The Goldfish (Carassius auratus)

Goldfish are native to the People's Republic of China, Taiwan, southern Manchuria, Korea, Japan, Hainan, and the Lena River of eastern Europe to the Amur Basin and the Tim and Poronai rivers of Sakhalin (Berg in Courtney et al., 1984).
Goldfish possess a long dorsal fin with 15 to 21 rays and a hard serrate spine at the origin of the dorsal and anal fins. Their Lateral line is complete, with 25-31 scales in a lateral series. Their pharyngeal teeth counts are: 0,4-4,0 (Robison and Buchanan, 1988; Page and Brooks, 1991).

Oranda (Carassius auratus)

The Red Oranda is one of several varieties of what is commonly known as the Goldfish; Carassius auratus auratus. Originally from parts of Asia, Japan, and China, Goldfish now enjoy worldwide distribution due to controlled breeding programs. The Red Oranda is a metallic-scaled fish. Resembling the Veil Tail varieties, the Red Oranda's distinction is in its color and the "hood" that covers its head. In the case of the Red Oranda, the entire body and hood are a bright red or orangish-red. All Goldfish are members of the carp group and generally quite hardy.
Oranda's, like Goldfish are omnivorous, and will eat all types of dried and live foods. Limit protein, however, to 30% of the diet. A Goldfish flake or pellet food will provide these fish with the proper nutrition.

Sarasa Comet (Carassius auratus)

These comets are a hardy fish originated in China. They have a bright red/silver-white coloration and a spectacular tail development. The Sarasa comets can grow up to 12" in length. They prefer foods of pellet or flaked form that do not exceed 30% protein. Minimum pond size recommended is 180 gallons. They like to eat the roots of plants and have been know to dig to get to them, so large rocks surrounding the plants are helpful in protecting them. The males have different features that the females in that they have a concave anal section and sometimes breeding spots on the head. Spawning can produce up to 1,000 eggs. The fry become visable in about six days. Feeding the fry with small live foods will enhance their color within about 8 months. Good water quality and adequate filtration play an important role in the health of these as well as all pond fish.

Shubunkins (Carassius auratus)

The Shubunkin, a type of single-tailed goldfish, is originally from China and over the years has been distributed world-wide. The Shubunkin differs from the wild Carp in that it lacks the barbells on the mouth area, the markings at the base of the scales, and the size. The Shubunkin is a hardy fish, and has a mottled pattern of white, black, and orange. It may also be called the Speckled or Harlequin Goldfish.
Shubunkin's, like Goldfish are omnivorous, and will eat all types of dried and live foods. Limit protein, however, to 30% of the diet. A Goldfish flake or pellet food will provide these fish with the proper nutrition.
