Fritz Expel-F is an antiparasitic treatment formulated specifically for freshwater and marine aquaria. Each box contains 20 premeasured doses designed to eliminate external fish parasites such as flukes, ich (protozoan parasites), and other ectoparasites. The product is intended for spot treatment of infected fish and for quarantine use.
Key Features
Quantity: 20 individual doses per box
Use: Treats external parasites (flukes, ich, other ectoparasites)
Aquarium type: Suitable for freshwater and marine systems
Dosing: Premeasured doses for accurate, convenient application
Application: Designed for bath or targeted treatment rather than continuous whole-tank dosing
Benefits
Convenience: Premeasured packets remove the guesswork and reduce the risk of overdosing
Effectiveness: Formulated to act on a broad range of external parasites commonly seen in aquarium fish
Safety: When used as directed, safe for most fish; minimizes stress with short-duration treatments compared to continuous medications
Quarantine-ready: Useful for treating new or sick fish in hospital/quarantine tanks before introduction to main displays

Use in a quarantine or hospital tank when possible to protect invertebrates, corals, and sensitive species in display tanks.
Prepare a treatment bath by dissolving one dose in the specified volume of water as directed on the packet.
Move the affected fish into the treatment bath and monitor closely for signs of improvement or distress.
Follow recommended exposure time and number of treatments; do not exceed maximum stated concentration or duration.
Perform water changes and water quality checks after treatment as recommended.
Safety and Compatibility
Not recommended for use in tanks containing invertebrates (shrimp, snails), corals, or sensitive species unless the label explicitly states compatibility.
Consult product instructions regarding use with filtration, activated carbon, and UV sterilizers; remove or bypass as directed to ensure efficacy.
Avoid concurrent use with other medications unless approved by the manufacturer or a veterinarian.
Store in a cool, dry place away from direct sunlight and out of reach of children and pets.
When to Use
Visible signs of ectoparasitic infection (white spots, flashing/scratching, rapid breathing, clamped fins)
New fish arriving from a store or another system (as a precautionary quarantine treatment)
After observing parasites on tankmates despite regular maintenance
