Over the past few weeks, my dwarf gourami has faded in color and became a little lethargic. I have been trying to figure out what was wrong with him for weeks, originally thinking he had Ick due to the prominent white spot on his fin, but nothing changed. Recently, I have used a general parasite powder medication and it seems to have helped somewhat. He acts, swims, and eats normally but still has slightly faded colors (but not nearly as bad as it was before treatment). Is he still sick or is this normal (I think he might have dgd)??
