I’m not sure, I got them as assorted peacocksWhat species are they? They might be too young to sex. Males and females look alike until they are old enough for the males to color.
The grey one is 2 inches, and the white one is 1 and a halfMore relevant to determining gender is what size are they? At this point the top photo looks very much female, bottom photo possibly male, could go either way if it's as small as it looks.
Welcome aboardFemale color right now but you'd need to wait until they mature to know.
