One of my adult Red Empress females has a slight white sheen to her body (not on her head or tail) her top and bottom fin are pale and looking a bit ragged. (It doesn't appear to be nips from the other fish...I've seen plenty of that in other tanks over the years.) She is swimming and eating just fine. She is in a 75gal. tank with another female Red Empress, an adult Male Red Empress and a juvie. Lost track of time, not sure exactly how long I've had her...but sure she's over 2 1/2 to 3 years old. Your help is greatly appreciated! Hate to lose her!!
