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.
This section covers a group of four families, in which many of the species produce live young. The family Poeciliidae contains the most popular aquarium fish that produce live young. Many beginners start with the guppy (Poecilia reticulata), progressing to swordtails such as Xiphophorus helleri. One major reason for the popularity of the group – […]

[Ebook] Encyclopedia of Aquarium & Pond Fish – Introduction to Freshwater Fish – Breeding – Fish genetics
The science of genetics is concerned with the way in which characteristics pass from one generation to the next. The characteristics of all living organisms, including fish, are contained in the genes, which are carried on rodlike structures called chromosomes, present within the nucleus of every living cell in the body.

Once the aquarium is fully prepared and you are certain that everything is functioning properly, you can start to introduce the fish. Although suppliers can ship stock to you, it is probably best to visit a local store, especially when starting out, so that you can see the fish firsthand. Ask experienced aquarists to recommend a store—ideally one that belongs to a recognized trade association. Such bodies run specialized training courses for staff, so you are more likely to receive genuine, professional advice.
Wild guppies are small fishes; the males have splashes of colour on their bodies and the females are a dull grey/brown with a dark triangular “gravid spot” near their vent. These wild forms bear little resemblance to the man-made guppies with which we are familiar today. Indeed, one could be forgiven for thinking that the latter are an entirely different fish.
Some of you may be tempted to keep Cyprinus carpio (Koi Carp) in an aquarium and we would like to advise against this. Koi are potentially large fishes best housed in large purpose-built ponds with powerful filtration systems.
