Okay so here is the story, I got Max and Ruby on the 21 of January, and then got 3 more females, I had them in a 10 gallon tank, started having issues lost the 3 females so I was back to Max and Ruby, Got a 46 gallon tank with some guppys, cycled that tank and moved Max and Ruby in, alls good in the tank lots of Guppy babys, I only remove the babies to another tank due to my fish aint eating them anyway so I will raise them and just keep the ones I want, when I tore down the 10 gallon I found a platy fry, maybe about a day old, that was the 17th of February, nothing so far since then, and like I said my babies swim right in the total view of the adults and they do nothing against the babies in fact I have had 6 1-week old molly fry in the main tank and they are now 3 weeks old, so its now been 5 weeks is she ever going to have her babies, I know I should have more female platys to the male but the last female I got died 3 days after I got her and she was quite active when I got her. My PH is 7.0, Ammonia is 0, Nitrite 0, Nitrate 5.0, so why hasn't she had babies.
