Xiphophorus mayae, Rio Bellaire Videos


This is a big, muscular swordtail with intense horizontal red stripes, and the males posses
a long sword. Well behaved, they can be shy . Males will establish dominance with one
another, but their conflicts are minimal. As can be seen here, the females get quite large.

When comfortable, this is one sword that does not need to swim around the tank just
to expend energy as many other swordtails will do. Check out the males that enter
about 1/3rd into the video to get an idea of the full sword length for this species.




This is the same tank as the second video, and the same fish, but they are 9 mos. older, and the
largest ones here are probably as large as an X. mayae is going to get in a 40 gallon breeder
aquarium. The redder male with the orange sword is just a little over 5.5 inches. These are a
husky, beautiful fish.

    This video looks at the care and behavior of the X. mayae, discovered in 2002 and considered 
    to  be the world's largest swordtail. Questions include how best to determine proper livebearer
    male to female ratios for the greatest production of fry.


This recently identified swordtail (2002) is highly desired for its size, its intense color and majestic
appearance. Thicker in body than the helleri, it also sports a very long sword. This is a mellow,
almost shy community fish, and the males do not need to dominate and spar with their tankmates,
as many swords do. They also, as a rule, do not eat their fry.
