Pristella Ridley (Latin Pristella maxillaris) ndi haracin yaying'ono yokongola. Thupi lake la siliva limakhala lopepuka, ndipo zipsepse zake zakumaso ndi kumatako zimajambula utoto wachikaso, chakuda ndi choyera.
Uku ndikusankha kwabwino kwam'madzi am'madzi, ndiwodzichepetsa kwambiri ndipo kumalekerera bwino madzi amitundu yosiyanasiyana.
Izi ndichifukwa choti m'chilengedwe amakhala m'madzi amchere komanso amchere. Pristella amatha kukhala m'madzi ovuta kwambiri, ngakhale amakonda madzi ofewa.
Nthaka yamdima ndi kuwala kofewa kudzawulula kukongola konse kwa nsombazo, pomwe kuyatsa kowala ndi madzi olimba, m'malo mwake, kuzipangitsa kukhala zotuwa komanso zopanda mawu. Zikuwoneka bwino makamaka m'madzi okhala ndi madzi ambiri.
Pristella ndi wokangalika, wokonda kucheza, wamtendere kwambiri, wosavuta kubereketsa.
Kukhala m'chilengedwe
Pristella wa Ridley adafotokozedwa koyamba mu 1894 ndi Ulrey. Amakhala ku South America: Venezuela, British Guyana, m'munsi mwa Amazon, Orinoco, mitsinje ya Guiana.
Amakhala m'madzi agombe, omwe nthawi zambiri amakhala ndi madzi amchere. M'nyengo yadzuwa, nsomba zimakhala m'madzi oyera komanso m'mitsinje, ndipo nyengo yamvula ikayamba, imasamukira kumadera osefukira ndiudzu.
Amakhala m'magulu, m'malo okhala ndi zomera zambiri, komwe amadyetsa tizilombo tosiyanasiyana.
Kufotokozera
Kapangidwe ka thupi kofanana ndi ma tetra. Kukula kwake sikokwanira kwambiri, mpaka 4.5 cm, ndipo kumatha kukhala zaka 4-5.
Mtundu wa thupi ndi wachikasu, chakumaso ndi chakumapeto chimakhala ndi mawanga, ndipo kumapeto kwake ndi kofiira.
Palinso albino wokhala ndi maso ofiira komanso thupi lotayika, koma pamsika sapezeka.
Zovuta pakukhutira
Nsomba zosadzichepetsa komanso zolimba. Amaweta kwambiri, amapezeka pamsika ndipo amasinthidwa moyenera ndimikhalidwe yakomweko.
Ndikokwanira kuwona momwe zinthu zilili mu aquarium kuti zimveke bwino.
Kudyetsa
Omnivores, pristella amadya zakudya zamtundu uliwonse, zachisanu kapena zopangira. Amatha kudyetsedwa ndi ma flakes apamwamba, ndipo ma bloodworms ndi brine shrimp amatha kupatsidwa nthawi ndi nthawi, kuti akhale ndi chakudya chokwanira.
Chonde dziwani kuti ma tetra ali ndi kamwa yaying'ono ndipo muyenera kusankha chakudya chochepa.
Kusunga mu aquarium
Kusukulu, kuti nsomba zizikhala zomasuka, muyenera kuziika pagulu la zidutswa zisanu ndi chimodzi, mumchere wokhala ndi matani 50-70. Ndi bwino kubzala m'mphepete mwa nyanja mozungulira m'mphepete mwake, ndi malo omasuka pakati pakusambira.
Pristells amakonda kuyenda pang'ono komwe kumatha kupangidwa pogwiritsa ntchito zosefera zakunja kapena zamkati. Popeza amafunikira madzi oyera kuti aziwasunga, ndibwino kugwiritsa ntchito akunja. Ndipo sinthani madzi pafupipafupi kuti mupewe kudzikundikira.
Kuwala kwa aquarium kuyenera kukhala kofiyira, kotayika. Magawo amadzi: kutentha 23-28, ph: 6.0-8.0, 2 - 30 dGH.
Monga lamulo, nyama zolusa sizimalekerera madzi amchere bwino, koma pankhani ya pristella, izi ndizosiyana.
Ndiye yekhayo haracin yemwe amakhala m'chilengedwe mosiyanasiyana, kuphatikiza madzi amchere, okhala ndi mchere wambiri.
Komabe si nsomba yam'nyanja ndipo singalekerere mchere wambiri wamadzi. Mukasunga mumadzi amchere pang'ono, ndiye osaposa 1.0002, popeza atha kufa kwambiri.
Ngakhale
Wamtendere ndipo amakhala bwino ndi nsomba zosadya nyama iliyonse. Zothandiza pamadzi ogawidwa omwe ali ndi mitundu yofananira.
Amakhala m'magulu, anthu osachepera ndi ochokera 6. Ali amanyazi kwambiri, chifukwa chake sikoyenera kuyika nyanja pamalo otseguka.
Yogwirizana kwambiri ndi mitundu yofanana: erythrozonus, black neon, taracatum, ancistrus, lalius.
Kusiyana kogonana
Amuna ndi ochepa, okongola kuposa akazi. Mimba ya akazi ndi yayikulu, yozungulira, ndipo iwonso ndi okulirapo.
Kuswana
Kuswana, kubereka ndi kosavuta, vuto lalikulu ndikupeza awiri. Wamwamuna nthawi zambiri amasankha yemwe angakhale mnzake ndipo amakana kubala.
Aquarium yapadera, yowala pang'ono, ndibwino kuti mutseke kwathunthu galasi lakumaso.
Muyenera kuwonjezera zomera ndi masamba ang'onoang'ono, monga moss wa ku Javanese, pomwe nsomba ziziikira mazira. Kapena, tsekani pansi pa aquarium ndi ukonde, popeza ma tetra amatha kudya mazira awo.
Maselowo ayenera kukhala okulira kuti mazira adutsenso.
Awiri amabzalidwa mu aquarium yapadera madzulo. Kuswana kumayamba m'mawa mwake. Pofuna kuti opanga asadye caviar, ndibwino kugwiritsa ntchito ukonde, kapena kubzala nthawi yomweyo atangobereka.
Mphutsi zidzaswa m'maola 24-36, ndipo mwachangu amasambira masiku 3-4.
Kuyambira pano, muyenera kuyamba kumudyetsa, chakudya choyambirira ndi infusorium, kapena chakudya chamtunduwu, pamene chikukula, mutha kusamutsa mwachangu kukasamba shrimp nauplii.
