Goldfish Scale Types

Scale types of goldfish are treated mainly for the definition but can also lead to terminology. The scales of goldfish are typically cycloid which are round and exhibits different array of color patterns, especially scale orientation based on the fish that was born with this expression. There are a few main variants of scale type, and two that are the subcategory of one.

1: Metallic

Metallic is an abundant scale type found in most goldfish breeds today. Typically the metallic scales are visually appear to shine from the light it reflects due to present concentrations of guanine, which is not a chromatophore. Except for melanopores, erythrophores and xanthophores exhibit guanine luster in metallic and nacreous fish. Metallic scales are thought to be the basis of all known scale types.

3: Matte(Transparent)

This scale type is the least seen though not seldom. It occurs when there are no reflective layers of guanine in the body scales, making it appear transparent including the colors. The blue-like coloring in mattes are black at the base of the scale layer. Mattes are often seen from nacreous spawns due to heterozygous parents. Matte along with metallic are homozygous.

2: Nacreous

Any goldfish with this scale type are not only transparent but are reflective due to scales being metallic and matte over the body. Shubunkins often inhibit this scale type. This particular type is heterozygous, which adds more different alleles from a particular allele.

Other Notes

The name of a goldfish reflects to not only the breed and the pattern of colors, but also along with the scale type included. Some names can be used for a multitude of scale typing.

Metallic forms

1. Sarasa: the name of pattern is only used for comets with red and white scales, much like a kohaku.

2. Panda: the name of a pattern in goldfish with black and white scales

3. Tricolor: it is of any goldfish exhibiting black, red and white scales.

4.

Matte Forms

1. Pinkie: this pattern lacks any color under its scales and above, making the skin and flesh visible. Pinkies usually have black eyes

Nacreous Forms

1. Calico: An original pattern of coloration containing array of red/yellow/orange, black/blue and white scales. Shubunkins commonly show calico on every individual, but it's possible for a shubunkin to not have calico whereas the scales are left nacreous(example: Sakura).

2. Kirin: A type of calico, the fish has prominently deep blue at the top to half of the body depth, while orange/red and black colors dapples all around, whereas white stays at the lower half. Oher Kirin goldfish ccan 3. Tiger

Other forms:

Blue based: This pattern exhibits in matte and nacreous fish that has black depth at the top proportion of the body appearing blue for its namesake.

Sakura: This pattern exhibits in matte and nacreous fish that has red and white patterns.
