The Gosanke category consist of the Kohaku, Sanke and Showa types of Koi. The colors that make up the category are a combination of red, white and black. These are the most sought after Koi in Japan. They are prized for their beautiful colors. Almost all Koi shows are won with one of these Koi.

This is a scaleless metallic white koi with a metallic yellow pattern. These Koi are rarer and tend to be more expensive than their Kikusui counterparts. The yellow can either come in a Kohaku-like pattern with "steps" of color or a Shusui-like pattern with long wavy strips of color.

Spring Care of Koi

This time of the year is the toughest on Koi. The problems that plague them include:
  • Disease
  • Temperature Fluctuations
  • Predators
  • Stress

The Koi that spend the winter outside have just come out of hibernation. Their immune system really isn't up to snuff for dealing with the onslaught of problems that arrive with this season. Large temperature swings screw with their metabolism. Small ponds that don't receive any shade are susceptible to this. The life cycle of parasites is still slow, but they still will infest and overwhelm a Koi. The damage they do will take a long time to heal, so extra care must be taken to keep an eye on the Koi's behavior. Koi will swim slowly in the cold water and may pause for a while on the bottom, but they shouldn't list on their side when swimming or resting. Watch for flashing too.

Koi will also be weak from fasting and living off of their fat for an extended period of time. Any stress will take an extra toll on the fish's health. Predators will be the primary source of stress. Netting should be placed over the pond to prevent any predators from entering and harming the fish.

Koi Fish Feeding Swarm

These Koi are nuts, they eat their food like no tomorrow. I would not want to get caught in the middle of that feeding frenzy.

The Shiro Utsuri

The Shiro Utsuri had three pellets of Koi food. He wanted to bring them to his nook and save them for later, but he had only one mouth to move them with. He didn't want to leave the pellets, he was afraid some other fish would come along and gobble them up.

The Shiro Utsuri was pondering his dilemma when a small red and white Koi appeared. He asked the little Kohaku if he could help move the pellets. The little fish tried with all his might, but he wasn't strong enough to make the smallest pellet budge.

A little while later, a big yellow fish slowly made his way across the bottom of the pond. The Shiro Utsuri asked the old Yamabuki if he could help, but alas, he was to weary to help either.

"I can't move this food all by myself. I might as well eat it now and just save the single pellet that I can move."

Along came a little tadpole. He noticed that the Shiro Utsuri was sad.

"What's bothering you my friend?" asked the tadpole.

"I have three pellets of Koi food, but I can't move them all and once and I'm afraid to lose them while I am bringing them home one at a time."

"I know," the tadpole said, "make a bubble to put the pellets in and then you will be able to carry them all at once to your home."

"But who will guard the pellets while I am at the surface?"

"I will!" said the little tadpole, "I will make sure no one touches your pellets of Koi food."

"But what do you want in return? One of my pellets?" the Utsuri inquired.

"No, I just want a chance to prove myself. Everyone thinks that a little tadpole like myself isn't capable of great things. I want to prove them wrong."

"What happens if you aren't able to defend my pellets and someone eats them all? I won't have any then."

"I swear on my honor, these pellets shall go un-eaten or I will swim to the shores of the pond to find you 3 new pellets."

"Alright then, off I go!" The Shiro Utsuri swam to the surface and formed a bubble. He took a his time to swim back downs, he did not want to burst the bubble and take even more time than he had to.

How to get Ammonia out of fish pond? - Judy

There are three ways to remove Ammonia:
  • Water Changes
  • Altering Fish Care
  • Increasing Filtration
Water Changes can be used to remove Ammonia from the pond. Fresh waster from a well is the best source. City water will need to be chlorinated.

You can also lower the water temperature, reduce feeding or remove some fish from your pond.

The only permanent option is to add more filtration to the pond. A filter will take Ammonia and will transform it into less harmful chemicals.
