Vodokras rana
Frog watercres, inoa ʻepekema Hydrocharis morsus-ranae. He kanaka maoli ka mea kanu i ʻEulopa a me nā ʻāpana o Asia. Ke ulu nei ia i loko o nā wai paʻa, e like me nā loko a me nā puʻu, a me nā wai mālie o nā kahawai. Ua hoʻokomo ʻia i ʻAmelika ʻĀkau i ka makahiki 1930. Ma hope o ka laha koke ʻana i nā kino wai o ka ʻāina, ua hoʻomaka ʻo ia e hoʻoweliweli i nā mea olaola kūloko. Hoʻohana nui ʻia ia i loko o nā loko, akā ʻoi aku ka liʻiliʻi o ka mea maʻamau i nā aquaristics, ʻoi aku ka nui ma nā aquarium biotope.
ʻO waho e like me nā lilia wai liʻiliʻi. He oval ke ʻano o nā lau lau, ma kahi o 6 cm ke anawaena, paʻa i ka hoʻopā ʻana, me kahi notch hohonu ma kahi o ka hoʻopili petiole. Aia nā lau i kahi kūlana, i hōʻiliʻili ʻia i loko o kahi rosette mai ke kumu kahi e ulu ai kahi puʻupuʻu o lalo o ka wai, ma ke ʻano he kānāwai, ʻaʻole lākou e hiki i lalo. I ka wā mahana, pua ia me nā pua keʻokeʻo liʻiliʻi me ʻekolu petals.
ʻO nā kūlana ulu maikaʻi i manaʻo ʻia he wai mahana, ʻakika iki, palupalu (pH a me dGH) wai me kahi kiʻekiʻe o ka mālamalama. ʻAʻole pili ka minerale o ka lepo. I loko o kahi aquarium makua a i ʻole loko iʻa me kahi kaiaola i hoʻokumu ʻia, ʻaʻole koi ʻia ka hoʻokomo ʻana o ka lole luna. He mea pono e hoʻomanaʻo i loko o kahi liʻiliʻi liʻiliʻi o ka wai, ʻo Frog Vodokras, i ka wā e ulu ana, e kahe koke i ka ʻili āpau. I loko o kahi aquarium, hiki i kēia ke alakaʻi i ka hoʻopau ʻana i ka hoʻololi ʻana i ke kinoea a me ka wilting o nā mea kanu ʻē aʻe, e lilo ana i mea lawa ʻole.
