In the hobby since the early 1900s, the Guppy is one of the best known and most popular aquarium fishes of all time. It is an adaptable, hardy fish whose inherent genetic variability has been exploited over the years to produce a bewildering array of fin and color permutations. As a result, the original short-finned wild type of the species is hardly ever seen, except in the aquaria of specialist livebearer enthusiasts. Endler’s Livebearer is a particularly beautiful wild form.
