The picture of a telescope, shows excellent eye development, and finnage.Ĭ. Telescope eyes – eyes, which are mounted atop a cone-shaped protrusion on either side of the head. Goldfish have several different eye-types, as follows:ī. Common goldfish colors include the following: red, orange, white, black, blue, chocolate brown, yellow, red and white, black and red, black red and white, calico (a combination of colors usually including red, white, black and blue). Goldfish come in a number of distinct colors, including combinations of colors. Nacreous – A scale type which combines characteristics of the metallic and matte scale patterns, often in random proportions, causing a mixture of reflective and non-reflective scales on a fish. Matte – Scales which lack the reflective guanine layer, leading to a dull or non-reflective appearance.Ĭ. The shiny appearance is caused by the presence of guanine in the scale.ī. Metallic – Has a shiny, reflective appearance, much like a metal object, hence the name metallic. Three basic types of scalation occur in goldfish: metallic, matte, and nacreous.Ī. Listed below are basic goldfish characteristics, along with a line drawing of goldfish anatomy provided by Merlin Cunliffe. There are several additional fish, which could fit into these categories, such as Tosakin and Wakin, but these were not considered plentiful enough to recognize as a separate breed at that time.Ī general understanding of goldfish characteristics is helpful, before a detailed discussion of breed varieties is started. Double tail with dorsal fin, possessing either a fantail or Veil tail body shape Single tail with dorsal fin, and streamlined body shapeĢ. The body types recognized were as follows:īased on the four criteria listed above, the following varieties of goldfish were recognized in the U.S.ġ. The fourth criterion that was added later dealt with the basic body shape of the fish. The classification system that was developed differentiates fish into three broad categories, based on tail-fin and dorsal type. A few years later, we added a fourth classification type, which made identification easier. After much thought, we came up with three basic criteria, which could be used to categorize all types of goldfish. The identification process had to be simple and easy to follow. Our project was started to provide a way to identify, classify, and judge among the various types of goldfish commonly seen by hobbyists and entered in fish shows.
A few years ago, several folks were working on a goldfish standard project for the GFSA (Goldfish Society of America), and wanted a simple way to identify the seemingly endless varieties of goldfish.
