Young Males

at what age can you start to tell male and female bettas apart

 

[helterskelter]

When the fins develop!!!!

Or they develop better colour's to the females.
Their is no rules like at 90 days the males will develop, what you see is a defo male showing against all the other fry, take him out and the next day or two your see another, then another, and then you start to get 3-4 a day developing, and can go on for 3-4 week some times longer depending on how many you have.
