I have two male fighting fish in a tank with a clear divider, one side has two rocks and one side has one. I feed them 2 balls of food in the morning and 1 at night. I clean the tank every saturday, full empty rinse everything re-equalise the water to balance the chlorine. One of my fish, blue appears to have lost a circle of scales between his eyes, I have only had him about a month and he has no parsites as faar as I know.
I'm at a loss plz help me!
