About Koi-Care

As an aquatic biologist I have a natural interest in fish and have since I was 8 or 9 years old. From my humble beginnings with a ten gallon tank hosting goldfish to caring for large koi ponds, I have learned much. I try to share as much of what I have learned over the years on my site and hope to improve and expand the information in the coming years.
