What are Anchor Worms?

Anchor worms are a crustacean copepod parasite that embeds itself in the fish’s skin and has a worm-like tail that protrudes from the skin. There are several non-parasitic stages of these parasites that occur in the water.

Anchor worms are introduced into your aquarium with other fish and plants. Because they are very contagious, if a fish afflicted with them introduces a few into your tank, they will soon reproduce, proliferate, and infect everything else, including your betta fish.

Anchor worms are much easier to see on fish than on plants. Adult anchor worms are most likely to be transmitted by fish, but larvae are more likely to be transmitted via plants. The larvae are likewise much more challenging to see.
