Calico group: The Calico type of goldfish can have different kinds of patterns of either reflective scales, matt scales because of the absence of the guanine layer in their skin and nacreous scales when the guanine layer is partly present. The common color effects of the goldfish with matt scales depending on the color pigments that are present are pink; blue and colors like violet, gray and brown.
