What Are Anchor Worms?

Anchor worms are a type of parasitic crustacean that can affect freshwater fish in aquariums and ponds. They get their name from the way they attach themselves to the fish, using two anchors at the front of their body. While not normally fatal to fish, anchor worms can cause irritation and lead to other health problems if left untreated. 

Common Symptoms of Anchor Worms

• Red and inflamed scales
• A whitish-green thread-looking parasite protruding from the fish's skin
• Scratching or rubbing against objects in the tank or pond

How to Treat Anchor Worms

There are a few different ways to treat anchor worms, depending on the size of the fish. Regardless of size, you should always start with cleaning the tank or pond and ensuring the water quality is good.

For larger fish, you can typically remove the parasite by pulling on its body. Once removed, we recommend applying some topical antibiotic ointment to the affected area as this will help prevent any secondary infections.

For smaller fish, you will need to add a medicated concentrate to the water to treat the fish for anchor worms as removing them physically could further harm the fish.
