Fenbendazole Flake delivers the dewormer through food — useful for fish still eating but suspected of internal nematodes, or for ongoing display-tank hydroid management without dosing the water column. The gentler delivery for fish too stressed for chemical baths.
Active ingredient: fenbendazole, impregnated in flake form. Fed as sole food source during treatment. Pairs cleanly with praziquantel for combined flukes + worms coverage. Safe for hard corals when fish-fed; remove sensitive softies (Anthelia, Xenia) if any leaks through. For exact feed schedule, see the Dewormers tab on our Medication Dosing Calculator.
Treats: intestinal nematodes (roundworms), some flatworms, hydroid prevention (when fed regularly).
Use in: quarantine, hospital tank, or display.
Reef safe: yes for stony corals; remove sensitive softies first.
