Erythrozonus hemigrammus kapena firefly (Latin Hemigrammus erythrozonus gracilis) ndi nsomba yaying'ono yam'madzi yochokera kumtundu wa tetra, yomwe ili ndi mzere wokongola mthupi.
Sukulu ya nsombazi imatha kudabwitsa ngakhale akatswiri odziwa zamadzi. Ndikukula, mtundu wa thupi la nsombayo umayamba kuwonekera ndipo umakhala wokongola.
Haracin iyi ndi imodzi mwamisewu yamtendere kwambiri yam'madzi. Monga ma tetra ena, erythrozonus imamva bwino pagulu, kuyambira anthu 6-7 komanso kupitilira apo.
Amawoneka bwino kwambiri mumtambo wa aquarium, wokhala ndi nsomba zazing'ono komanso zamtendere.
Kukhala m'chilengedwe
Nsombazo zidafotokozedwa koyamba ndi Dubrin mu 1909. Amakhala ku South America, mumtsinje wa Essequibo. Essequibo ndiye mtsinje waukulu kwambiri ku Gayane ndipo biotopes zambiri zimapezeka kutalika kwake konse.
Nthawi zambiri amapezeka mumtsinje wa mtsinjewu wokhala ndi nkhalango zambiri. Madzi m'mitsinje yaying'onoyi nthawi zambiri amakhala ofiira kuchokera kumasamba owola ndipo amakhala ndi acidic kwambiri.
Amakhala m'magulu ndipo amadya tizilombo ndi mphutsi zawo.
Pakadali pano, ndizosatheka kupeza nsomba zomwe zagwidwa m'chilengedwe zikugulitsidwa. Nsomba zonse zimasinthidwa kwanuko.
Kufotokozera
Erythrozonus ndi amodzi mwa ma tetra ang'ono ndi ocheperako. Imakula mpaka 4 cm kutalika, ndipo imakhala mumchere ya aquarium pafupifupi zaka 3-4.
Imafanana pang'ono ndi neon wakuda, makamaka mzere wake wowala, koma iyi ndi nsomba ina. Sikovuta kusiyanitsa, neon yakuda imakhala ndi thupi lakuda mofananamo, ndipo erythrozonus ndiyowonekera.
Zovuta pakukhutira
Ngati aquarium ndiyabwino komanso yoyambitsidwa bwino, sizikhala zovuta kukhala ndi erythrozonus ngakhale kwa oyamba kumene.
Amakhala m'malo osiyanasiyana ndipo amaberekanso mophweka. Zimakhala zoyenera kwa iwo omwe akufuna kuyesa kusodza nsomba koyamba.
Sizovuta kwenikweni kusamalira, koma amadya mitundu yonse yazakudya. Ndi bwino kuwadyetsa kangapo patsiku, ndi chakudya chochepa, popeza nsombazo sizowopsa.
Kudyetsa
Popeza ndi omnivores, mosangalala amadya mitundu yonse yazakudya zokhazokha, zachisanu kapena zopangira mu aquarium. Sikovuta kuwadyetsa mu aquarium, pafupifupi mitundu yonse yazakudya ndi zabwino.
Ma flakes, pellets, chakudya chamoyo komanso chachisanu, chinthu chachikulu ndichakuti nsomba zimatha kuzimeza. Ndi bwino kudyetsa 2-3 patsiku, pang'ono, popeza nsomba sizidya chakudya chomwe chagwera pansi.
Kusunga mu aquarium
Ma erythrozones amasungidwa bwino mu gulu la nsomba za 6-7, chifukwa chake amafunikira aquarium yamalita 60 kapena kupitilira apo. Amanyalanyaza kwambiri mndende, chinthu chachikulu ndikuti zikhalidwe ndizomveka komanso zopanda malire.
Amakhala osangalala m'madzi ofewa komanso acidic, koma nsomba zomwe zimagulitsidwa m'dera lanu zasinthiratu kukhala ndi moyo mosiyanasiyana.
Kuunika kosamalira ma tetra aliwonse kuyenera kufalikira ndikuchepa, ma erythrozones nawonso. Njira yosavuta yokwaniritsira izi ndikuyika mbewu zoyandama pamwamba pa aquarium.
Chofunika kwambiri ndi kuyeretsa kwa madzi ndi otsika kwambiri a ammonia ndi nitrate. Kuti muchite izi, muyenera kusintha gawo lamadzi sabata iliyonse ndikugwiritsa ntchito sefa mu aquarium.
Magawo amadzi okhutira: kutentha 23-28C, ph: 5.8-7.5, 2 - 15 dGH.
Ndibwino kuti mupange biotope yachilengedwe mu aquarium. Nthaka pansi pake ndi mchenga wamtsinje wakuda, wokhala ndi mitengo yolowerera ndi miyala yaying'ono ngati zokongoletsa. Muthanso kuyika masamba pansi, omwe amapatsa madzi utoto wofiirira.
Mulibe mbewu zambiri m'mitsinje momwe erythrozonus amakhala, chifukwa chake safuna nkhalango zobiriwira.
Kusiyana kogonana
Zazimayi ndizokulirapo, zodzaza kuposa amuna, zomwe zimakhala zokongola komanso zowala kwambiri.
Kuswana
Mbalame za mbalamezi zimakhala zosavuta kubereka, koma kwa oyamba kumene zidzakhala zopindulitsa.
Pofuna kuswana, konzani aquarium yosiyana ndi madzi ofewa osapitirira 6 dGH ndi pH ya 5.5 mpaka 7.0.
Tikulimbikitsidwa kugwiritsa ntchito peat kuti mupeze magawo amenewo.
Kutentha kwamadzi kumakweza mpaka 25-28 C.
Kubala kuyenera kukhala kowala pang'ono, kuwala kwachilengedwe kwakukulu. Kuchokera ku zomera, moss wa ku Javanese kapena zomera zina zomwe zili ndi masamba ang'onoang'ono zimagwiritsidwa ntchito.
Opanga amawadyetsa amoyo mpaka kasanu patsiku. Zofunikira zosiyanasiyana, ma bloodworms, brine shrimp, tubule, ndi zina zambiri.
Pamene banjali likukonzekera kubereka, mwamuna amayamba kuthamangitsa mkaziyo, kuluma zipsepse zake ndikunjenjemera pamaso pake ndi thupi lake lonse.
Pakapita nthawi, chibwenzi chimasanduka kuberekana, pomwe nsombayo imatembenukira kumbuyo ndikutulutsa mazira ndi mkaka. Nthawi zambiri kuchuluka kwa mazira kumayambira 100 mpaka 150.
Makolo sasamalira caviar ndipo amatha kudya, motero amafunika kubzala nthawi yomweyo. Akatswiri ena am'madzi amagwiritsa ntchito khoka lotetezedwa lomwe limayikidwa pansi.
Caviar ndiwopepuka kwambiri ndipo tikulimbikitsidwa kuti tiphimbe nyanja. Pafupifupi tsiku limodzi, mbozi imaswa, ndipo mwachangu amasambira masiku ena atatu.
Patatha milungu iwiri, mwachangu amasintha siliva koyamba, ndipo pambuyo pa masabata ena atatu amakhala ndi mzere. Poyamba, imafunika kudyetsedwa ndi ma ciliates ndi nematode, ndipo pakapita kanthawi iyenera kusamutsidwa kupita ku Artemia nauplii.
