    I need help sexing my Rainbowfish. I'm under the impression that I have 2 males and 2 females. Am I correct?

    Hi and welcome to the forum :)

    male Melanotaenia boesemani have blue/ purple on the front half of their body, females don't. So if they show any blue on their face, they are males.

    Females are primarily silver with a few pale horizontal lines but look completely different to males when mature.

    Basically, blue & yellow are males, silver are females.

    The fish in all 4 of your pictures are males.
