Iyi ndiye haracin yayikulu kwambiri yomwe imakhala ku South America ndipo siyimafanana ndi anzawo ang'onoang'ono.
Nsombazo zimakula mpaka masentimita 108 m'litali ndipo zimalemera pafupifupi 27 kg, zomwe ndizodabwitsa. Komabe, amakhalabe ochuluka kwambiri mwa masentimita 70, koma ngakhale izi ndizoletsa kwa aquarium ya amateur. Nzosadabwitsa kuti amatchedwanso chimphona pacu.
Kukhala m'chilengedwe
Black pacu (kapena bulauni), yoyamba kufotokozedwa ndi Cuvier mu 1816. Timakhala mumtsinje wonse wa Amazon ndi Orinoco ku South America.
Kanema wonena za nkhokwe yachilengedwe ku Brazil, kumapeto kwa kanemayo, kuwombera m'madzi, kuphatikiza gulu lankhosa
Mu 1994 adabweretsedwa ku Guinea ngati nsomba zamalonda, mumitsinje ya Sepik ndi Rama. Komanso imafalikira ku South America konse, kuphatikizapo Peru, Bolivia, Colombia, Brazil, Cuba, Dominican Republic, Honduras. Ndi Kumpoto - USA.
Zowonongera zimadya tizilombo, nkhono, zomera zowola ndi nsomba zazing'ono.
Nsomba zazikulu zimasambira m'nkhalango zomwe zimasefukira m'nyengo yamvula ndipo zimadya zipatso ndi mbewu.
Ator akuti amadya zipatso zomwe zagwera m'madzi, zomwe ndizochuluka pamenepo.
Kufotokozera
Black pacu imatha kukula mpaka 106 cm ndikulemera mpaka 30 kg ndikukhala zaka 25. Thupi limapanikizika pambuyo pake, mtundu wa thupi umakhala wakuda mpaka wakuda, nthawi zina ndimadontho m'thupi. Zipsepsezo ndi zakuda.
Nthawi zambiri zimasokonezedwa ndi ma piranhas akadali ang'ono. Juveniles ndi ofanana kwambiri, koma pacu yakuda ndiyokulungika komanso yotakata kuposa ma piranhas.
Njira yosavuta ndiyo kudziwa ndi nsagwada yakumunsi, mu piranha imayenda patsogolo.
Zovuta pakukhutira
Ndi nsomba yayikulu kwambiri ndipo imasungidwa bwino m'malo am'madzi ogulitsa, chifukwa anthu ambiri sangakwanitse kugula kunyumba. Ngakhale ndizodzichepetsa komanso zosavuta.
Osakakamira magawo amadzi, bola ngati sakhala owopsa, chimodzimodzi pakudya.
Black pacu ndi nsomba yochititsa chidwi, yosamalira kwambiri komanso yosamalira, yomwe imakhalanso ndi umunthu wake. Zikumveka ngati nsomba yabwino kwambiri yam'madzi, sichoncho?
Koma vuto lalikulu posunga ndikuti nsombazi zimakula mwachangu komanso zazikulu, ngakhale zamadzi zazikulu kwambiri, zimakula msanga.
Vuto ndiloti nthawi zambiri ogulitsa osasamala amawapangitsa kukhala ochepa kwambiri podzitcha kuti ma piranhas. Ngakhale kuti nsombazi ndizofanana, pacu sichikhala choopsa komanso chosadya nyama.
Komabe, sizikutsutsa kuti nsomba yaying'ono iliyonse mu aquarium idzamezedwa mosazengereza.
Izi sikuti ndi nsomba kwa aliyense. Kuti musunge imodzi, mufunika malita 1000 a ana, ndipo pafupifupi 2000 ya nsomba yayikulu.Pamadzi oterewa, mumafunikira galasi lokulirapo kwambiri, chifukwa mwamantha nsomba zitha kuthyola.
M'madera ofunda, nthawi zina nsomba zimasungidwa m'mayiwe, osati chifukwa chakuda, sizimawoneka bwino kumeneko.
Ngati simukuwopa kuchuluka komwe kumafunikira nsomba iyi, ndiye kuti sizovuta kusamalira.
Kudyetsa
Omnivorous, mwachilengedwe amadya zipatso, chimanga, tizilombo, nkhono, zopanda mafupa, zowola. Madzi a m'nyanjayi azidya zakudya zopangira komanso zamoyo.
Chilichonse chimuyenera - nkhono, nyongolotsi, ma virus a magazi, zipatso, ndiwo zamasamba. Ndi nsomba zazing'ono, ndiye kuti sizoyenera kusungika ndi zomwe pacu imeza.
Kusunga mu aquarium
Chofunikira chachikulu ndi aquarium yayikulu kwambiri, kwa akulu ochokera matani 2. Ngati mungakwanitse, zovuta zimathera pomwepo.
Amachotsera malo amodzi, osagwidwa ndi matenda, ndipo amadya chilichonse. Chokhacho ndichakuti kusefera kwamphamvu kwambiri ndikofunikira, popeza kuli dothi lochokera kwa iwo.
Amakhala pakati pamadzi ndipo amafunikira malo osambira mwaulere.
Zokongoletsa zabwino kwambiri ndi mitengo yolowerera ndi miyala yayikulu, mbewu sizingabzalidwe konse, ndi chakudya cha paketi.
Kuyenda mwamanyazi pang'ono, kwakuthwa ndipo ali ndi mantha, kuponyera mozungulira aquarium ndikuphulika ndi zinthu ndi galasi ...
Ngakhale
Akuluakulu amakhala okha, koma osati mwamakani. Achinyamata ndi tambala kwambiri. Akuluakulu amadya nsomba zing'onozing'ono zomwe amatha kumeza, nsomba zazikulu sizili pangozi.
Zosungidwa bwino zokha kapena ndi nsomba zazikulu mofananamo.
Kusiyana kogonana
Yamphongo imakhala ndi chakuthwa chakuthwa chakuthwa, kumatako ili ndi msana, ndipo imawala kowala kuposa chachikazi.
Kuswana
Black pacu siyimera m'madzi a aquarium chifukwa cha kukula kwake.
Anthu onse ogulitsa amagulitsidwa m'madziwe komanso m'mafamu.
