Fish Tapes is a safe and effective worming agent designed for the removal and prevention of flatworms and parasites in aquatic environments and within fish themselves. It works to combat the infection on both fronts to help promote quicker results.

Directions for Use:

Add 1 level teaspoon (approximately 3.1 g) into aquarium for every 4 gallons of water. Begin treatment with new water and do not stop filtration. Remove activated carbon and UV sterilization to ensure effectiveness. Distribute the contents around the edges of the environment or directly into the filter box for the best overall distribution. Do not apply more than once every 3 to 5 days. One treatment of 5 to 7 days is generally sufficient. Fish Tapes may be used as a preventative when used only at the standard treatment. Do not use with any other drugs. Use in saltwater systems where flatworms of the Polycladida order are being cultivated is not recommended as some contradictions will apply.


For aquarium and ornamental fish only. Not for human use. This product should not be given to fish intended for human consumption. Keep out of the reach of children and animals. In case of accidental overdose, contact a health professional immediately.


Keep container tightly closed and in a cool, dry place.
