While goldfish have been kept as pets for hundreds of years, the tropical fish hobby owes its great success to the comical little tropical fish the Guppy – the first “tropical” fish to gain widespread popularity.  After more than half a century of cultivation, the Guppy is still the most popular tropical aquarium fish.  More than a few aquarists have been introduced to the hobby by a gift of guppies from a friend.  In his book, “Exotic Aquarium Fish”, Dr William T. Innes refers to the tropical fish Guppy as the “missionary fish” because it has made so many converts to the aquarium hobby.  But what could be unusual about a fish as common as the common guppy?

The Guppy has been introduced to so many places throughout the tropical America’s that it is not certain just what the original habitat of this fish was.  However, most scientists believe that the Guppy’s original home territory was Venezuela, Trinidad and the Guyana’s.  This tropical fish is extremely plentiful in these countries.  For instance, every drainage ditch in the city of Georgetown, Guyana teems with Guppies.

Credit for discovering the Guppy is generally given to the Reverend John Lechmere Guppy, who is supposed to have collected specimens in Trinidad in 1866.  Even this little bit of Guppy history is tropical fish guppyclouded by doubt.

This bit of Guppy lore goes something like this.  About 1860, an English naturalist, Lechmere Guppy, Sr., living in Trinidad, frequently send to the BritishMuseum collections of natural history tropical fish specimens.  Among some fish that he sent was a tiny, brightly colored little fish that was described as a new species and named, after him, Girardinus guppyi.  After it had enjoyed years of popularity as an aquarium fish, and had become known to aquarists by the specific name guppyi, someone discovered that, years earlier, the same fish had been described as Lebistes reticulates.  In the meantime guppyi had been shortened to guppy, and no matter what changes are made in tropical fish catalogues, books on aquaria, or labels on exhibition tanks, guppies will be guppies as long as the little fish retain their deserved popularity among fish fans.  There is another fish from Trinidad which has the official right to the name of Mr. Guppy.  This fish is Hemibrycon guppyi, but as it is a much larger tropical fish than the Lebistes reticulates, is rarely seen in aquariums due to its violent nature, additionally it is an egg-layer.  With this in mind, there is not the slightest danger of confusing the two very different fish which unofficially share the name guppyi.

Aquarium fish for backyard pondsGuppies, in spite of their tiny size, are useful citizens of whatever pond or stream they have been introduced to and inhabit. Specifically, one of their favorite foods is the “mosquito larvae”.   This tropical fish the Guppy is able to eat almost their total weight of “mosquito larvae” every day!  As, in nature, this little gem is always prolific; they are known in the West Indies as “million fish” since it is mathematically possible for a single pair to multiply and become a community of close to a million fish during a year of near perfect conditions.  The sum total of their efforts in mosquito control has made much of Florida inhabitable, as well as many other areas of the world.  The extent of their contribution is debated but they seem as desirable in nature as they are in the aquarium.tropical fish guppy

From the beginning of Guppy culture, it was noted that males showed great variety in fin shapes and colors.  No two wild male guppies were ever exactly alike.  Through the years guppy fanciers have carefully selected until there are now more guppy varieties than could possibly be described here.  Literally every color is seen on male guppies.  There is even one tropical fish variety, the golden guppy, in which both sexes are yellow all over.

feeder fish tropical fish guppySeveral guppy varieties are worth virtually nothing, yet are sold as feeder fish and still fulfill a valuable purpose to the aquarist. Some males have beautiful sword like extensions on their tails.  The extension may be on the top or the bottom.  It will come as no surprise that these are called swordtail guppies.  In another variety, there is a sword extending from both edges of the tail.  These are called lyre tails.  Still another variety produces males with an iridescent green netlike pattern over the tail fin and body.  These are Referred to as lace or snakeskin guppies.

The aristocrat of tropical fish guppy varieties is the veil tail guppy, prize specimens of which frequently sell for more than $100.00 a pair.  In the veil tail the tail has been developed into a broad triangle, sometimeshi breed guppyy tropical fish as long as the fish’s body.  The dorsal fin extends back like a long plume.  Veil tails come in many exquisite colors.

The king of guppy breeders was Henry Kaufman, of Trenton, New Jersey.  Mr. Kaufman’s veil tail guppies were known the world over as the finest money could buy.  Many of the strains available today were originated by his organization.  Kaufman won so many world championships, national and local contests with his tropical fish guppies that he retired from competition in 1966.

tropical fish guppyThe guppy has become so popular that there are national, international, and local guppy breeders and aquarium associations.  These organizations, much like rose garden societies and kennel clubs, exchange information, set standards for prize winning guppies, and sponsor tropical fish guppy contests to promote and encourage amateur participation in the competitive breeding world.

The root guppy or “original” may be plentiful, is referred to it as the “common” guppy.  This variety is sold very inexpensively as “feeder Fish” in many pet and tropical fish aquarium stores.  This variety had colorful males and drab gray females.  This is by far the heartiest variety for backyard summer ponds, and when the weather turns, guppy breedingthey will fade away into memory only to be replaced inexpensively the next spring.

The  tropical fish Guppy is referred to as the millions fish, because 6 females and 3 males can easily produce what seem like a million fish by the end of the summer, given the room to grow and the food to support such a colony.
