I had posted a rant about a particular seller and their terrible shipping and service but, after praying on it, I have deleted all references to them. This page had been designed to appear near the top of every search engine. I don't want to harm their business. They can do that to themselves.

Instead, I recommend Fritz Expel-P. Also, with a little research and care, you can purchase Levamisole for non-aquatic applications and use it in your aquarium.

RECOMMENDED:

Fritz Expel-P

Levamisole (specifically Levamisole Hydrochloride) is a potent dewormer widely used in the aquarium hobby to treat internal parasitic infections in freshwater fish. It is particularly effective against nematodes (roundworms) such as Camallanus and Capillaria, which cause "wasting disease" or "livebearer disease" characterized by severe thinning despite normal eating habits.
