As pond owners and koi hobbyests, we all hate to see this in the news!
 
 ST. GEORGE, Utah — Dumping unwanted goldfish or other aquatic pets into reservoirs might seem like a humane way to dispose of them, but these invasive species can wreak havoc on fisheries, the St. George News reports.

Humans have been the only known species to domesticate other animals - until now.

In our new study, we describe what appears to be first example of a non-human vertebrate domesticating another animal...

A research paper on the reflective properties of koi scale and skin. A must read for our research minded members!
 

A great article on the basics of koi reproduction in your pond.
 
...It takes approximately a year for eggs to fully develop within the female koi. Eggs formed in the spring of the first year will be dropped in the spring of the following year. The eggs produced by the female are not fertile. The male of the species releases sperm onto the eggs after the female has dropped them. After the spawning has taken place, new eggs will begin to form. These eggs will be released during the next year's spawning.
 

So how did we really get the most common ornamental fish in the world?  Scientists are working to figure it out. This article is for all you research lovers!
 

Amazing research about damselfish domesticating shrimp!
 
...Now, researchers have discovered fish that seem to be using shrimp in the same way we would use a farm animal.
The team thinks it could be the first example of a vertebrate species – other than human – domesticating another animal.

This is the lightweight version of this research. If you want to read the scientific paper use link below. 
 
A large team of researchers affiliated with multiple institutions in China has sequenced the genomes of a large number of goldfish and carp, revealing much of their shared origin. They've published their results in the Proceedings of the National Academy of Sciences.

Okay, which of your koi have the behaviors associated with effective leadership?
 
Good leaders needing to strike a balance between striving to reach goals and keeping their followers with them has deep evolutionary roots, according to a new study from the Universities of Bristol, Harvard and Princeton on schooling fish.

Fish and humans are similiar when in risky situations
 
New research carried out by scientists at the University of Bristol has shown that despite individual animals having their own personality, this gets suppressed when they make decisions together in a group.
Dr Christos Ioannou and his colleagues from the School of Biological Sciences tested three spined sticklebacks (the UK's smallest ) alone and in groups of ten.

This story will have me observing my koi's swimming patterns much more as I carefully for personaliy.
The way a fish swims reveals a lot about its personality, say scientists
