Vitamin Deficiencies

Vitamin & Mineral Deficiencies

What exactly happens?

I constantly hear people say that they save money by feeding their Koi something other than a quality koi food.  Normally I keep my mouth shut in response, but since this is my article, I can give my opinion.

Yes, your Koi will “live” on trout chow, catfish chow, or other types of food.  I even met a person who fed ground up cat food, not catfish food, CAT FOOD.   Likewise, you and I could live on Donuts, or bacon cheeseburgers, but we wouldn’t be in the best of health.

If you expect your koi to grow healthy, strong, & disease resistant, make sure you feed a healthy “Koi” food.  I’m not going to endorse one food over another here, because there are many quality foods out there and they keep getting better.  I just ask that you read the labels, compare brands, & buy food designed specially for koi.  It is even a good idea to use more than one so you are sure to get enough of the proper vitamins.

You have probably heard not to use food that has “corn” as one of the first 3 ingredients because Koi can’t digest it.  But did you know what the following deficiencies can do?

Vitamin A Impaired growth, body depigmentation, pop eye.
Vitamin D3 Poor growth, impaired calcium balance.
Vitamin E Anemia, increased water retention.
Vitamin C Scoliosis, deformative growth, hemorrhagic skin, liver, kidney, intestine, and muscle.
Riboflavin Cloudy eyes, hemorrhagic eyes, dark body coloration.
