Umbala we-polypterus endlicher unobuqili, kepha muhle, uqukethe umbala onsundu ophuzi noma ompunga ohlaza okwesibhakabhaka onezimbali ezihlaza okotshani, isisu sinombala omhlophe. Abesilisa bahluka kakhulu ngombala, ngombala omncane, kepha bancane kunabesifazane, i-anal fin emadodeni enenombolo enkulu yemisebe. Ubukhulu obukhulu ngamasentimitha angama-30 kuya kwengama-40, kuma-aquarium imvamisa imincane kuno-20-30 cm. Lake Lake Tanganyika indawo yemvelo.
I-endlicher polytherus ibonakala ngomzimba ophakeme, ogcwele ukuqina, ikhanda elicabalele elinezimpondo ezimbili ezimfushane ekhaleni, isikali sendlulamithi ye-rhombic, imikhala ephakathi kwengu-15-18, kanye nama-lobes emisipha we-pectoral. Izinhlanzi zihola indlela yokuphila yesikhathi sobabili, kepha zihlala zikhuthele e-aquarium.
Umthamo ophakanyisiwe we-aquarium wokulondolozwa kwe-polypterus endlicher ungaphansi kwamalitha ayi-150-200. Amapharamitha anethezekayo: izinga lokushisa lamanzi 22- 28 °,, ukwehla kwesikhashana kuya ku-18 ° С noma ukukhuphuka kuye ku-32 ° С, dH 2-15 °, pH 6.5-7.5 kuvunyelwe. Ukuqina njalo kanye nokuhlunga kuyadingeka. Amanzi wamasonto onke aguqukela kukwesithathu umthamo we-aquarium.

Le polyperus ihlangana kahle nezinhlanzi ezihlala phansi: i-catfish ehlukahlukene, i-labyrinth. Kwamabha amakhulu nasheshayo, ama-atherin nama-characides, i-polyperus ivame ukulahlekelwa ngumncintiswano wokudlela, ngenkathi ihlala ilambile.

Ukudla kwe-polypterus endlicher kufanele kube nokudla okubukhoma. Ungadla izikelemu, igobolondo, izibungu zamadrako, gazinga noma umhluzi. Izinhlanzi zinomkhuba wokudla ngokweqile.
Kuzo zonke izinhlobonhlobo zezinto eziphilayo zasemanzini, i-leeches ziyingozi enkulu. Uma kwenzeka kulimala, kubalulekile ngesikhathi esifanele, kuze kube yilapho sekuphele inhlanzi, engeza i-methylene eluhlaza okwesibhakabhaka ngesilinganiso esingu-10-50 mg / ilitha kokufaka okumnyama okuluhlaza okwesibhakabhaka kwamanzi, okungekho, noma kunjalo, okuthikameza ukulawula kwezilwane.

Ukuzalwa kwe-polypterus endlicher. I-polypterus ye-endlicher ifinyelela esikhathini sokuthomba eneminyaka yobudala engama-2-3. Ukuqalwa kwesizini. Ukugqugquzela ukukhiqizwa kabusha kuyaphindwa (kungapheli inyanga) ukufakwa kwamanzi athambile, ukukhuphuka kwesilinganiso sokuhamba kwawo kanye nokwehla kwe-pH kuye ku-6.8. Kuyasiza ukwengeza ithonsi eli-1 lesisombululo se-1% se-potassium iodide ngamalitha ayi-100 amanzi. Esikhathini sokuqhuma, owesilisa uvame ukuba nomfudlana emgqonyeni wamanzi omsila, bese kuthi uhlanya lwenhlunu lube lukhula ngokubonakalayo. Imidlalo yokuhlobanisa ihambisana nokuphuma emanzini, ukudansa owesilisa ezungeze insikazi enganyakazi futhi icindezele abakhiqizi bebhekene.
Owesifazane uphonsa ophuzi-oluhlaza okotshani, usayizi we-caviar osayizi omele ngenani lezicucu ezingama-250-500, awubeka ezitshalweni noma emhlabathini. Ezinsukwini ezine kamuva, ku-26 ° C, kuvela izibungu ezinama-gill angaphandle, abukeka kakhulu njengezinsizwa zama-amphibian newts. I-Cannibalism ithuthukiswe kakhulu ku-fry, ngakho-ke, ukuhlunga okubonakalayo okubonakalayo kuyadingeka. Ithuba lokusinda likhuphuka e-aquarium enkulu enezindawo zokukhosela eziningi ngendlela yezitshalo, izingcezwana zamabhodwe e-ceramic, i-driftwood kanye nokudla okufanelekile: iplankton encane, microworms, oligochaetes nokunye.
Isikhathi sokuphila se-polypterus endlicher ekuthunjweni yiminyaka eyi-8 noma ngaphezulu.
Igama lesiLatini yiPolypterus endlicheri, isisho esifanelana nesibalo esikhulu.

Incazelo

Le yinhlanzi enkulu efinyelela ku-75 cm ubude. Kodwa-ke, ifinyelela osayizi abanjalo emvelweni, kuyaqabukela e-aquarium engaphezu kwama-50 cm. Isikhathi sokuphila siyiminyaka eyi-10, yize kunabantu abahlala ekudingisweni okuningi kakhulu.

I-polypterus inamaphinifa amakhulu e-pectoral, dorsal ngesimo se-crest serated, idlula phakathi kwe-caudal fin. Umzimba onsundu onamabala amnyama ahlakazekile.

Kubalulekile ukuvala i-aquarium ngokuqinile, ngoba bayakwazi ukuphuma ku-aquarium futhi bafe. Lokhu bakwenza kalula, ngoba ngokwemvelo bangasuka endaweni egcina amanzi baye endaweni yokugcina amanzi ngomhlaba.

Njengoba i-polytherus ka-Endlicher ihola indlela yokuphila yasesikhathini, akadingi ukukhanya okukhanyayo ku-aquarium, futhi akadingi izitshalo. Uma ufuna izitshalo, kungcono ukusebenzisa izinhlobo ezinde ezinamaqabunga abanzi. Isibonelo, i-nymphaeum noma i-echinodorus.

Ngeke baphazamise ukunyakaza kwakhe futhi bazonikeza isithunzi esiningi. Kungcono ukutshala ebhodweni, noma ukumboza ezimpandeni ngezigobho namakhukhunathi.

I-Driftwood, amatshe amakhulu, izitshalo ezinkulu: konke lokhu kuyadingeka ukuze kugcinwe polypterus ukuze ikwazi ukucasha. Ntambama akasebenzi futhi uhamba kancane phansi ezansi efuna ukudla. Ukukhanya okukhanyayo kuyabacasula, futhi ukungabikho kwezindawo zokukhosela kuholela ekucindezelekeni.

Amancane we-multi-opharetha i-Endlicher angagcinwa ku-aquarium kusuka kumalitha ayi-100, kuthi izinhlanzi ezindala udinga i-aquarium kusuka kumalitha angama-800 noma ngaphezulu.

Ukuphakama kwawo akubalulekile njengendawo engezansi. Njengomhlabathi omuhle kakhulu ukusebenzisa isihlabathi.

Amapharamitha wamanzi akhululeke kakhulu okuqukethwe: lokushisa 22-27 ° C, pH: 6.0-8.0, 5-25 ° H.

Ukondla

Izimbangi zidla ngokudla okubukhoma, abanye abantu e-aquarium badla ama-pellets kanye nqoko. Kokudla okubukhoma unganikeza izibungu, ama-zifobas, ama-bloodworms, amagundane, izinhlanzi bukhoma. Frozen udla ukudla kwasolwandle, inhliziyo, inyama eyosiwe.

IPolypterus Endlicher ayinamehlo amancane, ngokwemvelo bathola inyamazane ngokuhogela nokuhlasela kusihlwa noma ebumnyameni.

Ngenxa yalokhu, badla ngokunethezeka e-aquarium futhi bafuna ukudla isikhathi eside. Omakhelwane abashesha bangabashiya belambile.

Ngabe ibukeka kanjani i-polytherus?

Lezi zidalwa ezimangalisayo zibukeka njengenyoka:

• inhloko ebanzi enamakhala amakhulu
• umzimba uphakeme kakhulu ngobude obungadluli kuma-90 cm.

Leli cala livikelwe yizikali ezinkulu ezakhiwe njengamadayimane. Ngokwakheka kwalo, ososayensi bathola inyoka - iprotheni eqinile eyayikhona esikalini senhlanzi ezanyamalalayo.

Okunye ukufaka uphawu okungajwayelekile kwe-dorsal fin, okuqala kusuka maphakathi emuva futhi kuphelela emsileni, futhi akuqhubeki, kepha kube sengathi kunqatshiwe (kukhona okukodwa okunje nge-15te vertebrae). Zonke izingxenye zawo zingavuka ziwe ngokucela kwenhlanzi.

Amaphinifa we-pectoral anamathambo amabili ahlukanisiwe, ahlukaniswe yi-cartilage. Ngosizo lwabo, izinhlanzi zingawela umfula uwele futhi ziphumule, zisebenzisa zona njengezisekeli.

Ukuzala

Izimo zokusakazwa kwezibhishi ezindlini zamanzi ziyaphawulwa, kepha imininingwane ekuyo ihlukene phakathi. Njengoba, emvelweni, izinhlanzi zidlakudla phakathi nenkathi yemvula, ushintsho ekwakhekeni kwamanzi kanye nokushisa kwalo kusebenza njengegalelo.

Ngokubuka usayizi wezinhlanzi, i-aquarium enkulu kakhulu enamanzi athambile, acwebile ayadingeka ukuze ihlakaze. Beka amaqanda emahlathini aminyene wezitshalo, ngakho-ke kudingeka ukuthi kuhlale kuqine.

Ngemuva kokuhluma, abakhiqizi badinga ukutshalwa, ngoba bangadla i-caviar.

Ngezinsuku ezi-3-4 izibungu zizodonsa ukusuka emaqanda, kuthi ngosuku lwesi-7 ukuthamela kuqale ukubhukuda. Ukuqala okuphakelayo - I-Artemia nauplii ne-microworm.

UKUDLA

Izimbangi zidla ngokudla okubukhoma, abanye abantu e-aquarium badla ama-pellets kanye nqoko. Kokudla okubukhoma unganikeza izibungu, i-zoobus, ama-bloodworms, amagundane, inhlanzi ebukhoma. Frozen udla ukudla kwasolwandle, inhliziyo, inyama eyosiwe.

IPolypterus Endlicher ayinamehlo amancane, ngokwemvelo bathola inyamazane ngokuhogela nokuhlasela kusihlwa noma ebumnyameni. Ngenxa yalokhu, badla ngokunethezeka e-aquarium futhi bafuna ukudla isikhathi eside. Omakhelwane abashesha bangabashiya belambile.

Yini okufanele ibe yi-aquarium?

Udrako waseSenegal akathobeki, kepha udinga ukunakekelwa okuhleliwe. I-Aquarium izodinga okungenani amalitha angama-200. Kufanele kube nesembozo ngaphezulu (kufanelekile, kepha kube nezimbobo) futhi kungcono ukuvala zonke izikhala ngokweqile, ngoba i-polyperus ingaphuma, iwele phansi futhi ifele phansi kusuka ekomile ukuphuma.

Isikhathi esiningi inhlanzi ichitha ezingxenyeni ezingaphansi zamanzi ifuna ukudla, ngezikhathi ezithile ikhuphukela phezulu emhlabeni ukuze iphefumule.

Amapharamitha wamanzi agcinwa kangcono kulawa mabanga alandelayo:

• Ukushisa okungu-24-30 degrees
• acidity 6-8,
• ubunzima 3-18 °,
• ukuhlunga,
• ushintsho lwamasonto onke.

Kuvunyelwe ukuhlobisa ichibi nge-grottoes, ngamatshe, ngemigibe. Izitshalo zingatshalwa, kepha ungakwenza ngaphandle kwazo. Ngokunakekelwa okuhle, amaSenegal angaphila iminyaka eyi-10.

Amapharamitha we-Aquarium

Kulolu hlobo lwe-polyterus, i-aquarium yamalitha angama-300 izokwanela. Ukuphakama akubalulekile, kepha akudingekile ukuthatha phezulu kakhulu. Ngokuqondene nokubuka kwangaphambilini, ukunakwa okukhethekile kufanele kukhokhwe kwisembozo nezimbobo ezivela kuma-hoses imishini.

Ichibi lingaba ngaphandle kokuhlobisa, kepha bese libukeka lincane. Njengoba umhlobiso ulingana nezibambo, amatshe, imihume. Uma izitshalo zihlelekile, khona-ke kungcono ukuthatha ama-mosses kanye nezinhlobo ezinamaqabunga alukhuni.

Izimo ziyefana neSenegalese polyterus. Ukunakwa ikakhulukazi kufanele kukhokhwe ekuhlanjululweni okuhle. Sifaka futhi ukuthi ukukhanyisa akudlali indima enkulu. Kuzokwanela futhi kuhlwe. Ungakhetha ukufaka izibani ze-bluish-spectrum ukuze uvule ebusuku lapho ukukhanya main kucinyiwe.

Uguliswa yini yi-polypterus?

Lokhu kwenzeka kakhulu futhi kungenxa yezimo ezingafanele zokuvalelwa.

Ukweqisa kuholela izinhlanzi ezikhuluphele. Ngokuvamile ukuhlanza isihlungi ezindaweni ezinamanzi amancane kuholela ekufiseni ubuthi be-ammonia. Ukutheleleka kwegciwane lesibili kuphakanyiswa kukho konke lokhu, okuholela ekubhekeni esikalini.

UMonogene. I-Lethargy, isifiso sokudla esibuthaka, ukukhuphuka njalo phezulu komhlaba ukuze uphefumule, ukungasebenzi futhi silele phansi kuyizimpawu zonke zalesi sifo. Lapho ehlolwa ngokucophelela, emzimbeni futhi ikakhulukazi ekhanda lezinhlanzi, umuntu angahlukanisa ama-monooqu ngokwawo, ukukhanya ngephethini emnyama yezimpethu. Lesi sifo sikhula ngokushesha. Bamphatha nge -yrazine.

I-Mnogoper ingaba ngabathwali izinhlwayi zamanzi ahlanzekile. Lokhu kusebenza kuphela ezinhlanzini ezibanjwe emvelweni. Ukuhlukaniswa kwabo (ngaphambi kokungena kwi-aquarium) kuyadingeka.

Sengiphetha, ngifuna ukusho ukuthi i-polyperus iseyinhlanzi yase-amateur, futhi ilungele kakhulu ama-aquarists athuthukile kunabaqalayo. I-aquarium enkulu akulula kangako ukuyigcina. Ngaphezu kwalokho, udrako wasekhaya awunakuba seduzane nazo zonke izinhlanzi ngokuthula. Futhi ngokubona lokhu akuyona into ethakazelisa kakhulu, ngoba isikhathi esiningi asichitha emashalofini noma aqhubekele ezansi lapho efuna ukudla. Kepha uma uthatha isinqumo sokufaka le dinosaur ku-aquarium yakho, bese uyayihambela!

Isingeniso

Ukuvela kwamaPolypoids kubhalwe ngesikhathi se-Cretaceous nenkathi yama-dinosaurs, i.e. ngaphezulu kwezigidi ezingama-60 ezedlule. Zonke izimpaphe zesimanje zama-Multi-Feather (Polypteridae) zivela emanzini ahlanzekile ase-Afrika. Umndeni uqukethe izinhlobo ezimbili. Esokuqala, iKalamoicht (Erpetoichthys), siqukethe inhlobo eyodwa kuphela - iKalamoicht Kalabar (E. calabaricus), eyaziwa ngenye inhlanzi yenyoka noma inhlanzi yomhlanga. Uhlobo lwesibili, i-Polypterus, liqukethe izinhlobo ezingaphezu kweshumi nambili kanye nezinhlobo ezithile (bheka ithebula elingezansi).

I-Photodare yi-Senegalese noma i-grey polyperus (P. senegalus) (pinimg.com) Isithombe sePolytherus delgesi (P. delhezi) (segrestfarms.com)

Igama elithi Polypterus lihumusha elithi “Lins of Fins,” libonisa esinye sezici zazo ezisobala: amaphini amaningi e-dorsal ngemuva. Ezinye izici eziphawuleka zifaka umzimba wenyoka amaphiko amakhulu we-pectoral, asetshenziselwa ukunyakaza futhi anikeze i-polypterus ngendlela ebonakalayo yokubhukuda. Kusetshenziswa umsila lapho ukusheshisa kuyadingeka. Izimpaphe eziningi zinezimpawu ezivamile nezinye izinhlanzi zasendulo. Isikali se-ganoid esiqinile sitholakala ezinhlanzini ezihlomile nezisilika (noma i-amia, Amia calva). Izimpaphe eziningi (Polypteridae) zinesibungu esishintshiwe sokubhukuda, okuthi njengamaphaphu, sihlukaniswe ngokuqondile zibe izingxenye ezimbili. Lokhu kuvumela izinhlanzi ukuba zibambe umoya omningi kusuka ebusweni - insiza ewusizo yamanzi komoya ophefumulwayo.

Izinhlobo ze-Aquarium ze-polypterus

Ezinye zezinhlobo zeMulti-Feather zingabahlali baphakade bezindawo zasemanzini. Phakathi kwazo kukhona i-polytherus delgesi (P. delhezi), i-polytherus ornatipinis (P. ornatipinnis), imfiva, imabula noma i-polypteruses yesundu (P. Palmas), kanye ne-Senegalese noma i-grey polypteruses (P. senegalus). Ezinye izinhlobo zivame kakhulu. Ezinhlotsheni ezivame kakhulu, i-polyperus noma i-bishir ebukekayo ibhekwe njengokuhlaba umxhwele ngokukhethekile. Ama-polypterus asePalm nawaseSenegal atholakala kabanzi futhi angabizi kakhulu (qaphela ukuthi empeleni angamalungu okubhaliswa, njengoba kukhonjisiwe etafuleni lezinhlobo).

Ukuvumelana Polypterus

Ama-polypterus wevidiyo anegolide

Imvamisa zigcinwa nanoma yiziphi izinhlanzi ezingenalo ulaka ezingeke zigwinywe ngoba ama-polypteruses awakhombisi ulaka kwezinye izinhlobo. Kodwa-ke, ngiphawule ukuthi ezimweni ezingandile, zingaluma izinhlanzi ezinkulu. Lokhu mhlawumbe kungumzamo oyiphutha wokuthola ukudla okuhambisana nokungaboni kahle.
Ukubona ubukhona bokudla emanzini, ipeni eliningi lincike ikakhulukazi emnweni wokuhogela. Imvamisa, lapho ukudla kufakwa e-aquarium, ishiya indawo yayo yokuphumula. Ngemuva kwalokho, ukudwayika, inhlanzi iqhubekela ekudleni, ize izifihle ngokoqobo kuyo. Kwesinye isikhathi ubhukuda esedlule, kodwa bese ebuya kancane, ezwe sengathi kukhona abaphuphile.

Yize zichazwa ngokuthi "abazingeli abahahayo" noma into enjengaleyo, ama-polypterus ikakhulukazi ama-adapter-glitter. Lokhu akusho ukuthi uma kungenzeka ngeke badle izinhlanzi ezincane! Ukuhamba kwabo kancane nokungaboni ngamehlo ampofu kusikisela ukuthi abakwazi ukubamba izinhlanzi ze-pelagic. Kodwa-ke, uma kunesidingo, umphikisi uhamba ngokushesha ngokumangazayo. Izinhlanzi ezincane zizoba sengozini enkulu uma kusondele ezansi ebusuku, lapho i-multiper isebenza kakhulu.

I-Polytherus idla izinhlobo ezahlukahlukene zokudla, ifaka imikhiqizo yenyama: igobolondo, imbaza, inhlwathi kanye nezinhlanzi zenyathi, ngokwesibonelo, i-smelt ne-atherinka. Ziphinde zidle ama-pellets e-catfish feed, bese ngibheka laba "abazingeli abahahayo" beba amapuleti e-algae e-catfish. Izilwane ezisencane zondliwa ukudla okuncane okwenziwe iqhwa, okufana nama -wwwwgazi, futhi zivame ukudla ukudla okusontayo.

Lapho uhlela i-aquarium yokusebenzelana okuningi noma ukulungisa enye ekhona, ubungako bezinhlanzi bungabhekelwa. Ngisho nezinhlobo ezincane ezise-aquarium zifinyelela ku-25-30 cm, kanti ezinye izinhlobo zikhula ngaphezu kuka-60 cm ubude. Isikhala esingaphansi sibaluleke kakhulu kunokuphakama kwe-aquarium, ngakho-ke uma kungenzeka, thatha i-aquarium ephansi ngesisekelo esikhudlwana. Kwezinye izinhlobo ezincane, kufanelekile ukuthi kusetshenziswe isitsha esinezisekelo ezingama-120 x 38 cm.Ukuhlalisa izinhlobo ezinkudlwana, i-aquarium engu-180 x 60 cm.Ngoba izinhlanzi kudingeka zikwazi ukuthola phezulu ebusweni ngezikhathi ezithile ukuze zithole umoya owengeziwe womoya, izindawo zasemanzini ezijulile aziluleki. Ngesizathu esifanayo, ithangi kufanele ihlale igcwaliswa ukuze kube negebe lomoya phakathi kwamanzi nesivalo. Kunconywe ukusebenzisa amabhodlela afanelekile, njengoba izinhlanzi zinamandla okuphuma ku-aquarium, ikakhulukazi, inhlanzi yenyoka inedumela njengengcweti yamahlumela.

UMnogoperov wayevame ukubiza ngolaka maqondana nezinhlobo zakhe nezinye ze-mnogoperov. Futhi yize bengakwazi ukuzijikijela omunye komunye, ikakhulukazi ngenxa yocezu lokudla, imvamisa lokhu kuziphatha akumlimazi muntu. Uma uzikhethe kahle izinhlobo zezinhlobo ngosayizi futhi wazinikeza isikhala esidingekayo, khona-ke ngeke uhlangabezane nanoma yiziphi izinkinga ezinkulu zobudlova phakathi kwabantu. Kodwa-ke, njengakwezinhlanzi eziningi, kukhona okuhlukile, futhi noma yibaphi abantu ababonisa njalo ubudlova kufanele bagcinwe bodwa.

I-Aquarium yama-polythers - ukukhanya okufiphele, indawo yokuhlala eningi nesihlabathi esithambile

Abanye basikisela ukugcina okuphindaphindwayo emanzini angenalutho ukuze kuncishiswe amathuba wokuziphatha kwendawo. Kodwa-ke, kuyadabukisa ukubona izinhlanzi endaweni engenamuntu ngaphandle kokuhlobisa noma indawo yokucasha. Ngakolunye uhlangothi, kuhle ukubuka ama-polythers ehamba kancane phakathi kwamatshe nezibambo ku-aquarium ehlome kahle. Umhlobiso ofanelekile wakhelwe phezu kwesisekelo samatshe abushelelezi nezingcezu ezinkulu zokhuni olubhukuda, olubekwe ukuze kwakheke imihume embalwa. Amapayipi e-Ceramic noma epulasitiki azoba enye indlela efanelekile, yize ezobukeka emincane ngokwemvelo. Akunasizathu sokuthi lezi zinhlanzi zingagcinwa e-aquarium enezitshalo. Akunakwenzeka ukuthi bazodla noma bawonakalise ngamabomu izitshalo, yize abantu abakhulu kungenzeka ukuthi babonakala “bebaningi” ezindaweni zasemanzini ezitshalwe kahle, kanye ne-catfish enkulu.Ngakho-ke, kunconywa ukusebenzisa izitshalo eziqinile ezinamathele kalula ematsheni nasezinkuni (ngokwesibonelo, iJavanese fern noma iJavanese moss). Ezinye zezitshalo ezikhona zepulasitiki noma zesilika zingasetshenziswa ukwakha indawo yokukhosela.

Ukuhlunga kwanoma yiluphi uhlobo kufanelekile, kuhlinzeka ukusebenza okwanele kwe-biofiltration. Yize lezi zinhlanzi zingasebenzi ngokweqile noma zidla izambane likapondo, ukudla kwenyama okudingayo ngaphandle kokuhlunga okwanele kungangcolisa amanzi ngokushesha. Ngincamela ukusebenzisa izihlungi zangaphandle (ama-canisters) noma ezinye izinhlobo ezine-biofiltration enamandla. Noma iyiphi i-heater yesimanje izoyenza. Sebenzisa ukuvikelwa kwe-heater noma isihlungi sangaphandle somoya ukuze uvikele ukulimala kwehekitha ngalezi zinhlanzi ezinamandla.

Amanzi we-polypterus

Ngokufanelekile, lezi zinhlanzi kufanele zigcinwe ezingeni eliphezulu lobubanzi bezindawo ezishisa kakhulu, i.e., cishe ngo-25-28 ° C. Amanzi athambile noma athambile kancane nge-pH engathathi hlangothi noma i-acidic encane kungenzeka ilungile, kepha ukwakheka kwamanzi akubalulekile uma ikhwalithi yayo igcinwa njalo ngokushintshwa okuvamisile. Ukuba khona kwezinhlobo ezimbili zezimpaphe eziningi eLake Tanganyika (i-polypterus (P. ornatipinnis) ne-Endlicher polypterus (P. endlicheri congicus) kusikisela ukuthi ziyavumelana nokwakheka kwamakhemikhali emanzini. Lezi zinhlanzi zibhekwa njengezinzima kakhulu futhi zingakwazi ukumelana nemithi, kodwa ungabheki amakhono abo ku-aquarium!

Ukukhanyisa akubalulekile kakhulu, ikakhulukazi lapho kungekho khona izitshalo eziphilayo. Ubusuku obuningi, ama-polypterus akhetha ukukhanya okukhanyayo, yize izinhlanzi ezincane zibonakala zingathinti ukukhanya okukhulu ngenkathi zidla. Mhlawumbe kufanelekile ukuhlinzeka nge-aquarium ngesibani esisodwa se-“moonlight” eluhlaza okwesibhakabhaka futhi sikuvule ihora noma amabili kusihlwa. Setha isibali sikhathi ukuze ukukhanya lokhu kukhanye ngaphambi kokukhanya okukhulu, ukuze ukuguquka kube ngukukhanya kungokwemvelo ngokwengeziwe. Ngokukhanya okungekuhle kwe-aquarium, ngokwesibonelo, kusukela ekukhanyisweni kwangemuva kwekamelo, umsebenzi uzokhula ngokubonakalayo.

Izinhlanzi ezi-Mnogoper eziqine kakhulu, azihlaselwa isifo. Izikali zabo eziqinile ze-ganoid zinikeza isivikelo esikhulu ekulimaleni okubangelwa ukutheleleka ngegciwane noma isikhunta, futhi kubuye kubenze bamelane kakhulu namagciwane athile. Kodwa-ke, abantu abasanda kwethulwa kungenzeka ukuthi bathwala i-leech yamanzi amnyama iMacrogyrodactylus polypteri, enamathela emzimbeni wenhlanzi. Ekufuneni impumuzo, inhlanzi izama ukulunywa, lokhu kuziphatha kubizwa ngokuthi "ukushaywa" noma "ukuthuthumela." Izindawo zokugeza zika-Formalin zisusa ngempumelelo lezi zinambuzane. Ngaphambi kokuthenga, hlola izinhlanzi ngokucophelela.

Ukwahluka kocansi ezimpaphe ezinamaphawu amaningi akusobala, kepha abesilisa abadala bangahlukaniswa yibhola ebanzi ne-thick fin. Kuyacatshangelwa nokuthi zinemisipha emincane. Abesifazane bavame ukuba bakhulu ngosayizi. Intsha ayinakho umehluko ocacile. Izinhlobo eziningi zalaliswa ekudingisweni, kufaka phakathi i-motley ne-Senegalese polypterus ne-Endlicher polypterus. Kodwa-ke, ukusatshalaliswa ku-aquarium yasekhaya kusalokhu kuyivelakancane.

Amathuba okuphumelela aphezulu kumanzi athambile, acwebile. Izinguquko ekushiseni nasekubunjweni kwamakhemikhali emanzini kubonakala kuvusa ukuqhuma. Owesilisa wenza inkomishi yama-anal ne-caudal fins endaweni yesitho sangasese sowesifazane, lapho insikazi ibeka amaqanda okuzala, emva kwalokho amaqanda anamathela ahlakazekele izitshalo. Kule nhloso kusetshenziselwa izitshalo ezinamagatsha amancane (“isiponji sokuhlanza”). Kuvunyelwana ngokuvamile ukuthi ngemuva kokuhlwaywa, abazali kufanele batshalwe ngokushesha ngangokunokwenzeka ukuzebavimbele ekudleni i-caviar (noma gazinga). Amaqanda acishe abe ngu-2-3 mm ubukhulu, amaqanda ezibungu ngemuva kwezinsuku ezingama-3-4. Ukondla kufanele kuqale isonto elizayo, lapho okuqukethwe ama-yolk sacs.
