"On another note, one of my yellow coris wrasses is changing colors...red tail and red and green around the head. Isn't this the colors of the male??? I tried to get a picture, but it's hard to tell, the colors are still muted."
Sure thing Mike, that will be your Alpha Male. My female stayed yellow and just got larger. I know I have other males and they at this time are about a quarter of the size of the Alpha male. It will be very interesting to see how much they change as they age. Mine spend all day picking at the rocks - everywhere, they are great!
