Muchigadziro, zvinodikanwa kupa nzvimbo dzekugara mumhando yematanda emiti. Nekudaro, zvinofanirwa kurangarirwa kuti Metinnis akajairwa anowanzo kukuvadza nzvimbo dzakapfava dzezvirimwa, saka zvinokurudzirwa kushandisa mhando dzinokura nekukurumidza dzine mashizha akaomarara, kana kuzviganhurira kune zvinomera zvekugadzira. Kupenya kwakadzikira.

Metinnis akajairwa anogara kunyanya pakati nepamusoro pemvura, saka hove dzinogara padyo nepasi dzichava shamwari dzakanaka. Somuenzaniso, catfish kubva Plecostomus uye Bronyakovs.
Kubereka / kubereka
Kuberekera mbeu kunowanzoitika munzvimbo dzakapfava dzine acidic mvura inosvika 28°C. Nekutanga kwemwaka wekubereka, varume vanowana mithunzi yakasviba, uye hutsvuku hunoonekwa munzvimbo yechipfuva. Mushure mekupfimbana kwenguva pfupi, hove dzinokandira makumi akawanda emazai, dzichiamwaya pamusoro pevhu pasina kuita clutch.
Sezvo mutemo, hove dzakura hadzidyi mazai avo. Nekudaro, vamwe vagari vemu aquarium vanovafarira nekunakidzwa. Kuti uchengetedze vana, zvinodikanwa kuendesa mazai kune imwe tangi. Iyo fry inooneka mushure memazuva matatu. Pakutanga, vanodya pane zvakasara zveyolk sac yavo, uye vobva vatanga kushambira vakasununguka vachitsvaka zvokudya. Kudyisa nehunyanzvi hwehupfu hwehupfu, kumiswa kwekudyisa vechidiki aquarium hove.
Zvirwere zvehove
Chikonzero chikuru chezvirwere zvakawanda ndezvemukati mune zvisiri izvo. Muchiitiko chezviratidzo zvekutanga, zvakakosha kutarisa hutano uye hydrochemical kuumbwa kwemvura, kana zvichidiwa, kuunza zviratidzo zvose kune zvakajairika uye chete wozoenderera mberi nekurapa.
