As is the issue with some of the babies that are not as clear as others...I see left to right starting with the top row; girl girl boy boy, second row; boy girl boy. That's going on clarity of striping alone, except for the lower right hand boy. For some reason some pictures have shown up recently showing males missing their white spots. Anyone know why this might happen?
Best wishes with your babies. It will soon be obvious who is who, and as Rinda said I would encourage you to mark the ones who are most clearly autosexing for possible future breeders.
