I posted a few days ago about my orange fish that has turned white. He was solid orange, and now he is about 80% white. The change happened in only 5 weeks. He appears normal, eating and swimming like crazy. Today I noticed that his gills seem to be pretty red and the area around his eyes are bright orange. What could this indicate? Does it mean he's sick or do gills just look more red against a white fish? No other fish seem to be affected by anything and the one who is affected is the smallest one, if that matters.
