Ukungeza okungajwayelekile emthonjeni wakho wokufakelwa kuzovumela ukutholwa kwezinhlanzi zase-aquarium ezibabazekayo njenge-piranhas. Kungabonakala sengathi ukugcinwa komuntu onjalo kungasongela hhayi nje bonke abanye abantu abahlala e-aquarium, kodwa futhi naku-aquarist uqobo. Kodwa lokhu kuyiphutha elijwayelekile, iphutha labo kungokwalabo bomndeni obanzi kakhulu wamaPiranievs, okwenziwa ngaye izindaba zangempela zokuchithwa kwegazi.
Ososayensi bakhombisile ukuthi bangama-40% kuphela abamele lolu hlobo olungasongela impilo yabantu, kanti abanye bangasebenzisa nokudla kwezitshalo njengokudla. Futhi yilokho okwakungokwenhlanzi ethandwayo yePaku, okuzoxoxwa ngayo esihlokweni sanamuhla.
Incazelo
Ungahlangabezana nalezi zinhlanzi ze-aquarium ngokuya e-Amazon Delta. Kepha iminyaka engama-200, ukuze uzitholele isilwane esinjengalesi, kwanele ukuya esitolo sezilwane esiseduze. UPiranhas Paku uthole ukuthandwa kwabo okuphezulu phakathi kwama-aquarists kulo lonke idili ngenxa yokunakekelwa kwabo okungafuneki, usayizi omkhulu nezinga lokukhula, okwenze ukuthi kube lula ukusebenzisela izinjongo zentengiso.
Ngokuqondene nokwakheka komzimba, kubalulekile ukukhetha inombolo efanayo yamazinyo ayisikwele naqonde. Isisindo somuntu omdala singafinyelela kuma-30 kg.
Izinhlobo
Namuhla kunezinhlobo eziningana zezinhlanzi zePaku. Kepha okuvame kakhulu yilezi:
- Paku obomvu.
- Paku omnyama.
Ake sikhulume ngohlobo ngalunye olwethulwe ngokuningiliziwe.
Okubomvu
Endaweni yemvelo, abamele lolu hlobo bangatholakala emachibini aseduze nomfula. Ama-Amazoni. I-Red Paku ihlukaniswa nesimo somzimba esicwecwe, esigcwele ngokuphelele ngezikali ezincane ezinombala wesiliva. Ngokuqondene nefini nesisu, zibomvu ngombala. I-dimorphism yezocansi ibuthakathaka.
Abesifazane bayehluka kwabesilisa ngosayizi omncane nokwakheka okuhle kwesisu. Usayizi omkhulu wabantu abadala endaweni yabo yemvelo ngu-900mm. Ekuthunjweni, ubukhulu bungahluka kusuka ku-400 kuye ku-600 mm. Lezi zinhlanzi ze-aquarium zihlala isikhathi eside. Ubudala oburekhodiwe kakhulu babuyiminyaka engama-28, kepha imvamisa isikhathi sabo sokuphila cishe siyiminyaka eyishumi ekuthunjweni.
Kumele uqaphele isimo sabo esinokuthula. Zidla uhlaza njengokudla. Ngokugcinwa kwabo, amadamu okufakelwa ayadingeka ngevolumu encane yamanzi kusuka kumalitha ayi-100. Amanani wamanzi afanele afaka phakathi amazinga okushisa aphakathi kwama-22-28 degrees nobulukhuni buka-5-20 pH. Futhi, ungakhohlwa ngezinguquko ezivamile zamanzi.

Iqiniso elithandekayo ukuthi ngenxa yalo mbala nokwakheka komzimba, abamele abasha balezi zinhlobo bavame ukudideka nama-piranhas. Ukugwema ukudideka okunjalo, kufanele unake amazinyo aphansi akamuva, aphuma phambili kakhulu.
Kuyaphawuleka ukuthi yize lezi zinhlanzi zingadingi ukunakekelwa okukhethekile, kunzima ukuzigcina ngenxa yobukhulu bazo. Ngakho-ke, ivolumu ephansi yedamu lokufakelwa icishe ibe ngamathani ama-2. amanzi. Amatshe amakhulu nosayizi we-driftwood angasetshenziswa njengezinto zokuhlobisa ngaphakathi komkhumbi onjalo, uma kukhona ongakwazi ukukuthola.

- ubukhulu besibalo sabesilisa kunabesifazane.
Futhi, ukukhetha kwebhokisi lokuzalela kufanele kunqunywe ubukhulu bayo. Njengomthetho, ivolumu yayo ephansi akufanele ibe ngaphansi kwamalitha angama-300. Ngaphezu kwalokho, kufanele ukuthi kubulawe amagciwane kahle ngaphambi kokufaka kuwo abazali besikhathi esizayo. Futhi, imijovo ye-gopophyseal, elandelwa ukuphakelwa okunamandla, ingasetshenziswa njengesikhuthazo esihle.
Ngokuqondene nokudla, inketho ekahle ukufaka ukudla okuvela ezilwaneni kuwo. Lapho izinhlanzi sezikulungele ukukhwelana, zifakwa ebhokisini elizalela.
