I agree with Jann in not treating with the Metronidazole unless you know what you have. The Panacur really shouldn't hurt anything, but again I am not one to treat things unless I know what I am treating. Feeding your feeders Herptivite really won't do anything for your cham. If I were you, get a good fresh fecal in ASAP and see what you are dealing with. You could use the Panacur just to be on the safe side if you like.
