well my festae has internal parrisite and i have treated her with jungle parrisite clear 3 times allowing 48 hrs inbetween treatments. i have always had good results with jungle products but this time after 3 she still has white clear stringy poo. water changes are plenty and will not eat the parrisite food they make so i dont know what else to do besides dumping in more treatments. i figure if 3 didnt do it then anymore probably will not either.
