The Goldfish of today originates from wild Asian carps, and all the different Goldfish variations are considered to be the same species: Carassius auratus auratus. The Goldfish was one of the first fish species kept in ponds by man. In China, wild caught carps were kept in outdoor ponds as ornamental fishes and selectively bred until the eventually turned into the first type of goldfish. The ancestor of our modern goldfish is believed to be the Crucian Carp, Carassius carassius. You can find a wide range of different goldfish types, commonly divided into four main groups. The first group consists of the so called “Ce goldfish” or “Grass goldfish”, the second group contains the fancy “Wen goldfish”, the third group is where you find “Dragon Eye goldfish” with large and protruding eyes, and the fourth group is made up by the “Egg g pure acai berry oldfish” that lacks a dorsal fin. Keeping goldfish in ponds is still very popular, but goldfish are also kept in aquariums. Some of the fancy goldfishes have anatomical features that make life in pond risky for them. They might for instance have a hard time catching food since their eyes are deformed. When you keep goldfish in an aquarium, it is easier for you to make sure that the fish really eats. Ce goldfish / Grass goldfishIn this group, you will find the original type of goldfish. They are quite similar to their wild ancestors and do not have any fancy features. One of the biggest differences between a wild Crucian Carp and a Goldfish from this group is the coloration. Wild carps need a camouflaging coloration to survive, and mutations that cause unusual color variations are not common since those fishes rapidly become eaten.
