Levamisole Flake is the targeted internal-parasite food — especially for stubborn internal nematodes that praziquantel and fenbendazole cannot reach. Delivered through food rather than as a 24-hour bath, which is gentler on stressed fish and works well in display tanks where you cannot drain and dose.
Active ingredient: levamisole hydrochloride, impregnated in flake form. Fed as sole food source during treatment. Stays in the gut; safe for biological filtration. Pairs with metronidazole for full internal-parasite coverage. For exact feed schedule, see the Dewormers tab on our Medication Dosing Calculator.
Treats: marine internal nematodes, some external parasitic worms.
Use in: quarantine, hospital tank, or display.
Reef safe: yes at therapeutic dose — active stays in the fish.
