IKGH international standard for guppy breeding 2004

At guppy shows all over Europe the guppies are judged by the european standard. The following is a shortened version of this standard. We do not explain here how to count the points, merely mention what the ideal standard-forms should look like.

1. Veiltail

  1. The caudal fin should have the shape of an isosceles triangle of 45 degrees coming off the peduncle.
  2. The ideal length is 10/10 of the body length.
  3. The edges are straight and even, and the corners may be slightly rounded.
  4. The slim dorsal fin raises steeply upwards at first, then ends pointed at the end of the first third of the dorsal fin.

2. Triangletail (Delta tail)

  1. The caudal fin should have the shape of a triangle having 70 degrees coming off the peduncle.
  2. Its length corresponds to 8/10 of the body length.
  3. The edges are straight and even and the corners can be slightly rounded.
  4. The dorsal fin raises steeply upwards at first. It is wide and ends at the end of the first third of the dorsal fin.

3. Fantail

  1. The caudal fin has gently curving upper and lower edges. The broadest part of the tail must be at 3/4 of its length.
  2. The rear edge is concave and its length corresponds to 8/10 of the body length, it may not be less than 5/10 of the total body-length.
  3. The width of the caudal fin should be 3/4 of its length.
  4. The dorsal fin is rounded and reaches the end of the first third of the dorsal fin.

4. Scarftail

  1. The caudal fin has a rectangular shape and its length corresponds to 8/10 of the body length.
  2. The width of the caudal fin is 4/10 of the body length.
  3. The frontal part of the fin is rounded.
  4. The minimum length is 6/10 of the body length. The minimun width corresponds to the body height.
  5. The slim dorsal fin raises steeply upwards at first, and has a pointed edge, extending to the end of the first third of the dorsal fin.

5. Double swordtail

  1. The caudal fin has an oval basic shape with swordshaped extensions of the upper and lower fin rays.
  2. The length of the swords corresponds to 10/10 of the total body length.
  3. The outer edges form an angle of 30 degrees or more.
  4. The part between the swords may be colourless and reach maximum 4/10 of the body length.
  5. The slim dorsal fin raises steeply upwards at first, and then ends pointed at the end of the first third of the dorsal fin.

6. Top swordtail

  1. The caudal fin has an oval basic shape with a swordshaped extension of the upper fin rays.
  2. The length of the sword corresponds to the body length and the sword comes off the body axis at an 15 degree angle, or stays parallel to the body axis.
  3. The basic oval part between the swords of the caudal fin can be colourless and reach a maximum length at 4/10 of the body length.
  4. The slim dorsal fin raises steeply upwards at first, and ends pointed at the end of the first third of the dorsal fin.

7. Bottom swordtail

  1. The caudal fin has an oval basic shape, with a swordshaped extension of the lower fin rays.
  2. The length of the sword corresponds to the body length and the sword comes off the body axis at an 15 degree angle to the body axis.
  3. The basic oval part of the caudal fin may be colourless and reach a maximum length at 4/10 of the body length.
  4. The slim dorsal fin raises steeply upwards at first, and ends pointed at the end of the first third of the dorsal fin.

8. Lyretail

  1. The caudal fin has the shape of a lyre.
  2. The basic shape of the fin is round and should not exceed 4/10 of the body length.
  3. The outer fin rays correspond to 8/10 of the body length and the tips are noticeable bent directing away from the body.
  4. The dorsal fin raises steeply upwards at first, and reach, with a slightly upbent tip, the end of the first third of the dorsal fin.

9. Cofertail

  1. The shape of the caudal fin looks like a mining spade.
  2. The upper and lower fin edges first draw away from the body, then go parallel.
  3. Its length corresponds to half of the body length. The hight reaches 8/10 of the fin length.
  4. The dorsal fin is pointed and ends between the beginning and the end of the first third of the dorsal fin.

10. Speartail

  1. The caudal fin has the shape of a spearhead.
  2. Its length is 8/10 of the body length, the hight reaches 8/10 of the fin length.
  3. The dorsal fin raises steeply upwards at first, and reaches with a slightly upbent tip the end of the first third of the dorsal fin.

11. Roundtail

  1. The caudal fin is round with a diameter of 5/10 of the body length.
  2. The dorsal fin is rounded and reaches the end of the first third of the dorsal fin.

12. Pintail

  1. The basic caudal shape is round with a diameter of 4/10 of the body length. The central fin rays are extended to a pin, and correspond to 10/10 of the body length.
  2. The slim dorsal fin raises steeply upwards at first, and ends pointed at the end of the first third of the dorsal fin.
