Just wondering what the best way to treat a parasite infestation? I have a tank full of fish who are infected and need to treat the whole group. I'm not sure exactly WHICH parasite it is, I suspect perhaps flukes but I'm not sure, so for sake of argument lets just go with what treats internal and external parasites. I purchased some Prazipro and dosed the tank on Saturday...waited three days, did not see any improvement, and did a second dose per the bottle instructions. Second dose was on Tuesday. I still have not seen any improvements at all. Should I stick with the Prazipro, give it more time and/or more doses, or try something else? I'm very limited as to what I can get here, small town with very limited selection, but I THINK I can get my hands on some API General Cure for parasites. Should I give that a go? Which have you found to be more effective? It's at the point where I'm seriously starting to consider that my entire tank might be wiped out...
