Hi, of the juvenile multies I got from Lisa the two largest are obviously the ones I see the most. One is slightly smaller than the other but it is the smaller that has begun getting stripes now while the larger one is still a solid silver. What are the chances that this one will be female and the other male? Would it be the female that gets stripes at a smaller size due to the smaller adult size? Just wondering really what this might signify, if anything!
