JMiller2020 Posted February 27, 2022 Share Posted February 27, 2022 For some reason all my live bearers have only had females. Not even 1 male. Guppies,platies,mollies. Any guesses . I'm talking hundreds of babies all grown up and many generations all females . Crazy Link to comment Share on other sites More sharing options...
Minanora Posted February 27, 2022 Share Posted February 27, 2022 Maybe temperature? 1 Link to comment Share on other sites More sharing options...
PineSong Posted February 28, 2022 Share Posted February 28, 2022 Even the ones who are more than three months old are all female? I've had some platies develop gonopodium in month 4, but *I think* all my guppies have developed theirs before month 4. It seems crazy that they would all be female. 3 Link to comment Share on other sites More sharing options...
Cinnebuns Posted February 28, 2022 Share Posted February 28, 2022 Temp can effect sex of fry. Lower = more females and higher = more males. I however would caution against cranking the heat up too much. What you get in more males you also sacrifice in their life span. Higher temps will shorten their life span. But maybe try a degree or 2 higher. 1 Link to comment Share on other sites More sharing options...
