About

The Tuxedo Blue Platy carries the tuxedo gene that causes the rear half of the body to be significantly darker than the front, creating a clean two-tone effect. In this blue variant the lighter front is a steel or sky blue, transitioning sharply to midnight blue at the mid-body.

This pattern is striking and consistent across individuals in a quality line, making it a popular choice for hobbyists who prefer a clean, defined aesthetic over the more variable multicolour strains. Females also carry the tuxedo pattern, which makes sexing straightforward.

A very hardy and adaptable fish, the Tuxedo Blue Platy is suitable for beginners and experienced hobbyists alike.
