This is the second batch of fry my mollies have had and I have 14 females and no males. what am I doing wrong? I just heard that it maybe has something to do with the temp of the water. I keep mine at 77 degrease.
How many male and female adults do you have? I have heard that if you have more females than males in your tank, you will get more male fry, and if you have more adult males in your tank, you will get more female fry.
You likely will have about equal numbers of males and females once the fry have had a chance to develop their sexual characteristics. At 5 weeks, you can't tell on most of these guys and all look female but I am not concerned about that. When they are around 2 to 3 months old I expect them to sex out about equally.
Actually a close inspection of the picture leads me to think I have at last 4 that I am fairly sure will show male characteristics in less than 2 more weeks. Lots of the others probably will too when they develop enough.
