Breeding and Showing Guppies

Judging The Delta Male Guppy to IFGA Standards

By Bryan Chin and Stan Shubel

Introduction

This article focuses on judging the color and shape of IFGA standard delta guppy males. I (Bryan) chose the best pictures I had of guppies that could clearly show the color and shape. These were then sent to Stan to point the color of these since this is the most difficult part of judging. For shape judging I superimposed proportion outlines over the photos and then pointed the fish. To further judge the guppies the body size point estimate is given from what I remember (the guppies are mine). From the body size, tail and dorsal size point can be estimated. Condition, deportment and symmetry are pointed by Stan as they appeared in the photo. All points were then sent to Stan for review/adjustments and edits. All the points are totaled to show their standings.

Be sure to reference the IFGA Judging Standard available to IFGA members on the www.ifga.org website to better understand how these guppies are judged. Pointing IFGA guppies is challenging and is well known by those who take the visual judging test. This article can help those working towards being a judge, and picking the right males for breeding and competition.

Judging Color

Color is broken down into density and intensity. Density is the amount of color that adheres to the color class it is entered in. Intensity is the brightness of the color that adheres to the color class. For example if a green guppy only has 50% of the tail that is green and other half is black is can only have half of the points for density.  The intensity of color can only be pointed for the amount of color that is green in the tail.

Judging the Shape

Outlines were used on each guppy to help show how close the shape proportion requirements are met. The illustration below shows the proportions.

Summary

Below is a summary of the points. To further judge the guppies the body size point estimate is given from what I remember (the guppies are mine). From the body size, tail and dorsal size point can be estimated. Condition, deportment and symmetry are pointed in the table below as they appeared in the photo.
