M'zaka zaposachedwa, akhalanso ku California ndi Nevada. Izi zidatheka chifukwa chamadzi osasamala omwe amatulutsa nsomba zowononga m'madzi am'deralo.
Mwachilengedwe, nsomba imadya chilichonse chomwe chingameze. Amadyetsa nsomba, komanso amadya tizilombo tambiri. Zakudya zazomera zimapanga gawo laling'ono lazakudya zake.
Monga tanenera kale, ngati kuli kotheka, nsomba zimadumphira m'madzi ndikugwira mbalame zikuuluka kapena kukhala panthambi. Kuphatikiza apo, anyani, akamba, ndi makoswe amapezeka m'mimba mwa nsomba zomwe zidagwidwa.
Arowana ndi gawo lofunikira kwambiri m'moyo wapafupi. Amakhala wofunidwa kwambiri nawo ndipo amabweretsa ndalama zambiri kwa asodzi.
Nyama ndi yamafuta ochepa ndipo imakoma. Amagulitsidwanso kwa ogulitsa nsomba za m'deralo.
Komanso, amadziwika kuti ndi imodzi mwa nsomba zotsika mtengo kwambiri. Platinyo yosowa kawirikawiri inaperekedwa $ 80,000, koma mwiniwakeyo anakana kugulitsa, ponena kuti inali yamtengo wapatali.
Kufotokozera
Silver Arowana ndi nsomba yayikulu kwambiri, yomwe imatha kufika masentimita 120. Ili ndi thupi lalitali, longa njoka ndipo imafunikira nyanja yamadzi osachepera 4 kuti isunge.
Komabe, nsomba zamtunduwu ndizosowa kwambiri m'nyanja yam'madzi, nthawi zambiri zimakhala zazitali masentimita 60-80.
Pa nthawi imodzimodziyo, akhoza kukhala ndi moyo mpaka zaka 20, ngakhale ali mu ukapolo.
Pakamwa pa Arowana amatseguka magawo atatu ndipo imatha kumeza nsomba zazikulu kwambiri. Alinso ndi lilime la mafupa, ndipo mafupa mkamwa mwake ali okutidwa ndi mano. Pakona pakamwa pake pali ndevu ziwiri zomwe zimakonda kupeza nyama.
Ndi chithandizo chawo, nsomba zimatha kuzindikira nyama ngakhale mumdima wandiweyani. Kupatula apo, imakhalanso ndi maso owoneka bwino kwambiri, imatha kuwona nyama pamwamba pamadzi, nthawi zina imalumpha ndikunyamula tizilombo ndi mbalame kuchokera kuma nthambi apansi amitengo.
Chifukwa cha ulesi, adatchulidwanso - nyani wamadzi.
Zovuta pakukhutira
Nsomba si za oyamba kumene. Arowana amafunika malo osungira kwambiri, ngakhale aang'ono, chifukwa amakula msanga.
Kwa achinyamata, malita 250 ndi okwanira, koma adzafunika msanga malita 800-1000. Muyeneranso madzi oyera kwambiri.
Komabe, monga nsomba zambiri zomwe zimakhala mumitsinje, zimakhala zosagwirizana ndi kusintha kwa pH ndi kuuma. Kuphatikiza apo, kuzidyetsa ndizosangalatsa kwambiri.
Chimodzi mwazinthu zosangalatsa kwambiri za Arowana ndi pakamwa pake. Amatseguka magawo atatu ndipo amafanana ndi phanga, lomwe limatiuza za nyama yolusa komanso yosakhutitsidwa.
Ngakhale zidakali zazing'ono, zimatha kusungidwa ndi nsomba zina, zazikuluzikulu zimasungidwa bwino zokha kapena ndi nsomba zazikulu kwambiri. Ndi nyama zolusa zabwino ndipo zimadya nsomba zazing'ono zilizonse.
Mosakayikira, awa ndi ma jumpers abwino ndipo aquarium iyenera kutsekedwa mwamphamvu nthawi zonse.
Kudyetsa
Omnivorous, mwachilengedwe amadyetsa makamaka nsomba ndi tizilombo. Zomera zimadyedwanso, koma ili ndi gawo laling'ono la zakudya. Amadziwika chifukwa chosakhuta - mbalame, njoka, anyani, akamba, makoswe, adapeza zonse m'mimba mwake.
Amadya zakudya zamtundu uliwonse zam'madzi. Ma bloodworms, tubifex, koretra, nsomba zazing'ono, nkhanu, nyama ya mussel, mtima ndi zina zambiri.
Nthawi zina amadyanso mapiritsi kapena zakudya zina zopangira. Koma kuzinthu zina zonse, Arowans amakonda nsomba zamoyo, zomwe zimameza pouluka.
Ndi kupirira kwina, atha kuphunzitsidwa kudyetsa nsomba yaiwisi, nkhanu kapena chakudya china chanyama.

Kwa nsomba zazikulu pamafunika kuchuluka kwa malita 800-1000. Zodzikongoletsera ndi zomera sizimusamala, koma aquarium iyenera kuphimbidwa, chifukwa imalumpha bwino.
Arow amakonda kutentha (24 - 30.0 ° C), madzi oyenda pang'onopang'ono ndi ph: 6.5-7.0 ndi 8-12 dGH. Kuyeretsa kwa madzi ndikofunikira kwambiri, chifukwa kusunga ndikofunikira kugwiritsa ntchito fyuluta yakunja yamphamvu, yomwe ikuyenda bwino yomwe imagawidwa pansi.
Kusintha kwa nthaka nthawi zonse ndi kupopera ndi kofunikanso.
Nsombazo zimakhala zamanyazi, ndipo nthawi zambiri zimatha kudumpha kuchokera pakuphatikizidwa mwadzidzidzi kwa kuyatsa. Ndi bwino kugwiritsa ntchito nyali zomwe zimawala pang'onopang'ono ndipo sizikuwopsyeza nsomba.
Ngakhale
Zachidziwikire kuti nsomba sizomwe zimapezeka m'madzi ambiri. Ma Juveniles amatha kusungidwa limodzi ndi nsomba zina. Koma arowan okhwima mwauzimu adya nsomba zonse zomwe angathe kumeza.
