Common goldfish - online puzzles

The common goldfish, also known as a feeder goldfish, is a breed of goldfish with no other differences from their ancestors other than their color. Goldfish are a form of domesticated wild carp and are a close relative of koi. Most varieties of fancy goldfish were derived from this simple breed. Common goldfish come in a variety of colors including red, orange, yellow, white, black, and calico goldfish, with the most common variation being orange (combined with its shiny fins, hence the name ). Sometimes, color may be an indication of the fish ’s health status.
