now, looking at the pic of the male, I wonder if that is the fish I have. Everything looks the same cept the yellow. When he starts to change his color, it's almost all blue. He doesn't keep any yellow when he is chasing the female around.
Also, the first female that has been in the tank with him since I bought them, he nearly killed. I had to remove her and have her healing (hopefully). there is another female in the tank, bigger than the first. She seems to be okay, but, he is on her constantly.
