I-Erythrozonus hemigrammus noma i-tetra firefly (isiLatin Hemigrammus erythrozonus gracilis) yizinhlanzi ezincane zasemanzini ezivela kuhlobo lwe-tetra, ezinomugqa omuhle okhazimulayo emzimbeni.
Isikole salezi zinhlanzi singamangala ngisho nomuntu osebenza emanzini futhi onolwazi kakhulu. Ngokukhula, umbala womzimba wenhlanzi uya ubonakala kakhulu futhi uba muhle.
Le haracin ingenye yezinhlanzi ezinokuthula kakhulu zasemanzini. Njengamanye ama-tetra, i-erythrozonus izwa kamnandi kuphela emhlambini, kusuka kubantu abayi-6-7 nangaphezulu.
Zibukeka kahle kakhulu ku-aquarium eyabiwe, enezinhlanzi ezincane nezinokuthula.
Ukuphila emvelweni
Inhlanzi yachazwa okokuqala nguDubrin ngo-1909. Uhlala eSouth America, eMfuleni i-Essequibo. I-Essequibo ingumfula omkhulu kunayo yonke eGayane futhi ama-biotopes amaningi ahlukene atholakala kubude bawo bonke.
Esikhathini esiningi zitholakala emithanjeni yomfula egcwele ihlathi. Amanzi kule mifula emincane ngokuvamile anombala onsundu ovela emaqabungeni abolile futhi ane-asidi kakhulu.
Zihlala emihlambini futhi zidla izinambuzane kanye nezibungu zazo.
Okwamanje, akunakwenzeka ukuthola izinhlanzi ezibanjwe emvelweni ngokuthengisa. Zonke izinhlanzi zikhiqizwa endaweni.
Incazelo
I-Erythrozonus ingenye yama-tetra amancane futhi amancane. Ikhula ize ifike ku-4 cm ubude, futhi ihlala e-aquarium cishe iminyaka engu-3-4.
Ifana ngandlela thile neon emnyama, ikakhulukazi umucu wayo okhazimulayo, kepha nakanjani lolu uhlobo oluhlukile lwezinhlanzi. Akunzima ukuwahlukanisa, i-neon emnyama inomzimba omnyama ofanayo, kanti i-erythrozonus iyaguquguquka.
Kunzima kokuqukethwe
Uma i-aquarium ilinganiselwe kahle futhi iqalwe kahle, ngeke kube nzima ukuqukatha i-erythrozonus ngisho nakwisiqalo.
Bahlala ezimeni eziningi ezahlukahlukene futhi bazala kalula. Zifanele kahle kulabo abafuna ukuzama ukuzalanisa izinhlanzi okokuqala ngqa.
Akunzima kangako ukunakekela, kepha kudla zonke izinhlobo zokuphakelayo. Kungcono ukubondla kaningana ngosuku, ngenani elincane lokudla, ngoba izinhlanzi azikho kakhulu.
Ukondla
Njengoba zingama-omnivore, zidla ngenjabulo zonke izinhlobo zokudla okubukhoma, okubandayo noma okwenziwe e-aquarium. Akunzima ukubondla e-aquarium, cishe zonke izinhlobo zokudla zilungile.
Ama-flakes, ama-pellets, ukudla okubukhoma nokubandayo, into esemqoka ukuthi inhlanzi ingakugwinya. Kungcono ukondla ama-2-3 ngosuku, ngezingxenyana ezincane, ngoba inhlanzi cishe ayikudli ukudla okuwele phansi.
Ukugcina ku-aquarium
Ama-Erythrozones agcinwa kahle emhlambini wezinhlanzi eziyi-6-7, ngakho-ke adinga i-aquarium yamalitha angama-60 noma ngaphezulu. Abazithandi kakhulu izimo zokuboshwa, into esemqoka ukuthi imibandela iyavumelana futhi ayinakho ukweqisa.
Zikhula kahle emanzini athambile futhi ane-asidi, kepha izinhlanzi ezithengiswa endaweni yakho sezivele zivumelane nempilo ezimweni ezihlukile.
Ukukhanya kokugcinwa kwanoma yimaphi ama-tetra kufanele kuhlakazeke futhi kufiphale, ama-erythrozones nawo ahlukile. Indlela elula yokufeza lokhu ukubeka izitshalo ezintantayo ebusweni be-aquarium.
Ipharamitha ebaluleke kakhulu ukuhlanzeka kwamanzi nokuqukethwe okuphansi kwe-ammonia nama-nitrate. Ukuze wenze lokhu, udinga ukushintsha ingxenye yamanzi masonto onke bese usebenzisa isihlungi ku-aquarium.
Amapharamitha wamanzi wokuqukethwe: izinga lokushisa 23-28C, ph: 5.8-7.5, 2 - 15 dGH.
Kuyinto efiselekayo ukudala i-biotope yemvelo ku-aquarium. Umhlabathi ongezansi uyisihlabathi somfula omnyama, nezinkuni zokukhukhumeza namatshe amancane njengemihlobiso. Ungafaka futhi amaqabunga ezansi, okuzonikeza amanzi umbala obunsundu.
Azikho izitshalo eziningi emifuleni lapho kuhlala khona i-erythrozonus, ngakho-ke ayidingi amahlathi aluhlaza.
Ukungafani ngokocansi
Izinsikazi zikhulu, zigcwele kunabesilisa, zona ezinomusa ngokwengeziwe futhi zinemibala egqamile.
Ukuzala
Ama-spawners kulula ukuzala, kepha kwabaqalayo kuzoba yinto ezuzisayo.
Ukuzalanisa, lungisa i-aquarium ehlukile ngamanzi athambile angabi ngaphezu kwe-6 dGH ne-pH engu-5.5 kuye ku-7.0.
Kunconywa ukusebenzisa i-peat ukuthola leyo mingcele.
Ukushisa kwamanzi kukhuphuke kube ngu-25-28 C.
Izimbewu kufanele zikhanyiswe kancane, ukukhanya kwemvelo okuphezulu. Kusuka ezitshalweni, kusetshenziswa ubulembu baseJavanese noma ezinye izitshalo ezinamaqabunga amancane.
Abakhiqizi bondliwe ukudla okuphilayo kuze kube kahlanu ngosuku. Okufiselekayo okuhlukahlukene, imisundu yegazi, i-brine shrimp, i-tubule, njll.
Lapho lezi zithandani sezikulungele ukuzala, owesilisa uqala ukujaha insikazi, alume amaphiko akhe futhi aqhaqhazele phambi kwakhe ngomzimba wakhe wonke.
Ngemuva kwesikhathi esithile, ukuqomisana kuphenduka ukuzala, lapho inhlanzi iphenduka ngomhlane ikhiphe amaqanda nobisi. Imvamisa inani lamaqanda lisuka ku-100 liye ku-150.
Abazali abanaki i-caviar futhi bangaze bayidle, ngakho-ke badinga ukutshalwa ngokushesha. Amanye ama-aquarists asebenzisa inetha lokuphepha elibekwe ezansi.
ICaviar ibucayi kakhulu futhi kuyanconywa ukuthunga i-aquarium. Cishe usuku, isibungu sizobhuquza, futhi gazinga lizobhukuda kwezinye izinsuku ezintathu.
Kakade ngemuva kwamasonto amabili, gazinga liphenduka isiliva okokuqala ngqa, bese kuthi ngemuva kwamasonto amathathu libe nomugqa. Ekuqaleni, idinga ukondliwa ngama-ciliates nama-nematode, futhi ngemuva kwesikhashana kufanele idluliselwe ku-Artemia nauplii.
