Terry Hewitt (Fish Ark Bracknell): Hi all, What I have found with this species, is, they are fairly hard to find in the first place, and when I did find them, the young always turned out to be females, even when I split them up and put them in different tanks, with different conditions\/temperature etc,  I got 100% females, but when I did get 3 males, to go with my 5 females, the young came thick and fast and I now have a thriving colony.
\nI have found, they need little or nothing extra, to other Xiphophorus species, it’s just what I find<\/p>\n
