokushintshwa kwamanzi njalo, ukondla kahle nokuba khona kwabesifazane, abesilisa bazokhanya kungekudala.
Ukuphila emvelweni
Imizila emithathu yeMelanothenia yachazwa okokuqala nguRandall ngo-1922. Uhlala e-Australia, ikakhulu engxenyeni esenyakatho.
Izindawo zalo zokuhlala zilinganiselwe kakhulu: iMelville, iMarie River, i-Arnhemland, neGroot Island. Njengomthetho, bahlala emifudlaneni nasemachibini agcwele izitshalo kakhulu, bahlangana ngemihlambi, njengabo bonke abanye abamele.
Kepha futhi zitholakala emifuleni, emaxhaphozini, ngisho nasezomeni zamanzi ngesikhathi sonyaka esomile. Inhlabathi ezindaweni ezinjalo inamadwala, imbozwe ngamaqabunga awile.
Incazelo
Imigqa emithathu ikhula cishe ngo-12 cm futhi ingaphila kusuka eminyakeni emi-3 kuye kwengu-5. Okujwayelekile ngesakhiwo somzimba: ukucindezelwa kamuva, ikhanda eliphakeme kanye nekhanda elincane.
Uhlelo ngalunye lomfula lapho kuhlala khona imizila emithathu luwanikeza umbala ohlukile.
Kepha, njengomthetho, zibomvu ngokugqamile, zinemibala ehlukahlukene emzimbeni nomugqa omnyama phakathi.
Kunzima kokuqukethwe
Ngokwemvelo, i-melanothenia enemizila emithathu kufanele ivumelane nezimo ezahlukahlukene ukuze iphile.
Okubanikeza inzuzo lapho kugcinwa emanzini. Babekezelela izimo ezahlukahlukene kahle futhi bayamelana nezifo.
Ukondla
Omnivorous, emvelweni bondla ngezindlela ezahlukahlukene, ekudleni izinambuzane, izitshalo, ama-crustaceans amancane kanye nefry. Kokubili ukudla okwenziwe nokuphila kungaphakelwa ku-aquarium.
Kungcono ukuhlanganisa izinhlobo ezahlukene zokudla, njengoba umbala womzimba uncike kakhulu ekudleni. Cishe abakaze bathathe ukudla kusuka phansi, ngakho-ke kubalulekile ukuthi ungadlisi ngokweqile futhi ugcine i-catfish.
Ngaphezu kokudla okuphilayo, kungakuhle ukwengeza imifino, ngokwesibonelo amahlamvu ka ulethisi, noma ukudla okuqukethe i-spirulina.
I-aquarium enama-irises ahlukahlukene:
Ukugcinwa nokunakekelwa ku-aquarium
Njengoba inhlanzi inkulu impela, inani eliphansi lokuncoma lokugcina lisuka kumalitha ayi-100. Kepha, okuningi kungcono, ngoba umhlambi omkhulu ungagcinwa ngevolumu enkulu.
Zigxuma kahle, futhi i-aquarium idinga ukumbozwa ngokuqinile.
Imizila emithathu ayinantobeko kumapharamitha nokunakekelwa kwamanzi, kepha hhayi kokuqukethwe kwe-ammonia ne-nitrate emanzini. Kungakuhle ukusebenzisa isihlungi sangaphandle, futhi bayakuthanda ukugeleza futhi abakwazi ukwehliswa.
Umuntu angabona ukuthi umhlambi ume kanjani maqondana nesikhathi samanje futhi uzama nokulwa nawo.
Amapharamitha wamanzi wokuqukethwe: izinga lokushisa 23-26C, ph: 6.5-8.0, 8 - 25 dGH.
Ukuhambisana
Imizila emithathu yeMelanothenia ihamba kahle nezinhlanzi ezilingana ngokulinganayo emanzini amakhulu.Nakuba zingenalo ulaka, zizokwethusa izinhlanzi ezinamahloni ngomsebenzi wazo.
Bazwana kahle nezinhlanzi ezisheshayo njengeSumatran, izikhuni zomlilo noma i-denisoni. Ungaqaphela ukuthi kunezingxabano phakathi kwe-iris, kepha njengomthetho, ziphephile, izinhlanzi azivamisile ukulimazana, ikakhulukazi uma ziqukethwe emhlambini, hhayi ngababili.
Kepha noma kunjalo, bhekisisa ukuze inhlanzi ehlukile ingajahwa, nokuthi ingaba nendawo yokufihla.
Le yinhlanzi efunda isikole futhi isilinganiso sabesilisa nabesifazane sibaluleke kakhulu ukuze kungabikho zimpi.
Yize kungenzeka ukugcina izinhlanzi zocansi olulodwa kuphela e-aquarium, zizokhanya kakhulu lapho kugcinwa ndawonye abesilisa nabesifazane. Ungazulazula cishe ngesilinganiso esilandelayo:
- Imizila emi-3 emithathu - ucansi olulodwa
- I-6 enemigqa emithathu - abesilisa abathathu + abesifazane abathathu
- I-7 enemigqa emithathu - abesilisa abathathu + abesifazane aba-4
- 8 okunemishwe emithathu - abesilisa abathathu + abesifazane aba-5
- I-9 enemigqa emithathu - abesilisa abane + abesifazane aba-5
- I-10 enemigqa emithathu - abesilisa abahlanu + abesifazane aba-5
Ukungafani ngokocansi
Kunzima ukuhlukanisa owesifazane kowesilisa, ikakhulukazi phakathi kwentsha, futhi imvamisa bathengiswa njengefry.
Abesilisa abavuthiwe ngokobulili banemibala egqame kakhudlwana, benomhlane oholile ngokwengeziwe, nokuziphatha okunolaka ngokwengeziwe.
Ukuzala
Ezindaweni zokuzalela, kungakuhle ukufaka isihlungi sangaphakathi bese ubeka izitshalo eziningi ezinamaqabunga amancane, noma intambo yokwenziwa, njengendwangu yokuwasha.
Ukukhiqizwa kabusha kwe-iris yemizila emithathu kuyasebenza futhi kusuthiswa ngaphambili ngokudla okuphilayo, ngokufakwa kokudla kwezitshalo.
Ngakho-ke, ulingisa ukuqala kwenkathi yemvula, okuhambisana nokudla okuningi. Ngakho-ke okuphakelayo kufanele kube kukhulu kunokujwayelekile futhi kube nekhwalithi ephezulu.
Kutshalwa ipheya lezinhlanzi ezindaweni ezizalela kuzo, ngemuva kokuthi insikazi isilungele ukuzala, abalingani besilisa bayaye bavundise amaqanda.
Lo mbhangqwana ubeka amaqanda izinsuku ezimbalwa, ngalinye lizala inani lamaqanda liyakhula. Ababelethi badinga ukususwa uma inani lamaqanda lincipha noma uma bekhombisa izimpawu zokwehla.
Fry hatch ngemuva kwezinsuku ezimbalwa bese uqala ukondla ngama-ciliates nokuphakelwa kuketshezi kathosi, baze badle i-Artemia microworm noma i-nauplii.
Kodwa-ke, kungaba nzima ukukhula ngefry. Inkinga ise-interspecies crossing, ngokwemvelo ayiwele nezinhlobo ezifanayo.
Kodwa-ke, e-aquarium, izinhlobo ezahlukahlukene ze-iris ziyazalana zodwa ngemiphumela engalindelekile.
Imvamisa, ukuthosa okunjalo kulahlekelwa umbala ogqamile wabazali babo. Njengoba lezi kuyizinhlobo ezingandile impela, kungakuhle ukuthi ugcine izinhlobo ezahlukene ze-iris ngokwehlukana.
