I keep and breed show standard guppies. I am lucky enough to be able to attend shows accross Europe, and further. I am also an international guppy judge. Life is good.
European Show Guppies are completely different to those that you would normally find in an aquatic shop, they would normally have originated in Singapore, Thailand or even Sri Lanka.
Typical Singapore Guppy
These 'normal' pet trade guppies do not compare with the quality of High Breed Guppies.
The two main features of these guppies that differentiate them from the European guppy is the dorsal fin and the tail fin.
European Blond Half Black Red
The dorsal fin is usually short and stubby in a pet shop guppy where as the High Breed guppy would have a dorsal that overlaps the tail and is full of colour.
The tail shape of the European Guppy is far superior to that of the pet shop guppy. Thirty years ago the shop guppy triangle tail was large and a reasonably true shape but now it seems that the tail size is reducing and the shape is hardly even recognisable as a triangle, this has developed because it is easier to keep and ship these mass produced guppies with high stocking levels.
The European high breed guppy has a true tail shape, indeed there are 12 different tail shapes. The standards of these 12 tail shapes are based upon those that originated in England in the 1950's and 60's and the guppies are bred to achieve the 'ideal guppy' as defined by the IKGH standards.
