Definition: Anchor worms (Lernaea sp.) usually generally only affect pond or outdoor fish such as Goldfish, however some Cichlids may also be affected. Lernaea burrow into the muscle and gill tissue of fish, and can reach as deeply as the internal organs. Heavy infestations can cause significant weight loss and even death.
Infected fish can be seen with whitish red worm-like threads, about one quarter inch long. The parasites can be found anywhere on the body of the fish, including the eyes, gills and fins. Raised ulcers may appear at the site of attachment, and secondary bacterial infections may occur.
