picture two beautiful fish swimming side
0:05
by side in a pond one is large and
0:08
elegant with flowing fins and vibrant
0:11
patterns the other is smaller rounder
0:13
and golden these are KO goldfish often
0:16
mistaken for being the same species but
0:19
are they really a common myth persists
0:22
that koi fish and goldfish are simply
0:25
different varieties of the same species
0:28
however this couldn't be further from
0:29
the truth these two popular ornamental
0:32
fish are distinct species with separate
0:35
evolutionary histories koi
0:37
scientifically known as cyprinus ruof
0:39
fuscus are descendants of the common
0:42
carp they originated in Central Europe
0:45
and Asia goldfish on the other hand
0:48
belonged to the species carassius aratus
0:50
and were first bred in China over a
0:52
thousand years ago while both have
0:54
undergone extensive selective breeding
0:56
their wild ancestors were different
0:58
species entire the physical differences
1:01
between KO and goldfish are quite
1:03
significant koi are generally much
1:06
larger often growing to lengths of 2 to
1:09
3 ft while goldfish typically max out at
1:13
about 12 in Ko have a more elongated
1:15
torpedo shaped body whereas goldfish are
1:18
usually rounder and more compact the
1:21
most striking difference is in their
1:22
barbles those whisker like sensory
1:25
organs near the mouth have two pairs of
1:27
barbles while goldfish have none done
1:30
coloration and patterns also set these
1:32
fish apart koi are renowned for their
1:35
diverse and intricate color combinations
1:38
including white black red yellow blue
1:42
and cream they often feature bold
1:44
patterns like spots or patches goldfish
1:48
while available in various colors are
1:50
most commonly seen in shades of orange
1:53
red or yellow with less complex patterns
1:56
the fins of these fish differ as well K
1:58
we have larger more pronounced fins
2:01
especially their Dorsal fins goldfish
2:04
particularly fancy varieties can have
2:06
more elaborate flowing fins but they're
2:09
generally smaller in proportion to their
2:11
body size compared to koi when it comes
2:13
to Habitat both species can thrive in
2:16
ponds but their preferences differ koi
2:18
are cold water fish and can tolerate a
2:21
wider range of temperatures they prefer
2:23
deeper waters and require more space due
2:26
to their larger size cfish are more
2:29
adaptable to smaller environments and
2:31
can even live in well-maintained
2:33
aquariums which is not suitable for koi
2:35
behavior and lifespan also distinguish
2:37
these species koi are known for their
2:40
longevity with some individuals living
2:42
up to 50 years or more in optimal
2:45
conditions they're also more interactive
2:46
with humans and can be trained to eat
2:48
from hand goldfish while still
2:51
potentially long lived typically have
2:53
shorter lifespans of 10 to 15 years
2:56
they're generally more skittish and less
2:58
likely to interact directly with humans
3:00
culturally koi hold a special place in
3:03
Japanese tradition they symbolize
3:05
perseverance strength and good fortune
3:08
koi breeding is considered an art form
3:10
in Japan with certain color patterns
3:13
highly prized goldfish while popular
3:16
worldwide don't carry the same level of
3:18
cultural significance in conclusion
3:21
while koi and goldfish may seem similar
3:24
at first glance they are distinct
3:26
species with unique characteristics from
3:28
their size and appearance to their
3:30
behavior and cultural importance these
3:33
fish have many differences that set them
3:35
apart so next time you see a beautiful
3:37
fish in a pond take a closer look you
