Koi Health

All fish carry parasitites , this is normal and in itself doesn't present a problem, the problem arises from situations such as poor water quality, poor handling, overstocking and fluctuating temperatures - in fact anthing that causes the fish to become stressed - parasites are opportunists and will take hold during these vulnerable times.

A change in your fishes normal behaviour is usually the first indication that they may be suffering from stress or ill health.  Time is never wasted by observing your fish, in fact regular observation is essential - being aware of their normal behaviour  will help you detect a problem as it arises.

Before adding any chemical  treatment to your pond you must always read and follow the manufacturers guidelines, have a plentiful supply of air, know the exact gallonage of your pond, know the temperature your pond is sitting at as most treatments are temperature dependant and what exactly it is you are treating via a microscopic diagnosis (overdosing or using the wrong treatment could have castrasophic results).

If your fish display any of the following characteristics you must firstly carry out a water test, if the results are fine then a mucus scrape should be taken - use this opportunity to look over the fish including it's underside for any obvious damage or signs of injury.

CHARACTERISTICS TO LOOK OUT FOR:

Flashing/Flicking (rubbing themselves along the bottom or against the pond walls)

Staying stationary with clamped fins/decreased activity

Sulking at the bottom of the pond

Gasping for air

Laboured or rapid respiration  

Lethargic

Heavy mucus

Not feeding

Remember: microscopic examination is the only way to get an accurate identification of the particular parasite.

In addition to parasites fish can be at risk from other ailments such as diseases and bacterial infections - these are also explored in this section (coming soon).

Please note:  Where treatments have been recommended they are based on the following; expert opinion, research and what we've experienced as being the most effective.  They are by no means the only effective treatments available.
