Muzvisikwa, nzvimbo yekugara inotangira kubva kuGuatemala (Central America), muUnited States yose uye kumatunhu ekumaodzanyemba kweCanada. Inoitika mumahombekombe enzizi, madziva mumvura isina kudzika, munzvimbo dzine machakwi. Dzinokura pasi pemvura uye pavhu rakanyorova (rakanyorova), dzichiita masumbu akaonda. Kana iri mumhoteredzo yemvura uye apo nhungirwa dzinosvika pamusoro, maruva eyero ane maruva matanhatu anooneka. Nekuda kwechimiro chemaruva muzvinyorwa zvechiRungu, chirimwa ichi chinodaidzwa kuti "Water stargrass" - Water star grass.

Kana yanyura, chirimwa ichi chinoumba dzinde dzakati twasu, dzine matavi akanyanya kukura kusvika kumusoro chaiko, kwadzinozokura pasi pemvura, dzichigadzira “makapeti” akaonda. Kureba kwechirimwa kunogona kusvika kudarika mita. Panyika, madzinde haakure akamira, asi anopararira pasi. Mashizha acho akareba (5-12 cm) uye nhete (anenge 0.4 cm), chiedza chegirini kana chakacheneruka muruvara. Mashizha anowanikwa pane imwe node yewhorl. Maruva anoonekwa pamuseve paurefu hwe 3-4 cm kubva pamusoro pemvura. Nekuda kwehukuru hwayo, inoshanda chete muhombe aquariums.

Heteranther inonyunyuta haina kuzvikudza, inokwanisa kukura mumvura inotonhorera, kusanganisira madziva akazaruka, mune zvakasiyana-siyana zve hydrochemical parameters. Kudzura midzi kunoda ivhu rejecha kana kuti rakatsetseka. Yakakosha aquarium ivhu isarudzo yakanaka, kunyangwe isingadiwe kune iyi mhando. Inofarira chiedza chepakati kusvika pakakwirira. Zvinocherechedzwa kuti maruva anoonekwa chete muchiedza chakajeka.
