Adult males show a stunning deep metallic blue with silver flecks.  Females are silver-blue showing black vertical bars.  Juveniles are silver with back vertical bars.  Males will start to show the blue colour at around 2½ inches and will start to get the silver flecks at about 4 inches in size.

I have found these fish to be peaceful in my 6 foot community tank, but to be aggressive in breeding, beating up the females and on occasion killing them.
