Koi Diagnostics

Here at C N Koi, we not only cover Pond building and selling koi but we offer a after sales service for koi health as well. So any problems that you may encounter with your precious koi, Stewart is certified in diagnostics and diseases. So this means that Stewart can come out to you and do some skin biopsy’s and find out what your problems are. Most situations are from parasite problem’s normally. We are also backed up with veterinary surgeon’s so that we can do a postmortem,  and get samples sent of to a laboratory for testing to find out what your koi has died from. In most cases thought fish suffer from parasite issue’s. But there are occasions where there are viral or bacterial issues.

How to Know if My Koi Fish is Sick?

Changes in behaviour, such as erratic swimming, koi swimming upside down, abnormal feeding patterns or isolating themselves from others can indicate that your koi fish is sick.

Physical symptoms like necrosis of the gills, cloudy or popped eyes, raised scales and swollen abdomen are are signs that your fish are unwell and a skin biopsy will tell us which parasite you have.

The simplest way to catch signs of disease or stress early is to become familiar with your koi’s behaviours. Sick koi will exhibit common patterns and are easy to spot!

If you have observed any unusual behavior patterns, you will need to physically examine the suspected koi.

You can diagnose a lot with the naked eye but here at CN-Koi we can investigate deeper.
