I have found (although it may be pure coincidence) that that male fry "show their stripes" more than females. At just over an inch they are all silver with faint vertical barring that will get darker if they are stressed or spooked, however, I separated the ones with more barring from the ones with less, and at just over 2 inches only the ones with the barring are showing blue in their faces. This leads me to believe that the males show more barring than females at a young age. Once the males fully color up the vertical barring is all but impossible to see, whereas the females stay silver and you can see it throughout their lives at least to some extent. Anyone else ever notice this or have any idea what I'm talking about? Do you think it's true or just coincidence?
