I have 3 bettas in 3 different tanks. I have been treating all 3 with Bettazing and this is the second week of the treatment. I don't have any gravel or any covering on the bottom of their tanks, and have noticed that all 3 have these white "droppings" as well as what I consider normal fish (sorry to be graphic) excrement. I also saw some of that stuff on Blueboy and it seemed to be coming from his gills. They are all eating well and seem energetic, but this doesn't seem quite normal. Can anyone help?????
