I've since done a little more searching and reading, and internal parasites are definitely a possibility. Would explain the fish getting thinner, glacing off objects, and the odd stringy poops they have had off and on.
I'm wondering if praziquantel would be as effective as panacur? Hikari makes a product for aquariums called PraziPro that is supposed to be effective treatment for flukes, tapeworms, flatworms, turbellarians, and can be used as a preventive. Plus it doesn't affect the biofilter. Has anyone got experience with this product? Could I use that and alternate with a dose of metro soaked food to treat internal parasites?
