Tetra Amanda (lat. Hyphessobrycon amandae) ndi nsomba yaying'ono yamadzi oyera ochokera kubanja la haracin (Characidae). Amakhala mu beseni la Mtsinje wa Araguaya, ku Brazil ndipo adapezeka zaka 15 zapitazo. Ndipo dzinali lidaperekedwa polemekeza amayi a Heiko Bleher, a Amanda Bleher.
Kukhala m'chilengedwe
Amakhala mumtsinje wa Araguaya ndi mitsinje yake, Rio das Mortes ndi Meya wa Braco, ngakhale sizinatheke kudziwa malo okhala Amanda tetra.
Ambiri, pali zambiri zokhudza chilengedwe, koma amakhulupirira kuti amakonda kukhala mumtsinje, nyanja ndi mayiwe kuposa momwe mumakhalira mtsinjewo.
Chodziwika bwino cha biotope ya mitsinje yotereyi ndi masamba ambiri omwe agwa pansi, nthambi, komanso madzi ofewa, acidic.
Kufotokozera
Thupi limakhala lofanana ndi ma tetra onse, koma kutalika kwake kumangokhala masentimita 2. Mtundu wanthawi zonse wa thupi ndi lalanje kapena wofiira - wofiira, diso la irbis lilinso lalanje, lokhala ndi mwana wakuda.
Kutalika kwa moyo mpaka zaka ziwiri.
Zokhutira
Iyenera kusungidwa mumchere wokhala ndi zomera zambiri komanso makamaka mdima. Zomera zoyandama ziyenera kuikidwa pamwamba pamadzi, masamba owuma ayenera kuikidwa pansi, ndipo aquarium iyenera kukongoletsedwa ndi mitengo yolowerera.
Amakhala nthawi yayitali pakati pa nkhalango, amathanso kubalalamo, ndipo ngati mulibe nsomba ina mu aquarium, ndiye kuti mwachangu kumakula, chifukwa mabakiteriya omwe amawononga masamba owuma pansi amakhala chakudya choyambira.
Tetra Amanda amakonda madzi okhala ndi acidity pafupifupi pH 6.6, ndipo ngakhale amakhala m'madzi ofewa kwambiri m'chilengedwe, amasinthasintha bwino kuzizindikiro zina (5-17 dGH).
Kutentha kololedwa kusunga ndi 23-29 C. Ayenera kusungidwa m'gulu, osachepera zidutswa 4-6 kuti azisambira limodzi.
Amatha kupanga sukulu ndi ma tetra ena, mwachitsanzo, ndi ana, koma pamaso pa nsomba zazikulu kwambiri, amakhala ndi nkhawa.
Ma tetra a Amanda amakhala ndikudya m'mbali yamadzi, ndipo musatenge chakudya kuchokera pansi. Chifukwa chake ndibwino kuti tizikhala nawo tinsomba tating'onoting'ono, monga njira yapa pygmy, kuti azidya zotsalira za chakudya.
Kudyetsa
Mwachilengedwe, amadya tizilombo tating'onoting'ono ndi zooplankton, ndipo mu aquarium amadya chakudya chopangira komanso chamoyo. Chinthu chachikulu ndi chakuti iwo ali ochepa.
Ngakhale
Mtendere mwamtendere, koma sungasungidwe ndi nsomba zazikulu komanso zosakhazikika, osatinso nyama zowononga. Mu aquarium yonse, ndibwino kukhala ndi kukula kofanana, haracin yamtendere, makonde osaya kapena nsomba zomwe zimakhala pafupi ndi madzi, monga mphete.
Zimagwirizana bwino ndi apistograms, chifukwa zimakhala pakati pamadzi ndipo sizisaka mwachangu. Chabwino, ma rassors, neon, ma micro rasboros adzakhala oyandikana nawo kwambiri.
Muyenera kugula nsomba zosachepera 6-10, chifukwa pagulu samakhala owopsa ndipo amawonetsa chidwi.
Kusiyana kogonana
Amuna ndi owala kwambiri, pomwe akazi, monga ma tetra onse, amakhala ndi mimba yokwanira komanso yokwanira.
Kuswana
Mukasungidwa mumtsinje wosungika komanso m'malo abwino, ma tetras a Amanda amatha kuberekana popanda kuthandizidwa ndi anthu.
Akazi amaikira mazira pazitsamba zazing'ono, ndipo mwachangu amadyetsa infusoria omwe amakhala ndi masamba owuma a mitengo yomwe ili pansi.
Kuti muwonjezere mwayi wopambana, acidity yamadzi iyenera kukhala pH 5.5 - 6.5, yofewa, komanso yowunikira pang'ono.
Ndikofunika kudyetsa nsomba zochuluka komanso mosiyanasiyana ndi chakudya chokhazikika kwamasabata awiri.
