Madziwo akuyenera kuphimbidwa kapena akuyandama zomera zoyandama pamwamba.
Opanga amafunika kudyetsedwa chakudya chamoyo asanabzalidwe kuti abereke. Amatha kubereka m'gulu, 5-6 nsomba za amuna ndi akazi zidzakhala zokwanira, komabe, ndipo zimaswana bwino awiriawiri.
Ndikofunika kuti apange opanga m'malo osiyanasiyana am'madzi, ndikudyetsa kwakanthawi kwakanthawi. Kenako muwayike m'malo opumira madzulo, madzi omwe ayenera kutentha pang'ono.
Kuswana kumayamba m'mawa kwambiri.
Akazi amaikira mazira pazomera, koma nsomba zimatha kuzidya, ndipo ngakhale atapeza mpata pang'ono amafunika kuti zibzalidwe. Mphutsi zimaswa mu maola 24-36, ndipo pambuyo pa masiku ena atatu mwachangu zimayamba kusambira.
Masiku oyamba mwachangu amadyetsedwa ndi zakudya zazing'ono, monga ma ciliili ndi madzi obiriwira, akamakula, amapatsa microworm ndikusamba shrimp nauplii.
Caviar ndi mwachangu zimakhala zosazindikira m'masiku oyamba amoyo, chifukwa chake aquarium iyenera kuchotsedwa padzuwa ndikusungidwa pamalo okwanira.
