I have a pink square anthius, i've had them for quite sometime almost two years. I knew he was a male because obviously he had a very deep purple/pink color and of course a pink square. I've noticed within the last few months his pink is beginning to fade and turn orange...now, I know females are orange does this mean he is turning back into a female? My water quality is great and he eats a wide range of things , so it cant be diet. what do you guys think?
