I have a two fish container containing Adult black mollies, red platy, red eyed sword tail, balloon mollies and fancy tail guppies. at month of January red platies gave birth 30 frys, then february additional 15 frys and 20 frys of cobra guppies, and March, black mollies gave birth 25 frys and 20 frys of cobra guppies. these are estimations. estimated totals are 120 frys. estimated death is 15. I mixed the frys all in one container with a sponge filter. at month of april and may I gained nothing. but I find 3 or 2 sometimes in the adult tank. I suspected that adult fish eats the babies because the adult are mixed and don't have the proper way of breeding. please help me the proper way of breeding small livebearers to maximize my production of these fish. and sorry for my poor English.. I will be very2x thankfull for the help and Information I can get.
