Few topics spark more debate among aquarists than how to administer deworming treatments. Some insist that adding medication to the water is the only reliable approach. Others argue that medicated food delivers a cleaner, more targeted cure. Both camps can point to real-world successes, yet the truth is more nuanced than either side likes to admit.

At Pufferfish Enthusiasts Worldwide, every guide is a living document shaped by science and experience. Our understanding of aquarium life never stops evolving, and neither do our articles. Each update, discussion, and observation from our global community helps refine these resources and keep them accurate, practical, and alive.

This is the guide that turns uncertainty into understanding. Combining real research with practical fishkeeping experience, it explains what Camallanus worms are, how they behave, and how to stop them. While created for pufferfish keepers, this treatment protocol applies to many other freshwater fish species.
