Fish ich (pronounced “Ick”) is one of the most common and persistent diseases in pond fish. The ich parasite encysts in tiny white spots on the body, fins, and gills of fish. Along with the visible white spots, fish are often seen flashing and gasping for air at the water’s surface. Prompt ich treatment is essential for the survival of infected fish.
What Causes Ich Fish Disease?
Ich, short for ichthyophthirius multifiliis, is an opportunistic parasite that infects freshwater fish. Fish are susceptible to ich infections when they are under excessive stress caused by pH fluctuations, rapid temperature changes, overcrowding, overfeeding, poor water quality, and insufficient oxygenation.
Can Fish Survive Ich Without Treatment?
No. If not treated, ich has a 100% fatality rate, and death can occur within a week of infection. Ich is highly contagious and quickly spreads to other fish in the pond. We are here to help.

Ich Treatment for Fish
Ich medicine for fish quickly and easily wipes out ich and other common parasitic and fungal infections. The best ich treatment combines the following medicines with routine maintenance like water changes and salt baths:

Partial Water Change Cycle
In addition to adding ich medicine, a successful treatment includes a partial water change (25-30%) because such infections are commonly seen in poor water conditions. Check out this guide to learn how to drain a pond for water changes.

Pond Salt Bath
Pond salt is a form of pure evaporated sea salt that is commonly added to koi ponds to support fish health.

How to Prevent Ich in Fish
You can prevent many common fish diseases with routine maintenance like water testing, partial water changes, proper filtration, aeration, and fish population control. Learn more about preventing sick fish here.
First, ensure you do not have more than two koi or three goldfish per 200 gallons of water. This will prevent overcrowding, making disease prevention easier.
Finally, remember that oxygen is the lifeline to your pond’s ecosystem. Adding or increasing bottom-diffused aeration systems is the most effective way to circulate water and increase oxygenation.
