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 brief article by Syd Mitchell explains the part that plants play in the Nitrogen Cycle.

The Australian government has postponed the decision to release Koi Herpes Virus (KHV) for a year, so they can continue to study the timing and effects.

This article is about a recent surgery done at UC Davis - School of Veterinary Medicine.  The Koi survived the surgery and was doing well 10 weeks later.  It should be noted that the vast majority of tumors reappear within a year, and will cause mortality, such that the surgery was more about learning than about the long-term survival of the Koi.

Thanks to Monte McQuade, our own Show Water Quality instructor, for sharing his heartbreaking experience.

A Tiny Fish Just Passed a Classic Self-Awareness Test With a Mirror!  Even cats and dogs can't do it.

While this article by Taro Kodama is a bit commercial in terms of recommending their own products, it does have very good info, and is worth the read!  I did not include, but they do sell, a complete Q tank kit and a complete accessory kit – the both contain a good group of items.

Goldfish in Paris are getting a second chance to just keep swimming, even after their owners kick them out of their tiny fish bowl homes.

These are some useful tips from Kodama Koi.  Their FL facility was hit by a hurricane last year, and this year, their Hawaii facility was hit, so they have some good advice!

Our Koi can survive lots of different water parameters, but these fish are even more amazing!  You will enjoy reading the story about their rare habitat.

The swim-bladder, also known as an air bladder, is an air-filled sac situated just under the backbone at the top of the abdominal cavity.

Stress has such a huge impact on Koi that it warrants an article on its own. Good Koi husbandry will not be possible without a decent understanding of stress and the effects on koi in a pond. To fully understand stress it is necessary to backtrack a little bit and consider the immune or defence systems of fish.  

Here is a very simple solution to a dry pond caused by a plumbing break.

If you are drawing water direct from your bottom drains.

Advice by Chris Neaves.

Chlorine is a toxic element, and excess chlorine could be harmful to fish and crustaceans, so it is important to remove chlorine from the water before introducing the stock.

What kind of salt?

The best salt to use in the pond is normal coarse salt.

Methylene Blue comes as a very dark green powder, appearing blue when dissolved in water. Considered a 'traditional' medication for bacterial, fungal and parasitic infections, it is used less frequently as it is highly toxic to plants and will wipe out the bacteria in a biofilter.

Many Koi keepers look forward to spending some time either relaxing at home or going away for a well-deserved rest. Being a Koi keeper does not mean that you cannot go on holiday! If that was the case, many people will opt not to keep Koi.

The purpose of this article is to assist the Koi keeper during those stressful situations when a “dead” Koi is discovered in or outside a pond. Take heart, it may not be dead but indecision or a lack of knowledge may be the reason that it will soon be really dead.
