Nyob rau kaum xyoo dhau los, muaj kev nthuav dav hauv kev lag luam thoob dej yug ntses nrog kev qhia txog cov ntses me me thiab cw rau nano thoob dej yug ntses.
Hauv kev ua lag luam twg, koj tuaj yeem pom cov ntses me me, thiab ntau cov cw yog ua rau koj ob lub qhov muag khiav qus. Cov neeg tsim khoom txawm pib tsim cov cuab yeej tshwj xeeb rau nano-thoob dej yug ntses, yog li lawv thiaj li nrov.
Ntawm cov ntses rau nano-thoob dej yug ntses, ntses ntawm lub genus Boraras (Boraras) lossis micro sibtham sawv kev sib cais, thaum muaj rau ntawm lawv.
Xav tias lawv zoo nkauj heev, haum, tsis ua tiav, thiab kuj tseem me me, qhov laj thawj ntawm lawv cov neeg tuaj yeem nkag siab. Tab sis, zoo li nrog cov ntses feem ntau tshiab, ntau cov lus sib cav tau tawm hauv Is Taws Nem txog cov ntsiab lus.
Cia peb sim paub seb qhov twg yog qhov tseeb thiab qhov twg tsis yog.
Cov Ntsiab Lus
Lub sijhawm no, muaj rau 6 hom ntawm cov ntses no, thiab nws yog qhov zoo dua los piav qhia lawv hauv millimetres, thiab tsis yog hauv centimeters.
Nws:
- rasbora pygmy (Boraras maculatus) yog qhov loj tshaj plaws, ntau npaum li 22 hli
- disassembly crumb lossis micro (Boraras micros) - 13 hli
- rassbor kab hluav taws (Boraras urophthalmoides) - 16 hli
- rassba ntsuas los yog liab (Boraras merah) - 16 hli
- rassbora briggita (Boraras brigittae) - 18 hli
- rasbora nevus (Boraras naevus) - 12 hli
Ib lossis ob lwm hom tsiaj twg tshwm sim rau ntawm kev ua lag luam, tab sis lawv tsis muaj lawv tus kheej lub npe, thiab muag hauv qab cov npe sib txawv.
Nco ntsoov tias rau Lavxias-hais lus aquaristics, qee hom kuj tseem paub me ntsis thiab cov npe ntawm lub neej tom ntej kuj tseem yuav txawv ntawm qhov tseeb.
Tab sis dab tsi yog muaj, lawv hu ua rasbora, ces microrassors ... peb yuav hu lawv qhov no thiab qhov ntawd.
Txawm hais tias tag nrho cov ntses no tau dhau los ua tsaug rau nano thoob dej yug ntses, lawv tau zoo khaws cia rau hauv cov hwj loj dua, 50-70 litres.
Tab sis, nyob rau hauv ib pab tsiaj loj thiab pom, uas zoo li ntxim nyiam tiv thaiv cov keeb kwm ntawm cov av dub, snags, thiab hav txwv yeem ntawm Cryptocoryne lossis Anubias. Ntxiv rau, qhov muaj cov driftwood lossis poob ntoo qhib nplooj hauv dej yog qhov tseem ceeb hauv kev ua kom me nyuam.
Nyob rau hauv cov xwm txheej, rasbora feem ntau pom nyob rau hauv cov dej hauv pas dej tsis muaj zog lossis tsis muaj dej, yog li nws yog qhov zoo dua los tsim cov xwm txheej tib yam hauv cov thoob dej yug ntses.
Piv txwv, lub lim me me sab hauv yuav tsim ib qho tam sim no ze rau ntawm cov dej, tab sis hauv cov tuab nws yuav luag pom.
Kev ntsuas dej yog qhov tseem ceeb thaum cuam tshuam nrog cov ntses nuv ntses. Feem ntau ntawm lawv los ntawm cov chaw uas tus pH tsuas yog 4.0 thiab dej yog muag heev.
Raws li, yog tias koj hloov lawv mus rau hauv dej nrog dej nyuaj, ces qhov no muaj kev ntxhov siab ntau.
Tsiaj qus Boraras yuav tsum tau ceev cia hauv dej thawj zaug, uas nyob rau hauv cov nqe lus ntawm tsis yuav zoo li ze tau rau qhov ntawd. Koj yuav tsum siv tsawg kawg 50% ntawm dej osmosis, ntxiv rau peat.
Nrog kev pab me me, hloov dej tsis tu ncua, rassors yoog raws li cov xwm txheej tshiab hauv ob peb lub hlis.
Lawv tau siv los nyuaj, ntau cov dej alkaline thiab nyob zoo txaus, txawm hais tias tsis yog txhua hom tsiaj tuaj yeem raug diluted hauv cov dej zoo li no.
Feem ntau, rasboros yoog thiab nyob hauv dej nrog pH ntawm 6.8-7.2 thiab nruab nrab hardness, tsis muaj teeb meem. Tshwj xeeb yog hais tias koj yuav cov ntses uas bred hauv koj thaj chaw, thiab tsis coj los ntawm qhov.
Pub khoom noj
Lawv yog cov tshuaj tua kab los ntawm xwm, tab sis hauv cov thoob dej yug ntses lawv noj plaub ya ri, pellets, zaub mov khov (brine cws, daphnia) thiab cov zaub mov muaj sia, xws li cov tubifex.
Tab sis, yog tias koj xav yug cov micro-pub mis, koj yuav tsum pub zaub mov kom ciaj xwb, ntxiv plaub ya ri ob peb zaug hauv ib asthiv xwb. Ib feem tseem ceeb ntawm kev pub mis yog pub loj.
Lawv xav tau cov khoom noj nruab nrab - cov ntses cij nauplii, brine cws nws tus kheej (khov nws muaj cov ntawv me me), daphnia, moina thiab lwm yam zaub mov.
Raws li Western aquarists, pub mis nrog nematodes, lossis raws li lawv tseem hu ua microworms, tshwj xeeb yog pab tau.
Qhov loj tshaj plaws yog pub tsis tau tsuas yog cov laus cua nab uas nkag rau hauv huab cua, tab sis kuj muab rau cov tub ntxhais hluas, uas feem ntau yog pub rau kib.
Ib qho tseem ceeb nuance
Lwm lub hauv paus ntsiab lus tseem ceeb hauv kev khaws lub tsev pheeb suab yog nyob rau hauv cov thoob dej yug ntses nrog lawv, hauv qab yuav tsum tau them nrog nplooj ntoo qhuav.
Qhov tseeb yog tias nyob rau hauv cov chaw nyob ntawm cov hom ntawm boraras, hauv qab ntawm lub pas dej yog them nrog nplooj poob, ceg, snags. Hauv qee qhov chaw, txheej tau tuab heev ua rau cov dej ua cov tshuaj yej-kob, yuav luag opaque.
Thiab hauv lwm tus, qhov dej tob yog ob peb centimeters, txawm hais tias hnub no nws tau kwv yees li ib metre! Tag nrho cov chaw no yog tau sau nrog nplooj poob. Raws li nplooj thiab lwm cov nroj tsuag khib nyiab hauv qab, lawv dhau los ua tsev rau ntau cov kab mob thiab cov kab mob me me.
Lawv kuj tso cov tannins rau hauv dej, uas txo cov dej ua kom tawv thiab pH, thiab muab cov dej mus ua tej yam zoo sib xws hauv cov xim rau tshuaj yej. Los ntawm txoj kev, koj tuaj yeem kawm paub txog kev siv cov ntoo nplooj hauv cov thoob dej yug ntses los ntawm cov kab lus no.
Chaw Sau Ntawv
Hauv txhua hom rau ntawm lub cev muaj pob liab voos yog pom meej kev sib deev dimorphic, txhais tau tias Cov txiv neej thiab poj niam yooj yim pom qhov txawv. Hauv tsib hom, txiv neej liab liab lossis xim txiv kab ntxwv xim rau lawv cov fins thiab lub cev.
Boraras micros muaj qhov ci ua rau daj txiv neej nrog lub pob tshab. Thiab cov pojniam ntawm tag nrho rau hom muaj ntau yam xim, tsis muaj xim liab, nrog pob tshab, thiab fuller.
Lawv yog cov me dua cov txiv neej, tab sis rau cov ntses ntsuas 15 hli, qhov no yog qhov sib txawv tsis yog daim ...
Cov pojniam feem ntau ua luam dej sib txawv, nrog cov hluas lossis tsis yog txivneej. Cov txiv neej tseem ceeb ci ntsa iab ntawm cov xim qaim thiab tiv thaiv tsis tau lawv thaj chaw.
Lawv sib ntaus sib tua tas li, txawm tias qhov no tau hais tawm hauv kev sib txig sib luag pem hauv ntej ntawm txhua lwm tus thiab rab koob tus khub nrog fins. Lawv kuj teeb nyob rau hauv pem hauv ntej ntawm poj niam, kis lawv cov fins thiab txhaws nrog rau xim. Lub sijhawm no, lawv tso pheromones tso rau hauv dej, cia cov pojniam paub tias tus txiv neej npaj tau los ua qe.
Qee lub sij hawm lawv coj tus poj niam mus rau hauv cov nroj tsuag ntawm lawv thaj chaw, tab sis feem ntau cov poj niam nws tus kheej ua raws tus txiv neej mus rau hauv cov hav txwv yeem.
Spawning tseem muaj sijhawm thiab koj yuav ntsais thiab tsis pom nws. Cov khub luam dej ua ke nyob ze ntawm nplooj ntoo ntawm cov nroj tsuag, thiab feem ntau nteg qe hauv qab nplooj. Ntxiv mus, nws tsis yog qhov tsim nyog uas yuav muaj ntxhuab nyob hauv cov chaw muaj av, tib lub Javanese.
Raws li cov lus los ntawm cov chaw sib tham, txhua hom ntawm micro-ntxawm boraras spawned rau lwm yam nroj tsuag. Raws li txoj cai, tus poj niam nteg ib lossis ob lub qe ntawm ib lub sijhawm, ib lub kaum os lossis ib lossis ib nrab kaum qe qe txhua hnub.
Tus txiv neej, ntawm qhov tod tes, yog ib txwm npaj rau spawning, nws saib tom qab, sib ntaus, tawm suab txhua hnub thiab tsis txhawj txog txhua qhov ntawm tus xeeb ntxwv tom qab yug menyuam.
Hauv ib lub thoob dej ntses nrog micro-txau, qhov chaw uas muaj driftwood, nroj tsuag, nplooj, tsis muaj lwm tus ntses, thiab cov mov nws tus kheej tau muab pub nrog cov zaub mov muaj sia, tsis tas yuav tsim cov kev mob tshwj xeeb rau kev txij nkawm.
Lawv nteg qe tsis tu ncua thiab tsis xav txog lawv lub kib ua zaub mov.
Lwm lo lus nug yog seb nws puas tsim nyog khaws cov cw rau hauv nano-thoob dej yug ntses nrog rau kev sib sau me me? Yog tias koj tsuas yog khaws cia rau kev zoo nkauj, tom qab ntawd heev. Cws yuav ci teeb koj lub thoob dej yug ntses thiab coj nws los rau lub neej.
Tab sis, yog tias koj xav yug lawv, ces koj tsis tsim nyog. Nws yog qhov zoo dua rau tshem tawm lwm cov ntses, ntses chaw, qwj los ntawm cov thoob dej yug ntses, txawm tias lawv tsis chwv cov kib. Lawv yuav nrog lawv sib tw ua zaub mov noj thiab tiv thaiv cov ntses kom tsis txhob muaj qe, ntxiv rau lawv yuav noj qe.
Xaus
Yog tias koj tab tom xav txog ntawm nano thoob dej yug ntses thiab xav tau cov ntses muaj xim zoo nkauj uas muaj kev lom zem ua si thiab yooj yim saib xyuas, tom qab ntawd mus rau ib qho ntawm Boraras hom.
Yog tias koj lub tank ntau dua, ces tseem zoo dua. Muaj koj tuaj yeem tau txais tag nrho pawg ntawm cov ntses me me, ci, nquag ntses. Cia lawv tsuas yog ib thiab ib nrab centimeters ntev.
