Help protect aquarium fish from internal parasitic worms with Fritz Expel-P, a targeted deworming treatment designed for freshwater and saltwater aquariums. Formulated with levamisole hydrochloride, this anti-parasitic medication is especially effective against nematodes and other susceptible roundworms that can affect fish health, appetite, and body condition.
Fritz Expel-P is designed to treat parasites such as roundworms, nodular worms, and hookworms. These infections may cause visible worms protruding from a fish's anus, weight loss, abdominal bloating, reduced appetite, or unusual breathing. By targeting susceptible parasitic worms, Expel-P helps aquarium owners manage internal parasite problems with a convenient packet-based treatment.
In addition to aquarium fish treatment, Fritz Expel-P can also be used as a coral dip to help remove certain flatworms and pest nudibranchs. Its versatile formula makes it a useful option for both freshwater and marine aquarium care when applied according to the manufacturer's directions.
Internal parasites can interfere with digestion, nutrient absorption, and overall fish condition. Fritz Expel-P contains levamisole hydrochloride, an anthelmintic ingredient used to treat susceptible parasitic worms.
The product is formulated to target:
Nematodes: Parasitic roundworms that can live within fish and affect their health.
Roundworms: Internal worms that may contribute to wasting, poor appetite, and reduced body condition.
Nodular worms: Parasites associated with nodules or abnormal tissue growth.
Hookworms: Susceptible parasitic worms that can affect fish health.
Possible signs of infection include a thinning body despite eating, abdominal swelling, reduced interest in food, rapid breathing, or worms visibly extending from the vent. These symptoms can have multiple causes, so accurate identification is important when selecting a treatment.
Important: Fritz Expel-P does not treat tapeworms or flukes. For those parasites, consider an appropriate alternative such as Fritz ParaCleanse or another product specifically labeled for the identified organism.
Fritz Expel-P contains levamisole hydrochloride, an active ingredient used to control susceptible internal parasitic worms. Each packet contains 113 mg of levamisole hydrochloride, providing a convenient way to measure treatment doses.
The formula is designed for use in freshwater and saltwater aquariums and can help manage worm infections without harming the biological filter when used as directed. The manufacturer also identifies an immunostimulant benefit, making Expel-P a useful addition to an aquarium fish-health routine.
Expel-P is intended for specific parasitic worms rather than every type of fish parasite. It should not be confused with treatments designed for flukes, tapeworms, protozoan parasites, or bacterial infections.
Fritz Expel-P is formulated for use in both freshwater and saltwater aquariums. It can be used to treat compatible ornamental fish affected by susceptible internal worms.
For best results, Fritz recommends treating fish in a separate quarantine or hospital aquarium when practical. This makes it easier to monitor affected fish, observe expelled parasites, and manage treatment.
The manufacturer states that Expel-P is safe for plants, invertebrates, and the biological filter when used as directed. Some snail species may be temporarily affected but are expected to recover.
Fritz Expel-P uses a simple dosing schedule with a follow-up treatment to help address reinfection from parasites that remain after the initial dose.
Initial treatment: Add one packet per 10 US gallons of aquarium water.
After 24 hours: Perform a 25% water change and carefully remove expelled worms and parasites from the aquarium.
One week later: Repeat the treatment to help prevent reinfection.
Additional treatments: Repeat weekly as necessary, following the product label.
For aquariums smaller than 10 gallons, accurate dosing is important. Fritz provides instructions for preparing a diluted solution so that smaller amounts can be measured more reliably. Refer to the manufacturer's small-tank dosing guide before treating smaller systems.
Remove activated carbon and other chemical filtration media during treatment.
Turn off UV sterilizers while treating.
In marine aquariums, discontinue protein skimmers during treatment.
Keep aquarium lights off during the first 24 hours because the active ingredient is light-sensitive.
Maintain adequate water movement and aeration.
Avoid unnecessary water changes during the initial treatment period, except for the recommended 25% change after 24 hours.
Monitor fish closely and observe for expelled worms or signs of distress.
If ammonia or nitrite becomes a concern, use an appropriate aquarium water conditioner according to its label.
Always follow the current package instructions and seek advice from a qualified fish-health professional if symptoms persist.
In addition to treating aquarium fish, Fritz Expel-P can be used as a dip for certain coral pests, including flatworms and pest nudibranchs.
Dip concentration: Use three packets per two US gallons of saltwater.
Treatment time: Place affected corals in the dip for up to 30 minutes.
Water movement: Maintain adequate flow during the dip to help dislodge worms.
After treatment: Return the coral to the display or quarantine aquarium once worms stop falling off, following the manufacturer's instructions.
Expel-P does not affect parasite eggs. Manually remove eggs when possible or repeat the dip after hatching. The manufacturer permits repeating coral dips once per week, up to three times.
Use a separate container for the dip, and never pour used dip water directly into the display aquarium.
Choose the package size that best fits your aquarium treatment needs:
10-count package: Treats up to 100 gallons.
20-count package: Treats up to 200 gallons.
Each packet contains 113 mg of levamisole hydrochloride. Treatment capacity is based on the manufacturer's recommended dose of one packet per 10 US gallons.
