Habitat

Nsombazi zimakhala mumtsinje wa Amazon (South America) m'dera la Paraguay ndi Brazil. Amakhala m'magulu m'masungidwe odzaza kwambiri, amakonda kwambiri zakudya zamasamba, koma amathanso kudya mphutsi ndi tizilombo tating'onoting'ono.

Kufotokozera

Silver Metinnis ndi nsomba yaikulu yokhala ndi thupi looneka ngati disiki lopanikizidwa kwambiri pambali. Utoto wake ndi wasiliva, nthawi zina wokhala ndi utoto wobiriwira pakuwunikira kwina, utoto wofiyira umawonekera pamapiko amphuno. Ali ndi timadontho tating'ono, timadontho tating'ono m'mbali.

Food

Maziko a zakudya ndi chakudya ndi mkulu zili zomera zigawo zikuluzikulu. Ndi zofunika kupereka chakudya chapadera mu mawonekedwe a flakes kapena granules. Monga chowonjezera, mutha kupereka zinthu zama protein (bloodworm, brine shrimp, etc.). Nthawi zina, imatha kudya nsomba zing'onozing'ono, zokazinga.

Kusamalira ndi kusamalira

Aquarium yayikulu ndiyofunikira, yokhala ndi zomera zambiri, koma iyenera kukhala m'mphepete mwa makoma a aquarium kuti isiya malo okwanira osambira. Zomera ziyenera kugwiritsidwa ntchito mwachisawawa kapena kukhala ndi moyo wokulirapo. Nthaka ndi mchenga wokhala ndi zinthu zingapo zokongoletsera zochepa: matabwa, mizu, driftwood.

Silver Dollar imafuna madzi apamwamba kwambiri, kotero kuti fyuluta yogwira ntchito kwambiri imatsimikizira kusunga bwino. Chowotchacho chimalimbikitsidwa kuchokera ku zipangizo zosasweka, nsomba zimakhala zogwira ntchito kwambiri ndipo zimatha kuthyola mwangozi magalasi kapena kuwang'amba. Samalirani kukhazikika kotetezeka kwa zida zapansi pamadzi.

Makhalidwe a anthu

Nsomba zamtendere komanso zogwira ntchito, koma siziyenera kusungidwa pamodzi ndi mitundu yaying'ono, zidzawukiridwa, ndipo oyandikana nawo ang'onoang'ono adzalanda msanga. Kuweta gulu la anthu osachepera anayi.

Kuswana / kuswana

Imodzi mwa mitundu yochepa ya characin yomwe siidya ana ake, kotero kuti thanki yosiyana sikufunika kuswana, pokhapokha ngati palibe mitundu ina ya nsomba mu aquarium.

Miwiritsani zomera zingapo zoyandama mu aquarium, ngati sizinalipo kale, kumera kumachitika m'magulu awa. Yaikazi imayikira mazira 2000, omwe amagwera pansi, ndipo mwachangu amawonekera pambuyo pa masiku atatu. Amathamangira kumtunda ndipo amakhala pamenepo mpaka atakula, mitengo yamitengo yoyandama imakhala chitetezo ngati mwadzidzidzi makolowo aganiza zodyera nazo. Dyetsani microfeed.
