Alamomin da ake buƙata:

• zafin jiki daga digiri 20;
• matsakaicin taurin ruwa.

Wani fasali na musamman na katantanwa na jiki (musamman matasa) shine ikonsu na samar da zaren bakin ciki mai ɗaki. Wani katantanwa na akwatin kifaye yana haɗa shi zuwa wurare daban-daban - duwatsu, snags ko shuke-shuke, kuma yana kaiwa zuwa saman, manne da ganye ko gilashi.

Some aquarium lovers will tell you that Fiza snails are hardly desirable inhabitants of the underwater economy.

Da farko, Suna ciyar da ba kawai a kan lalata dabbobi da ragowar tsire-tsire ba, amma kuma suna da ban sha'awa ga algae, sun ɗanɗana wanda, koyaushe suna barin ƙananan ramuka.

Na biyu, fiza is a hermaphrodite, and even being in a single copy in an aquarium, it easily reproduces, filling the space.

Abu na uku, moving through the expanses of water, the phys can unwittingly destroy the fragile shell of the eggs, swept out by the fish living nearby.

But there are also positive features of the nature of these mollusks.

Tsawon rayuwa na phys shine watanni 11-14. Matasa sun fi wayar hannu kuma an bambanta su da ikon ƙirƙirar zaren bakin ciki na gamsai da shimfiɗa su daga ƙasa zuwa sama, suna haɗa iyakar zuwa saman algae. A kan waɗannan igiyoyin, waɗanda ke dawwama har zuwa kwanaki 20, physic yana motsawa zuwa saman ruwa kuma ya dawo don cika jiki da iska.

Mollusk yana haifuwa ta hanyar sanya ƙwai akan ganyen algae (daga guda 10 zuwa 20 a lokaci ɗaya). Bayan makonni 2-4, sabbin katantanwa da yawa suna fitowa daga cikinsu.

A wannan yanayin, zaka iya kiran taimakon kifi na iyalin cichlid, alal misali, Pseudotropheus Lombardo. Suna iya cin manya katantanwa. Catfish na iya lalata ƙwai da matasa daidaikun mutane. Brocade glyptopericht ko Ancistrus talakawa.

Ta hanyar dabi'ar su, katantanwa na jinsin Physa ba su da fa'ida kuma ba sa buƙatar kulawa ta musamman. Tare da zaɓin da ya dace na mazaunan aquarium, za su iya zama ainihin kayan ado na tafki!

Amma ko da a gaban abinci, ilimin kimiya na kifin kifaye yana yiwuwa ya so cin abinci a kan tsire-tsire a cikin akwatin kifaye. Yana haifar da mummunar lalacewa ga bayyanar su na ado ta hanyar cin ramukan ganye.
