I-Metinnis vulgaris

I-Metinnis evamile, igama lesayensi elithi Metynnis hypsauchen, lingelomndeni wakwaSerrasalmidae (Piranidae). Iyisihlobo esiseduze samapiranha asabekayo, kodwa inesimo sokuthula. Iyingxenye yeqembu lezinhlanzi ezibizwa nge-Silver Dollar, ehlanganisa nezinhlobo ze-aquarium ezidumile njenge-Metinnis Spotted, i-Metinnis Lippincotta kanye ne-Silvery Metinnis.

Incazelo

Abantu abadala bafinyelela ubude obuyi-15-18 cm. Izinhlanzi zinomzimba oyindilinga ophakeme oyisicaba kusukela emaceleni. Umbala oyinhloko uyisiliva, amaphiko nomsila kuyashintshashintsha. Ngaphandle, icishe ifane neSilver Metinnis, ngaphandle kokuba khona kwendawo encane emnyama etholakala ngemuva nje ngenhla kwamehlo.

Amaduna ahlukile kwabesifazane ngokuba ne-anal fin ebomvu kanye nombala omnyama ngesikhathi sokuzala.

Ulwazi olufushane:

• Umthamo we-aquarium - kusuka ku-300 amalitha.
• Izinga lokushisa - 24-28 ° C
• Inani pH - 6.0-7.0
• Ubulukhuni bamanzi - athambile (kufika ku-10 dH)
• Uhlobo lwe-substrate - noma yikuphi
• Ukukhanyisa - kuthobile
• Amanzi anosawoti - cha
• Ukunyakaza kwamanzi - ukukhanya noma okuphakathi
• Ubukhulu bezinhlanzi buyi-15-18 cm.
• Ukudla okunomsoco - ukudla okunokuqukethwe okuphezulu kwezingxenye zezitshalo
• Isimo sengqondo - ukuthula
• Ukugcina eqenjini labantu abangu-4-5

habitat

Ivela eNingizimu Melika. Itholakala emifuleni eminingi eshisayo yezwekazi ukusuka eGuyana kuya eParaguay, kuhlanganise nodedangendlale wase-Amazon. Ihlala ezindaweni zemifula enezimila eziminyene zasemanzini.

Ukunakekelwa nokunakekelwa, umhlobiso we-aquarium

Izimo ezifanele zitholakala emanzini afudumele athambile anamanani aphansi okuqina. Ngeqembu labantu abangu-4-5, uzodinga i-aquarium yamalitha angama-300 noma ngaphezulu. Ekwakhiweni, kuyadingeka ukuhlinzeka ngezindawo zokukhosela ngesimo sezihlahla zezitshalo. Kodwa-ke, kufanele kukhunjulwe ukuthi i-Metinnis evamile ijwayele ukulimaza izingxenye ezithambile zezitshalo, ngakho-ke kuyalulekwa ukuthi usebenzise izinhlobo ezikhula ngokushesha ezinamahlamvu aqinile, noma uzikhawulele ezitshalweni zokwenziwa. Ukukhanya kuyancipha.

Ukugcinwa kwe-aquarium kujwayelekile. Ubuncane obuyisibopho buhlanganisa ukufakwa esikhundleni samasonto onke kwengxenye yamanzi ngamanzi ahlanzekile (anamanani afanayo e-pH ne-dH), ukukhishwa kwemfucuza yezinto eziphilayo, ukuhlanza izindonga zethangi ku-plaque nezici zedizayini (uma kunesidingo), ukugcinwa kwemishini.

Ukudla

Isisekelo sokudla kwansuku zonke kufanele siphakelwe ngokuqukethwe okuphezulu kwezakhi zezitshalo, noma izithasiselo ezisekelwe ezitshalweni ezihlukene, isibonelo, ngendlela yama-flakes, ama-granules. Baphinde bamukele ukudla okuphilayo noma okufriziwe okufana ne-bloodworms, i-brine shrimp, njll.

Bangakwazi ukudla omakhelwane abancane be-aquarium, gazinga.

Ukuziphatha Nokuhambisana

Kunconywa ukugcina usayizi weqembu labantu abangu-4-5. Kushuniswe ngokuthula kwezinye izinhlobo ezinkulu, kodwa izinhlanzi ezincane zizosongelwa. I-Metinnis evamile ihlala ikakhulukazi emanzini aphakathi nangaphezulu, ngakho-ke izinhlanzi ezihlala eduze naphansi zizoba abangane abahle. Isibonelo, i-catfish evela ku-Plecostomus ne-Bronyakovs.

Ukuzalanisa / ukuzalanisa

Ukuzala kungenzeka kakhulu ezindaweni zamanzi ane-acidic ethambile ezizungeze u-28°C. Ngokuqala kwenkathi yokuzalanisa, abesilisa bathola ama-shades amnyama, futhi ubomvu buvela endaweni yesifuba. Ngemva kokuqomisana isikhashana, izinhlanzi zizalela amashumi amaningana amaqanda, ziwasakaze ngaphezu komhlabathi ngaphandle kokwenza i-clutch.

Njengomthetho, izinhlanzi ezindala azidli amaqanda azo. Kodwa-ke, ezinye izakhamuzi zase-aquarium zizozijabulela ngokujabula. Ukuze usindise ama-brood, kuyinto efiselekayo ukudlulisa amaqanda ethangini elihlukile. I-Fry ibonakala ngemva kwezinsuku ezintathu. Ekuqaleni, zidla izinsalela ze-yolk sac yazo, bese ziqala ukubhukuda ngokukhululeka zifuna ukudla. Okuphakelayo ngokuphakelayo okuyimpushana okukhethekile, ukumiswa kokuphakela izingane zezinhlanzi zase-aquarium.

Izifo zezinhlanzi

Isizathu esiyinhloko sezifo eziningi okuqukethwe endaweni engafanele. Endabeni yezimpawu zokuqala, kuyadingeka ukuhlola ikhwalithi kanye nokwakheka kwe-hydrochemical yamanzi, uma kunesidingo, buyisela zonke izinkomba esimweni esijwayelekile bese kuphela uqhubekela ekwelashweni. Funda kabanzi mayelana nezimpawu nokwelashwa esigabeni se-Aquarium Fish Diseases.
