   This is an elegantly beautiful livebearer, named for the keel like scales along the ventral
   edge of the caudal peduncle. I have had this yellow/amber line with a blue sheen for
   nearly 10 years. This fish is originally from Costa Rica, Panama and Nicaragua.

   This is a peaceful fish that does well in a community tank. Always highly desired at fish
   conventions, it is not often seen in the hobby. In the wild they are insect eaters, and
   enjoy being fed fruit flies in combination with a quality dry food. They will eat most any
   live and dry foods. When breeding this fish you may find that they will produce heavily
   male or heavily female broods at first, but over time the ratios will even out. This line
   also rarely throws leucistic individuals that are a light amber with silver/ white eyes
   (not blue), but for me those mutations have all been male and infertile.

   They do best in slightly warmer water (74-82) with some movement, plants to hide in
   and regular water changes. The young are fairly small for a livebearer but easily
   identifiable from birth for their slender eel-like shape. Attempts to raise them with
   other fry (since they are easily identifiable) results in their getting picked on and
   eventually disappearing. Larger adults are generally fry eaters, and the young
   are best raised separately. More information Here.
