Koi fish are beautiful and colorful. They are also a joy to keep. But like all pets, they can get sick. It’s important to know about common diseases and how to prevent them.
Common Diseases in Koi Fish
Let’s look at some common diseases that can affect Koi fish. Knowing these can help you keep your fish healthy.
1. Ich (white Spot Disease)
Ich is a common disease in Koi fish. It is caused by a parasite. The fish get white spots on their bodies and fins. They may also scratch against objects.
2. Fin Rot
Fin rot is another common disease. It causes the fins to look torn and ragged. Bacteria usually cause fin rot.
3. Ulcers
Ulcers are sores on the fish’s body. They can be red and inflamed. Bacteria or parasites cause ulcers.
4. Dropsy
Dropsy is a serious disease. The fish’s body swells up. This happens because of fluid buildup. Bacteria often cause dropsy.
5. Gill Flukes
Gill flukes are tiny parasites. They attach to the fish’s gills. This makes it hard for the fish to breathe. The fish may also gasp at the surface.
6. Anchor Worms
Anchor worms are long parasites. They attach to the fish’s body. The fish may try to scratch them off. This can cause wounds.
