Goldfish
Family: Cyprinidae
Scientific nameCarassius auratus var.
Feed: pellets, Flake, specilised goldfish foods, Greens
Tank Size: 15 gal first fish, 10 gal for each additional specimin for them to reach full size.
Temperatures: 65°-72° F (18°-22° C).
Size:15 cm (6 inches).
Care and feeding:
Since they are omnivorous, the Goldfish will generally eat all kinds of fresh, frozen, and flake foods. To keep a good balance give them a high quality flake food everyday. Feed brine shrimp (either live or frozen), blood worms, Daphnia, or tubifex worms as a treat.
It is usually better to feed freeze-dried foods as opposed to live foods to avoid parasites and bacterial infections that could be present in live foods.
Distribution:
Domesticated goldfish are distributed world-wide but originally came from China.
Social Behaviors:
Goldfish are very social animals and thrive in same species groups.They are great scavengers as well. It is really not necessary to add other scavengers or other bottom feeders to the aquarium when you have goldfish.
Sexual Differences:
Although is it impossible to sex Goldfish when they are young and not in breeding season, the male is usually smaller and more slender that the female. In the breeding season the male has white prickles, called breeding tubercles, on its gill covers and head. Seen from above the female will have a fatter appearance if she is carrying eggs. male goldfish will activly chase any females during breeding season wether in a tank or not
Water Region: Top, Middle, Bottom:
These fish will swim in all areas of the aquarium.
Breeding/Reproduction:
Goldfish are egg layers that spawn readily in the right conditions.
Fantail Goldfish
The distinguishing characteristic of the Fantail Goldfish is its split or double caudal (tail) fin. The tail fin is medium length and is slightly forked as well. These fish are bred for showing and good specimens have complete division of the tails which are closer together at the top than at the bottom. Good show specimens also have a double anal fin with complete separation!
Fantails are available as metallic, nacreous, or matt scale types (reddish orange, speckled, or whitish). The Ryukin Goldfish is a Japanese version with a highly curved back and a wider caudal fin than the Fantail. Both Ryukin Goldfish and Fantail Goldfish are recommended for the beginner.
The Fantail Goldfish is one of the few fancy goldfish, along with the Black Moor*, the Ryukin*, and the Shubunkin*, that are considered suitable for beginners and can be kept at temperatures close to freezing. Their hardiness and ability to live at colder temperatures makes them ideal for outdoor ponds.
Black Moor Goldfish
The Black Moor Goldfish is basically a black version of the Telescope Goldfish, though the eyes usually don't protrude as far as the Telescope.

Ryukin
The Ryukin is a variety of fancy goldfish sometimes considered a Japanese version of the Fantail Goldfish. They differ in that they have an extremely high back and a wider caudal fin than the fantail.
The most notable feature of the Ryukin is a hump in its back immediately behind its head. The higher and more pronounced the hump is, the better the quality of Ryukin. The Ryukin's body is typically triangular in shape with a fat belly and a deep body which is almost as deep as it is long. The head of a Ryukin is more pointed than that of other varieties of goldfish.
Ryukins have two evenly paired anal, ventral and pectoral fins. Caudal or anal fins may be doubled. The caudal fin shape may be longfinned, short tailed, ribbon, or butterfly, the last one being particularly attractive when viewed from above. Short tailed ryukins and some ryukins cross-bred with fantails are called "man-yu's".
Ryukin Goldfish are relativly hardy for fancy goldfish and are recommended as a beginner fish.
