It appears that two of the KOI Show videos from last weekend
weren't uploaded correctly and would not play. Thanks to Terri
in Denudin FL for letting us know!
Here are the two video links again, for the two videos that would

Thank you for the wonderful pictures and video you have sent to
us,it's been a real wide eye opener I never imagined that there
was so many variety of Koy fish to me a koy fish was a fish and
that was it (hope you understand what I mean) but after seen the
photo it's becoming a pleasant and more interesting hobby .
I have 2 question for you and I'm sure you have the answer.
(1) It's true that the fish grows according to the size of the
pond or tank?
(2) How long does it takes for a Koy fish to grow to full size
and how fast do they grow
Glad you enjoyed the pictures and videos. Yes, there are many
varieties of KOI and what's amazing is that each style has been
created from thousands of years of selective breeding in Japan,
and all over the world.
To answer your questions:
Yes, it's *mostly* true that a fish will only grow as large as
his surrounding pond or tank. I say *mostly* because I saw
something at that koi show that I didn't not believe.
There was a fellow member of the koi club there, with 5 or 6 of
his VERY LARGE koi on display. I'm talking over 30" long for
some of them. What was amazing to me (and somewhat unbelievable)
was that his pond was only around 450 gallons.
Unbelievable, but true...
Let me explain.
The reason his fish were able to grow this large in a pond so
small is because he had his pond setup with a 'Flow Through
System' - What this means is that his pond is hooked up to a
well, and has a constant supply of new, fresh water flowing into
the pond - and the old water is constantly overflowing back into
So essentially - his fish live in the ocean! His pond water is
always renewing itself, with a constant supply of minerals
without any buildup of fish waste or toxins.
However - for most of us, the rule does apply. Fish will only
grow as large as their environment will support. I've heard, but
am not certain of, that fish produce a certain waste chemical
that actually can regulate their growth. If the level of this
chemical is above a certain level, the fish's metabolism will
adjust and stop growing.
However, as in the case of the flow through system - if the by
product chemical is not present, then the fish will continue
To answer your second questions, KOI and most fish will reach
their full size within 3-4 years, although can continue growing
well after that. It depends on a lot of factors (diet,
surroundings, water quality, etc)..
