My blue discus and my red discus have white lines on the flat part of their body. they are about 2 and a half inches. Does this mean that they are growing, or a disease. http://www.rockymountaindiscus.com/images/34.jpg

It is perfectly normal and called the lateral line.
It stands out most on solid discus like yours. You can see it on other ones, too. And as Pat said, perfectly normal.
Thank you
