I have two angelfish that I have had for maybe 3 or 4 months. All of a sudden I notice that they have both turned blue. I did some research and found out about these blue Philippines. Can anyone help me identify if that is what these are? The light part on both fishes dorsal fins have a blue tint. Also the long fins in the front have turned blue. Is this normal? I have read that changes in the water can change their coloration. I recently put in a co2 device. Seems like it happened shortly after that. My fish all seem healthy and happy.
