ok so i have a GT pair, the male is a petsmart GT but the female is from a good lfs, now the male has white stringy poo pretty much all the time, though sometimes its not stringy, its like the regular consistency but white in color, the female usually has normal poo but i have seen her have stringy poo a couple of times, now i thought this might be parasites but they were in my 120g and didnt want to treat whole tank so i just medicated their food for a week (2x day) after this i saw him have a normal poo but now it white again, so now iv taken them and put them in my 20g long holding tank and am going to treat the water and everything for parasites but what else could it be? i mean if it were parasites shouldnt the week of treated food have killed them? they are luckily still eating so i really want to figure out what it is and cure it before they get to the point of no return, what else could cause white stringy poo but not a change in behavior?
