Gday Everyone, My sailfin is about 9-10 cm and supposedly has got Protozoan Parasite { Flagellates } One of his poops the other night was like white cotton, it was cotton a bit of poop, cotton a bit of poop.. he is still eating and active, and his stomach is not shrunken.. I was told to treat him with Metronidazole, you can get from a vet.. I live in a country town in Queensland, Australia and am having a hard time getting some, Im just wondering whether a normal Parasite eliminator medication will be enough to treat this.. Thankyou for any advice on this problem.. Cheers
