is it true that large silver arowana's are doomed to have DE (drop eye) eventually? I have a 16" silver aro with one eye DE and the other isn't but with time will the good eye get DE? does DE worsen with age? and in your opinion do you think silver arowana with DE look better or more natural than ones that don't have it? When I was a kid I use to see Chinese restaurants with big tanks and arowana's that always had DE so it almost seems strange to see one without DE.
