a week and a half ago one of my discus stop eating her waste was stringy white. So i went to a aquarium stop and bought some tapeworm med. added into the tank after half an hour she got her color back rosi red, i follow the intruction and repeat the treatment after a week. But she still hasnt started eating yet. and i saw her poop the other day it was yellow. What else is wrong with her? >_<

What food do you use? What dewormer did you use? Try adding garlic on the food to encourage her to eat.

i feed them color bits soak in garlic guard, live brine shrimp, frozen bloodworm spectrum food, frozen beef heart. she refuse to eat any of it. I used Aquamaster Flukes and tapeworm tablet. itz a 100gallon/ 380liter tank. Intruction say 1 tablet every 20liter so i use 17 tablet. cuz minus the gravel etc.
