Hello forum! I noticed my stepson's coral beauty angelfish is not as active as we got it. I observed that the gills is kind of orange and reddish in color same as with the base of its fins, around the mouth. There are also white spots. The reddish color is new to us. I looked at some books to try to identify the problem but I got no concrete answer. I don't know what is this disease, please help us to identify and advice us with the proper treatment. Thank you!
