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!

This is an excellent webinar about KHV and some things you can do to protect against it.  For those of you following the controvercy about releasing KHV in Australia to control invasive carp, this is a webinar from AVMA about it - and it has some good biosecurity suggestions for those of us who don't want KHV in our Koi collection...

These are fun!  See the link below for step-by-step instructions, and even a How To video!

Many Koi meds claim they can solve a multitude of problems, but their ingredients are secret!

Fungus on eggs has long been the bane of Koi breeders, whether they be professionals in Japan, or home hobbyist breeders here in the USA.  Reat the article about current research on ways to prevent fungus.

What is the correct way to use antibiotics to treat fish diseases?  Read this article by Dr. Loh, The Fish Vet in Australia, and also learn what K.O.I. courses you can take to learn more.

My Koi have adopted the whole begging thing - you know - body half outta water, mouth open - all we need is a sign - pour food here!  Dunno who's picture this is - but the spoon thing is brilliant - no waste!  Wish I'd thought of that!

Some guppies have a better sense of maths than others. It allows some to find the biggest shoal possible in which to be protected against predators, while others are better at choosing fruitful foraging ground. This is according to research conducted by Tyrone Lucon-Xiccato and Marco Dadda of the University of Padova in Italy in Springer's journal Behavioral Ecology and Sociobiology.  Read more by clicking on the title or picture.
