For regular zebra danios it is possible to tell the difference between males and females. Females have blue and silver stripes and males have blue and gold stripes, and the females usually have more of a rounded bodyshape. Other than body shape I'm not certain how you determine the sex of glofish.
During spawning they scatter their eggs. As with regular zebra danios, you should place marbles in the bottom of the breeding tank so that the parents won't be able to eat the eggs. You should also have plants in your spawning tank. After spawning is complete remove the parents from the tank and place them back into the regular aquarium.
i have learned by observing how to tell between male and female it's actually quit easy
MALE:slender body a Little bit bigger wavier fins.
FEMALE: chubby smaller fins by just a bit and you know for sure when u catch them breeding/spawning.
PS. i don't have a breeder tank they just do it in the regular tank and i am not trying to breed them they do it them self's i think they be in love because he doesn't go near the other 2 females in the tank
