       Introduced to the hobby by Rusty Wessel around 2011,
      this large and colorful population is beginning to
      reveal itself to hobbyists. This is a very hardy and
      prolific swordtail. Like other larger swords, it will
      take 6-7 months before it will begin to breed. With a
      large tank and heavy feeding, occasional males will
      exceed 6 inches, surpassing both the X. montezumae
      and even the X. mayae in length. When well fed they
      do not tend to eat their young, though young are best
      removed as soon as they are seen and raised separately.
