Siziwononga zomera, koma, mwachilengedwe, zomera sizipezeka m'malo okhala nsomba.
Amawoneka achilengedwe momwe mungathere mu aquarium yopanda zomera, ndi miyala yayikulu m'mphepete ndi yaying'ono pakati ndi nthaka yakuda. Kuunikako ndikuchepa, mwina ndi nyali zofiira kapena zabuluu.
Nsomba zimagwiritsa ntchito mzere wazotsatira kuti ziziyenda mlengalenga, komanso kuti zizigwera pazinthu siziyenera kuopedwa.
Komabe, ichi si chifukwa cholepheretsa aquarium ndi zokongoletsera, kusiya malo okwanira osambira.
Madzi amchere okhala ndi malita 200 kapena kupitilira apo ndi ofunikira, ndi kutentha kwa madzi kwa 20 - 25 ° C, pH: 6.5 - 8.0, kuuma 90 - 447 ppm.
Kudyetsa
Chakudya chamoyo komanso chazizira - tubifex, ma bloodworms, brine shrimp, daphnia.
Ngakhale
Wopanda ulemu komanso wamtendere, nsomba zakhungu zam'madzi ndizoyenera kwa oyamba kumene, chifukwa zimayenda bwino m'madzi okhala nawo.
Nthawi zina amatsina zipsepse za anansi awo akamadyetsa, koma izi zimakhudzana kwambiri ndi kuyeserera koyenera kuposa kukwiya.
Sangatchedwe zapamwamba komanso zowala, koma nsomba zakhungu zimawoneka zowoneka bwino komanso zosangalatsa pagulu, motero tikulimbikitsidwa kuti tisunge anthu osachepera 4-5.
Kusiyana kogonana
Mkazi ndi wonenepa kwambiri, wokhala ndi mimba yayikulu, yokhotakhota. Amuna, chimbudzi chakumapeto chimakhala chochepa pang'ono, koma chachikazi chimakhala chowongoka.
