Hi,
My Flowerhorn seems to have slime / fungus on its body. I've tried using Machalite green and Melafix, together with a water change (50%), and it cures completely (or at least my eyes cannot catch anything...) However it will return a few days later. This has been on going for several months and I just can't seem to get a solution to this... Kindly advise why is this so? I will try to post a picture when i get my hands on a camera.

Thanks,
Morhpeous
