Hi, as a big surprise I woke up 3 days ago and found hundreds of eggs on the flat stone.. I ran to this page and read all your advice, separate them from the main tank, put them in a 30x20x20 cm plastic tank, air stone under the flat rock , methlyn blue etc... Success ! Some hours ago the first ones started to hatch. So i know i don't need to feed them for a couple of days but how long can i keep them in this plastic bowl? There is no filtering system in there, just an air stone and the water started to smell strong. I ve got a second tank with an external filter which i can prepare for them but what if they get sucked up by the filter..? Shall i wait for all of them to hatch or start to carry the tiny ones which hatched already to the other tank? Thank you..
