Guys.. My friend owns a juvenile flowerhorn (male) he is brightly colored(before) and active feeding.,but suddenly he falls sick with colors all faded and was not taking food for some days nearly he met his death but treated with metronidazole for his hex. But now he is very active feeding on feeders (I said no to feeders. He actually feeds on hikari too but same white poop) and the color is dull as you could see in this picture and still the thing is he is having hex . Can u guys help in this since he lost all his colors and the main thing is white pooping(very thin threads) but he is super active and taking his feed with eager.
