You're right about them being slow growers. At least they have been for me. I cropped your photo and included it here. Notice that the amount of blue near the back of the gill plate is quite extensive, just like females that I have. Compare the two pictures, yours first, then mine.ocassionally you can see the white lines on either side of the spot but usually when it gets spooked and its colors wash out. when it was younger the lines were more noticable but they seem to be fadeing away as it matures. and i can keep you posted on pics but they seem to be slow growers and havent grown much in the 5 months ive had em
