Corridoras nanus (lat. Corydoras nanus) ndi katchi yaying'ono yamtundu umodzi mwazinthu zodziwika bwino kwambiri za aquarium catfish - makonde.
Zing'onozing'ono, zoyenda, zowala, zimawoneka zogulitsa posachedwa, koma nthawi yomweyo zidapambana mitima ya akatswiri.
Kukhala m'chilengedwe
Dziko lakwawo ndi catfish iyi ndi South America, amakhala mumitsinje ya Suriname ndi Maroni ku Suriname komanso mumtsinje wa Irakubo ku French Guiana. Corridoras nanus amakhala m'mitsinje ndi mumtsinje womwe ulipo pang'ono, kuyambira theka la mita mpaka mita zitatu m'lifupi, osaya (20 mpaka 50 cm), wokhala ndi mchenga ndi silty pansi ndipo umawalitsira dzuwa pansi.
Amakhala nthawi yayitali akufunafuna chakudya, kukumba mumchenga ndi matope. Mwachilengedwe, nanus amakhala m'magulu akulu, ndipo amayeneranso kusungidwa mu aquarium, osachepera 6 anthu.
Kufotokozera
Khonde limakula ndi nanus mpaka 4.5 cm m'litali, kenako akazi, amuna amakhala ocheperako. Kutalika kwa moyo kuli pafupifupi zaka zitatu.
Thupi ndi silvery, ndi mikwingwirima yakuda yothamanga kuyambira kumutu mpaka mchira.
Mtundu wamimba ndi wotuwa.
Mtundu uwu umathandiza kuti nsombazi zizidzibisa kumbuyo kwa pansi, ndikubisala kuzilombo.
Zokhutira
Mwachilengedwe, nsombazi zimakhala m'malo otentha, momwe kutentha kwamadzi kumayambira 22 mpaka 26 ° C, pH 6.0 - 8.0 ndi kuuma 2 - 25 dGH.
Amasintha bwino m'madzi okhala m'madzi ndipo nthawi zambiri amakhala m'malo osiyanasiyana.
Thanki ya nanus iyenera kukhala ndi zomera zambiri, nthaka yabwino (mchenga kapena miyala), ndi kuwala kofalitsa. Ndinafika pozindikira kuti amafunikira aquarium yaying'ono komanso oyandikana nawo ochepa.
Kuwala koteroko kumatha kupangidwa pogwiritsa ntchito zomera zoyandama pamwamba, ndikofunikanso kuwonjezera mitengo yambiri, miyala ndi malo ena obisalamo.
Amakonda kubisala m'nkhalango zowirira, choncho ndibwino kuti mukhale ndi zomera zambiri m'mphepete mwa nyanja.
Monga makonde onse, nanus amamva bwino pagulu, kuchuluka kochepa kosungika bwino, kuchokera kwa anthu 6.
Mosiyana ndi makonde ena, nanus amakhala pakatikati pamadzi ndikudyetsa pamenepo.
Kudyetsa
Mwachilengedwe, imadyetsa ma benthos, mbozi za tizilombo, nyongolotsi ndi tizilombo tina ta m'madzi. M'nyanja yamchere, ma nanuses ndi odzichepetsa ndipo amafunitsitsa kudya mitundu yonse yamoyo, yachisanu ndi yokumba.
Vuto lodyetsa ndikuchepa kwawo komanso momwe amadyetsera. Ngati muli ndi nsomba zina zambiri, ndiye kuti chakudya chonse chidzadyedwa ngakhale mkatikati mwa madzi ndipo nanus adzapeza zinyenyeswazi chabe.
Dyetsani mowolowa manja kapena perekani ma pellets apadera. Kapenanso, mutha kudyetsa musanazime kapena mutazimitsa magetsi.
Kusiyana kogonana
Ndikosavuta kusiyanitsa mkazi ndi wamwamuna wa nanus. Monga makonde onse, akazi ndi okulirapo, ali ndi mimba yotakata, yomwe imawonekera kwambiri mukawayang'ana kuchokera pamwamba.
Ngakhale
Komabe, nsomba yosavulaza, catfish yomweyi imatha kuvutika ndi mitundu yayikulu komanso yolusa, chifukwa chake muyenera kuyisunga ndi mitundu yofanana komanso bata.
