How old will Platy fry have to be before you can see if they are males or females? Other Pet Discussions
Are the fry 'fully formed' when they are born, or do they develop the visible differences as they grow? They're about 1/2 inch long now, and getting nicely colored.I need to see for sure which are which, because my friend wants only the males in his tank, and he's waiting for them. Meanwhile I was wondering, if they are born male/female formed, or if it develops later, like going thru puberty?
