So I have a Camallanus worm infection in my fish and am going to get it treated with Levamisole for my tank. If I have a 35 gal tank, what dosage do I need to soak with their food, and can I use flakes or is blood worms the preferred food method. Also I have a blue crayfish in my tank, will he get treatment from eating left over food or will he get it from what dissolves in the water?
