Enye ye izinhlanzi ezinhle kakhulu zamanzi ahlanzekile I-bluegill, eyaziwa nangokuthi i-luminous mojarra noma i-blue acara. Le nhlanzi, igama layo lesayensi I-Aequidens pulcher, igqama ngombala nokuziphatha kwayo okumangalisayo. Itholakala emifuleni yaseTrinidad naseTobago, eVenezuela kanye naseColombia, i-bluegill isiphenduke enye yezinhlobo ezidume kakhulu ezindaweni ezihlala emanzini.
Umsuka nokusatshalaliswa
I-bluegill ihlala kuyo imifula nemifula yaseNingizimu Melika, ikakhulukazi e-Caribbean Basin, e-Catatumbo Basin nase-Orinoco River Basin. Nakuba ivela eVenezuela naseTrinidad naseTobago, namuhla kungenzeka futhi ukuyithola eColombia, ezindaweni ezinjengeCiénaga Grande de Lorica.
Lezi zifunda zibonakala ngamanzi okushisa ashisayo, ngokuvamile anezitshalo eziminyene kanye namanzi anamazinga amanje amaphakathi. Ikhono layo lokuzivumelanisa nezimo ezihlukahlukene zamanzi lenze laduma ezindaweni ezihlala emanzini asekhaya.
Izici zomzimba ze-bluegill
Umzimba we-bluegill u-oval futhi uqinile, unomlomo isikhathi eside ikuvumela ukuthi ubambe inyamazane encane kalula. Ukwengeza emigogodleni emithathu ephikweni lendunu, ibluegill inombala ocebile oyihlukanisa kwezinye izinhlanzi ze-cichlid: a oluhlaza okotshani enamabhande amnyama ajikayo emzimbeni kanye nemigqa eluhlaza okwesibhakabhaka ehamba ezihlathini zayo.
Kukhona ama-dimorphisms ocansi acacile phakathi kweduna nensikazi. Abesilisa ngokuvamile banombala ogqame kakhulu futhi bangafinyelela osayizi abakhulu kunabesifazane. Ngosayizi, abesilisa bangafinyelela ku-15 cm, kanti abesifazane bavame ukuba bancane, bazungeze u-12 cm.
Indawo yokuhlala ye-Aquarium nezimo
Ukuze ama-bluegill aphumelele ekuthunjweni, i-aquarium kufanele iphindaphinde izimo zendawo yazo yemvelo ngokuseduze ngangokunokwenzeka. Ngezansi amanye amapharamitha anconyiwe ukuze uzuze inhlalakahle yakho:
- Usayizi we-Aquarium: Okungenani amalitha ayi-100 kumbhangqwana.
- Izinga lokushisa lamanzi: Phakathi kuka-24 no-28°C.
- i-pH: Ine-acidic kancane ukuya kokumaphakathi, phakathi kuka-6.5 no-7.5.
- I-Dureza del agua: 5 kuya ku-15 dGH.
I-aquarium kufanele ibe nesikhala esanele sokubhukuda, njengoba ziyizinhlanzi ezikhuthele, nezitshalo eziqinile ezifana I-Anubias o I-Microsorum. Kubalulekile futhi ukufaka amatshe noma izingodo ukuze bakwazi ukufihla futhi basungule indawo yabo. I-Bluegill ijwayele ukuba yindawo, ikakhulukazi uma ibhanqiwe, ngakho-ke kutuswa ukugwema ukubeka izinhlanzi eziningi endaweni efanayo ukuze kuvinjelwe izingxabano.
Iphuzu elibalulekile ukuthi lezi zinhlanzi ziyakhiqiza imfucuza enkulu, ngakho-ke kubalulekile ukwenza izinguquko zamanzi ngokwengxenye kaningi (cishe u-20-30% wamanzi amasonto onke). Ngaphezu kwalokho, kuhle ukuba nesistimu yokuhlunga enamandla ukuze ugweme ukuqoqwa kwezinto ezinobuthi ezifana ne-ammonia noma i-nitrites.
I-Bluegill Yokudla
I-bluegill ingu-a izinhlanzi omnivorous, okusho ukuthi emvelweni idla kokubili izitshalo nezilwane ezincane ezizingelayo. Endaweni yazo yemvelo, ukudla kwalezi zinhlanzi kuhlanganisa izinambuzane zasemanzini, ama-crustaceans nezinhlanzi ezincane. Kodwa-ke, ekuthunjweni kubalulekile ukuqinisekisa ukudla okuhlukahlukene ukuze kugcinwe umbala ogqamile futhi ujabulele impilo enhle.
- Ukudla okubukhoma: Izikelemu zegazi, izibungu zomiyane, nama-brine shrimp yizinketho ezinhle.
- Ukudla okuqandisiwe: Izimfanzi eziqandisiwe ze-brine, i-daphnia ne-krill.
- Ukudla kwezentengiso: Ama-granules athile noma izinti zama-cichlids anothe ngamaprotheni.
- Ingxenye yesitshalo: Isipinashi esibilisiwe, ikhukhamba noma uphizi ngezikhathi ezithile ukuze ungeze ekudleni kwakho.
Khumbula lokho Akunconywa ukuphakela i-bluegill ukudla okune-flake kuphela., njengoba uzodinga ukudla okunamaprotheni amaningi ukuze uhlale unempilo. Ukwengeza, kuhle ukupha lezi zinhlanzi izikhathi eziningana ngosuku ngamanani amancane ukuze kugwenywe ukunqwabelana kwemfucuza emanzini.
Ukuziphatha nokuhambisana
Nakuba bluegill ngokuvamile enokuthula, ingaba yindawo, ikakhulukazi ngesikhathi sokuzala. Azizona izinhlanzi ezivame ukuxosha ezinye izinhlobo zezilwane, kodwa zizofuna ukuvikela indawo yazo ngokuqinile. Ngalo mqondo, uma isikhala ku-aquarium silinganiselwe, kungase kuphakame izingxabano nezinye izinhlanzi.
Mayelana nokuhambisana nezinye izinhlobo de peces, i-bluegill ingahlalisana nezinhlanzi zomphakathi ezinosayizi ofanayo nokuziphatha okungewona ulaka. Ezinye izinketho ezinhle zihlanganisa i-catfish I-Corydoras noma inhlanzi Angel. Kodwa-ke, kufanele ugweme ukwethula izinhlobo ezincane ezifana nama-tetra noma ama-guppies, njengoba zingabonakala njengezilwane ezizingelayo.
Uma i-aquarium inesikhala esanele nezindawo zokucasha, ama-bluegill angahlala namanye ama-cichlid, inqobo nje uma izindawo zawo zihlonishwa. Enye inketho ukugcina ipheya eyodwa ku-aquarium enikezelwe bona.
Ukukhiqiza kabusha ku-aquarium
I-bluegill iwuhlobo oluthile i-oviparous futhi kulula ukukhiqiza kabusha ezindaweni ezihlala emanzini. Ukuze ukuzala kwenzeke, kubalulekile ukuthi kwakhiwe ipheya. Lapho kukhwelana, amaduna nezinsikazi zizohlala ndawonye kuyo yonke inqubo yokubeka nokunakekela amaqanda nezibungu. Ngesikhathi sokuqomisana, owesilisa uzocula ukunyakaza okudlidlizayo ngamaphiko abo ukuheha owesifazane.
Ukuzalanisa izimo ze-aquarium
- i-pH: Imaphakathi, phakathi kuka-6.5 no-7.0.
- Ithempelesha: Gcina amanzi ephakathi kuka-24 no-26°C ukuze kube lula ukuzala.
- I-aquarium ehlukile: Okufanelekile, yiba ne-aquarium yokuzalanisa okungenani amalitha angama-40.
Lapho insikazi isikhethe indawo eyisicaba njengetshe elihlanzekile, izobeka amaqanda ayo lapho, bese eyeduna iqhubeke nokuwavundisa. I Amaqanda azochanyuselwa ezinsukwini ezi-2 kuya kwezi-5. ngemva kokubekwa, futhi okuthosiwe kuzodla esikhwameni se-yolk izinsuku ezimbalwa ngaphambi kokuqala ukudla ukudla okuphilayo okufana ne-brine shrimp nauplii.
Ukunakekelwa kwe-Fry
Ngemva kokuba amaqanda achanyuselwe, kokubili iduna nensikazi banomthwalo wemfanelo wokuvikela amaphuphu. Eyeduna ingathatha amazinyane emlonyeni wayo ukuze iwavikele lapho kwenzeka ingozi. Okuthosiwe, ngemva kokudla isikhwama se-yolk, kufanele kuphakelwe ama-rotifers noma i-brine shrimp nauplii kuze kube yilapho sebekwazi ukudla ngama-pellets amancane noma ukudla okudayiswa kwempuphu.
Isici esifanelekile ukuthi umbhangqwana uzoqhubeka nokuvikela i-fry phakathi namasonto okuqala, kuze kube yilapho izinhlanzi ezincane zikwazi ukuzinakekela.
Ngamafuphi, i-bluegill iwuhlobo oluhehayo ngobuhle bayo nokuziphatha kwayo. Nakuba idinga ukunakekelwa okuthile, ukukhiqizwa kwayo ekuthunjweni kanye nesimo sayo sengqondo sendawo kuyenza ibe yisinqumo esihle kakhulu kuma-aquarists anolwazi oluthile, abafuna inhlanzi esebenzayo nengavamile ye-aquarium yabo.
