Goldfish originally came from China. Goldfish differ from Koi in that goldfish grow to a maximum of
about 12 inches whereas Koi will grow to more than 2 feet long. Also,
goldfish don't have barbs at their mouth.
Main Categories of Goldfish:
Pond Comets - include Common Goldfish, Comets, Sarasas and
Shubunkins. They have a single tail fin and a dorsal fin. Single tailed goldfish are generally hardier but require more space
than fancy varieties, so they are often better suited to ponds. Commons and comets are very similar with the exception
of the tail shape, with comets having long scissor-shaped tail fins. Both are most commonly
seen in orange, bronze, white, orange and white, or red and white (also known as sarasa).
Shubunkins have calico colors.
Fantails - include Common Fantails, Black Moors, Ryukins and Orandas.
They have forked tails and a dorsal fin. Orandas have a red cap on their forehead.
Ryukins have a pointed nose
and tall hump on their back, which gives a notched appearance to their profile.
Fancy - include Fancy Fantails, Ranchus, Lionheads, Bubble Eyes, Telescopes, Pearlscales,
Celestials, Jikins and Wakins. Most are related to
fantails. Fancy Fantails have flowing long tails. Ranchus are
similar to Orandas, but have no dorsal fin and an extreme arch to
their back. The lionhead is a variation of the ranchu. Bubble Eyes
have eyes set in large "bubbles", while Telescopes have eyes that
extend out from their bodies. Celestials have eyes that face up.
Pearlscales have round bodies with scales like a golfball. Jikins and
Wakins are similar to comets, but have double anal and double caudal
fins. Jikins are bred to be only white with red lips and fins.
Goldfish are extremely hardy and can survive outdoors in freezing conditions
provided that they have a fresh supply of oxygen through the ice. They
eat a variety of flake and pellet food, as well as
plant material. Breeding occurs in temperatures around 75 degrees
Fahrenheit and can result in hundreds of eggs. The fry hatch in five to
Although goldfish are predominantly an outdoor cold water species, they
can tolerate warm temperatures and aquarium life easily. Fancy goldfish
generally are not good pond fish because they are more sensitive to cold and canít compete
other types of goldfish for food.
Goldfish are incredibly messy fish that need large tanks, powerful filtration, and regular
maintenance. A bowl is not a good home for these fish. The 1 gallon per inch of fish guideline does not
apply to goldfish, even if you measure the adult size since much of their size is not in length,
but in width too. A good suggested minimum for small fancy goldfish is 10 gallons each, and single
tailed goldfish 15 gallons each, but bigger is always better for these fish.
Many more breeds are appearing, so keep on the look out.

Goldfish are peaceful fish. Comets should not be
combined with fancy goldfish, as the fancy goldfish will have trouble competing
for food. If goldfish are combined with other freshwater tropical fish, it is best to
limit this to catfish. Fancy Goldfish can also be combined with danios,
ottos, white clouds, barbs, kuhli loaches and
