Mine dosent have any lines or spots . Never seen any color change either . I,ve taken about 50 pics of him but he dosent like to pose so I can never seem to get all of him in one pic. This one is pretty close to his real color and the bright blue around the top and bottom of his fins shows a little in it .
Does your have interupted lines on the body?? And tiny spots on the head??
Mine also when mad and chasing another fish will change colors. The tail and head usually stay the same color but body color can become almost translucent or kind of like a mustand yellow. Thats only when it's being a meany.
They are a beautiful tang and even if mine is a bit of a meany I still love this fish.[/QUOTE]
