Hello Koi Enthusiasts!

This blog is here to provide a spot for various things that do or might pertain to Koi. This stuff is intended for your entertainment, and is not meant to meet the stricter standards of our ebooks and courses, so use this info carefully and at your own risk. The short articles here may be descriptions of techniques that have proved effective, an introduction to new fish research, facts, graphs or just something FUN about fish! This information can be a springboard for your imagination and an entertaining place to learn something new. Information that was first published in Question of the Week can be found here.

The more we learn about Koi, the more FUN this hobby is - and we always say - if you're not havin' FUN, you're not doin' it right!

CKKs (and other knowledgable hobbyists) are always telling others that they have to be careful about the use of antibiotics in our Koi.  The problem is that if you use an antibiotic and it is the wrong one (you can find out the correct anitbiotic to use by doing a swab of the infection site and sending it to a lab to be cultured), or if you don't use all the recommended doses, then you don't kill all the bacteria. The remaining bacteria are the ones that were hardest to kill, and they multiply.  Now what started as a simple bacterial infection has become a problem, and when the local dog or bird or frog (or fill-in-the-blank with any critter that visits your pond) passes the resistent bacteria along, we end up with bugs so bad that they can't be killed with any known antibiotic, and that kills people.

This article was first posted in Wired magazine by Maryn McKenna on April 15, 2011.  It is not about Koi, but about resistance in food animals.  SCARY stuff, and I think it illustrates the point!

Someone asked me this question, and I researched the following answer.

Ultraviolet lamps are comprised of two electrode filaments (the spring looking wire at each end), a glass and quartz combination vacuum tube, several inert gases and approximately 3 mg of mercury (Hg).

While thumbing through a magazine, I saw this ad...

OK - you just don't see this every day - Koi in the bath?  Not exactly sure what that says about this hotel...

One of my mentors in the Koi hobby was a guy called Roark, who used to have the most fabulous web site!  This article was originally posted on  This is still considered the bible on Potassium Permanganate use.  PLEASE READ COMPLETELY BEFORE  EVER USING PP!

Heart research funded by EPSRC at Durham University is using sophisticated optical technology to overcome the challenges of imaging living hearts which are located deep inside the body and move at 300 beats per minute.

OK - for those of us whose Koi are under the ice for the duration of winter, and have too much time...

This origami Koi is quite realistic-looking. The open mouth looks like when they are feeding - or just wanting to be fed! 

OK - not exactly about Koi - but you've heard of robotic fish?  How about the next gen of underwater robots?

A proposed ordinance which would ban the retail sale of dogs, cats and rabbits in Branford, CT was referred to an ad-hoc subcommittee by the town's Rules & Ordinance Committee at a hearing on July 2nd, 2013.

Let me start by noting that I live in Connecticut, and am usually proud of my state!  The state of Connecticut has compiled a long record of firsts.

Carp are smarter than you think!

What’s MOST important to Koi during a power outage?  Quick answer – AIR!  Koi require oxygen to live, and without an air pump or a water fall running, they will quickly consume all available oxygen in the pond and die! 

Chinese or Lunar New Year 2014 (The Year of the Horse) is officially on January 31st.

Rather than the traditional zodiak, the Inland Koi Society ( ) offers a Koi version!  What Koi variety were you born under?
