I’ve recently been searching on the web about methods of yielding more male/female Guppies from batches of fry. I’ve read that softer water with lower PH yields more females, harder water with higher PH yields more males. I’ve read that even the temperature can affect the ratio of sexes. Has anyone tested these methods and can say they are true? Or is this all a myth? I would like more males in my batches when the time comes, since they are so colourful and mesmerising to look at!
