Interesting Information about Goldfish
The Goldfish (Carassius

usually the first experience most fish keepers will have with an
aquarium fish! There are
many types of Gold fish available and
they come in a variety of colors and sizes. Some have features
such as Split Tails, Dorsal Fins, Bubble Eyes and Long Fins but
they all originated from a species of Wild Carp
(Carassius auratus) native
to East Asia. Goldfish can be keep indoors in a coldwater
aquarium or alternatively can be kept in an outdoor pond.
Goldfish are an ideal starter fish and make a perfect first pet
for a young child. They require very little care and are
extremely hardy. Common Goldfish, Comets and Shubunkins are the
hardiest varieties and are the recommended choice for the
beginner. Did you know that a goldfish can live for up to ten
years? Remember the 3 second goldfish memory joke? There is a
myth that goldfish have a memory span of just three seconds,
recent research has proven this to be inaccurate and scientists

five months!

the sex of a Goldfish?
The males and females of many fish species have different colors
or different shaped bodies. But there are also other fish
species where there is no visible difference. Its sometimes
tricky being an ichthyologist!
Facts about Fish Species - Why are Goldfish slimy?
Goldfish secrete a type of mucus, or slime, from their skin.
This slime provides protection against parasites and infections
and helps the Goldfish to move through
the water faster. Some fish species also release
toxins in their slime which ward off enemy attacks. Other fish
species use their slime to feed their young.

Gills enable the Goldfish to breathe. Gills consist of thin
sheets of tissue containing blood vessels. As water passes over
the gills oxygen is absorbed into the blood stream Carbon
dioxide passes out into the water. The gills are protected by a
large bony plate called an operculum. Some fish species however
have lungs and breathe air.
