I hold a shipment of beta fry, what age must they be past i enjoy to seperate adjectives?
fry are 2 weeks old
Once they started swimming, you may separate them cause they'll know how to eat on their own.
If you never separate them, the males will not row because they grew up together, this is the only way male bettas can coexist. Once you separate them even for 5 second, it's over, the males may think it's a rival male and fight it's own sibling. But across the world people separate them at about 3-4 months.
Answers: Anywhere between 6-8 weeks really, sometimes longer. It will depend on your fry. As soon as some start chasing and nipping it's time to start jarring! Have a read through the links below.
