Introduced into aquariums by infected fish, juvenile anchor worms are small crustaceans that penetrate the fish's scales and enter the muscles. In the muscle tissue they lay eggs and then die. This causes Damage and infection.
Prevention is difficult. Even quarantining the fish will not prevent Anchor Worms because they mature very slowly and go undetected for weeks.
- Scratching against objects in the aquarium
- White/green threads protruding from the scales
- Inflammation around where the worm attaches
- Physical removal of the parasite
- A saltwater bath for freshwater fish for about 5-10 minutes per day until the worms die
