Broadtail Telescope

Telescope- Broadtail


The telescope eye has an origin in Asia over 200 years ago. The protruding eyes are variable, but matched on individual fish. Initially Broadtail Moors were only black in color. Today multiple color varieties are common. English Broadtail Moors have been bred in North America for decades, Linnemeyer and Sims-Shonka lines dominate the line breeding area.

Breed Development

The broadtail telescope is defined by three characteristics;

1. The presence of telescope eyes

2. A tall upright dorsal fin and the caudal fin having both significant length, breadth and the caudal trailing edge squared.

3. A single dorsal fin with all other fins paired.

Color; any and all colors and combination including black (moor), red, white, chocolate, blue, purple, bicolors etc.

Critical Features:

  • Body shape oval with no presence of a hump. The curvature of the top and bottom roughly equal.
  • Symmetrical telescope eyes, proportionate to the size of the fish. Eyes to also be symmetrical in direction of gaze, either to the side or slightly forward.
  • Body depth at least 2/3 -3/4 the length.
  • Tail split from 2/3 to 100%
  • Tail length ¾ to 1 ½ the body length depending on the age of the fish.
  • Tail margin well squared with no sign of forking. Ruffling is acceptable.
  • Anal fins paired and similar
  • When viewed from behind, a tail spread from 45-90 degrees.
  • A tall upright dorsal fin, at least as tall as the body is deep.

Key Deductions:

  • Twisted tail lobes, bent leading rays of caudal fins

or any lack of symmetry in lobes.

  • Forking in tail
  • The presence of a ryukin hump
  • Drooping of tail or other signs or peduncle weakness.
  • Twisted pectoral fins.
  • A dorsal fins that bends significantly or folds well to either side at rest.
  • Telescope eyes lacking, disproportionate or asymmetrical.
  • Bottom sitting, head standing or any other deportment issue.

Fin Development and shape*

Fin Development

Dorsal fin upright and erect (slight bending allowed) and tall.

Tail fins well matched, fluid, squared, held well, with split. Spread between 45-90 degrees.

Pectoral fins straight.

Anal fins paired and matched.

All fins well colored, translucent fins allowed.

Perfection Goal in points to the left 30
Dorsal Fin
Dorsal fin not fully erect, or folds to either side. Deduct 5-10
Dorsal fin has a rip, tear or an edge that abnormal Deduct 5-10
Tail Fin

Tail fins are matched and 2/3 to 100% split, squared, fluid, lead rays straight, but not stiff. Tail held well, with significant spread between top and bottom rays.

Perfection Goal
Tail spread greater than 90 degrees (Too flat) or any forking in tail. Any twists or bends. Asymmetrical. Tail drooping. Deduct 5-10
Tears in fin. Signs of wear. Poor color. Deduct 5-10
Pectoral Fin

Pectoral fins are visible from above, matched and are straight or cup-shaped

Perfection Goal
Pectoral fins are twisted or corkscrew in appearance Deduct 2-5
Fins are not visible from above Deduct 5-10
Anal Fin

Two anal fins that are similar in appearance

Perfection Goal
One anal fin Deduct 10
Anal fin protrudes beyond outside tail base Deduct 5, if it detracts from overall deportment
  • Maximum score is 30 points for the above section, each subsection suggests a possible deduction. The remainder of the tables describe a score for that area.

Body Shape

Body shape is deep and egg shaped 25
Body shape is too short 15-20
Body shape is elongated, perhaps too thin 15-20

Head shape, telescope eye symmetry & proportionality

Head is slightly pointed, like a Veiltail or Fantail

Eyes Match and there is no damage even though the fish may be blind. Head is in proportion to body, older fish ( OYA) may have very large eyes

Head is rounded, mouth crooked or turned down, eyes do no match 15-20
Head is over or undersized, face slightly twisted to one side, 1-15

Overall Condition

Color is bright and fish swims gracefully, judge may stimulate gently 10
Fish is resting on bottom 5
Color is faded, and / or fins not brilliant 0-5

Deportment (top and side)

Fish is balanced, tail is hanging in a balanced fashion 10
Fish lists in any direction 0-5
Head or tail stander 0-5
