I am looking to buy a gold flake angel from a fellow hobbyist by me and I always thought their tails would be dark black from all the pictures I see. The I want to buy from him is about 4-4.5" and the tail is actually a pale grayish color. Is this how the color is going to remain or does it get darker with age? Even the juvies have the dark black tail. I attached a couple of pictures of it. What do you guys think?
