World Aquarium nsomba: nsomba mpeni

Nsomba mpeni (banja apteronotovyh) nalo dzina lake pa lathyathyathya mawonekedwe tapered, chokhala mpeni. Malo amene nsomba - wosakwiya ukusuntha ndi mayiwe atachuluka wa beseni Amazon (Bolivia, Peru, Brazil, Colombia). The Aquarium apteronotus angafikire kutalika masentimita 30-40, ndipo mu chikhalidwe - masentimita 50.

Apteronotus belokaymovy (kapena wakuda mpeni) ali ndi thupi elongate, zopanda mamba, ndi mzere lakuthwa mwa mimba. M'dera la mchira iwo ili thupi limatulutsa ofooka zikhumbo magetsi kuti kulola nsomba kudziteteza kwa adani ndi nthawi imodzi kuyenda madzi kale loipa. Ventral ndi dorsal zipsepse ayi, koma bwino anayamba kumatako, amene amayendetsa kuchokera kumutu mpaka kumchira. Kupanga undulations izi chipsyepsye ndi kusintha mabere awo, nsomba mpeni akhoza kusuntha kwina kulikonse, ndipo pa liwiro (kutsogolo ndi m'mbuyo komanso mmwamba ndi pansi). The chipsyepsye caudal ndi mwachilungamo yaing'ono. Mtundu - veleveti wakuda, ndi mzere woyera akuthamanga kumbuyo. Pa caudal peduncle - awiri mikwingwirima yopingasa chikasu woyera mu mawonekedwe a maliboni. Akazi amasiyana amuna ang'onoang'ono ndi zambiri otchuka mimba. Amuna akhoza kukhala nawo kumbuyo kwa mutu wake pang'ono mafuta chotupa.

Black mpeni - nsomba okonda mtendere, ngakhale manyazi, mmene ntchito usiku. khalidwe mtendere Komabe, si chopinga mu kusakasaka nsomba ang'onoang'ono. Nsomba Mpeni - mdani ndi kukhulupirira kuti ndife opanda pake nsomba, tadpoles, nyongolotsi, nkhanu. Nsomba za mtundu moyo mu madzi wobvutika ndi kuyenda, ndipo ngakhale usiku, angakhale chifukwa zikhumbo za magetsi, komanso zolandilira yomwe imakhala kutalika kwa thupi. Pamene kusuntha nsomba mpeni amalenga minda atomu, amene amalola ake kuona nyama, zomwe ndi kwina kulikonse.

Nsomba mpeni Aquarium zili ake amafuna thanki 200 L ndi pamwamba ndi aeration amphamvu, peat fyuluta madzi kutentha kwa 24-28oC, ndi pH 6-7, 2-10o chinthu chimodzimodzi. Amakonda zachinsinsi, choncho akufunika kukhala Chotetezera pawekha mawonekedwe a snags kukongoletsa machubu kapena mapoto. kusintha madzi ayenera kamodzi pa sabata, 35% buku la thanki. Apteronotus belokaymovy atengeke ich. Muyenera kudziwa kuti mankhwala a matenda Mulimonsemo ali osavomerezeka ntchito mankhwala, kuphatikizapo nthaka.

Pamene zili Aquarium, ndi zofunika polenga zinthu kwa nsomba, pafupi ndi masoka. Pakati pa amuna amayambira ndikawapempha, kotero chivundikiro cha ayenera kokwanira. M'pofunika kuganizira kukula kwa mipeni nsomba ndi mwachinsinsi ndi kukula mitundu ina ya nsomba: nsomba kochepa kutenga pa chakudya, ndi mafoni kwambiri ndi mwamakani anansi kuwapatsa anachitazi. Choncho, apteronotus atakwatirana mwamtheradi ndi barbs, amene angachititse iwo zoipa mpaka kalekale, gnawing zipsepse.

nsomba Mpeni Iye wakonda kudya zakudya moyo; tizilombo, Tubifex, mwachangu nsomba zina, nyamayi, nkhanu kapena grubs. Angaperekedwe tating'ono ting'ono nyama. Ndi chakudya yokumba anazolowera monyinyirika, koma ndi ena khama kukwaniritsa zimenezi. Nthawi yabwino kudyetsa nsomba - madzulo.

Unamwali apteronotusy akafika zaka chimodzi mpaka zaka imodzi ndi theka. Pakuti spawning anasonkhana 2 amuna ndi 1 wamkazi. Spawning zambiri kumachitika pa madzi ndege opangidwa ndi mpope kutsitsi (makamaka zawo pa nthawi ino) m'mawa, maola mbanda kucha. Chonde akazi kungakhale kwa mazira 500. Mazirawa ndi ndi lalikulu, chikasu, slabokleykaya. Spawning akupezeka mphako pakati pa miyala, chikuni choyandama kapena zokongoletsa. Mphutsi kutuluka mazira patapita masiku awiri kapena atatu, ndipo atapita masiku 5-6 akhoza kale kusambira ndi kudya pa awo zomera pang'ono chabe. M'mwezi wachiwiri wa mwachangu akulimbikitsidwa kupereka okwanira m'misasa munthu, kapena iwo akhoza kutafuna pa peduncle caudal pa wina ndi mzake pa nkhondo.
