I was recently at a LFS, and the had two Aros in two different tanks. One was labeled Black Aro and the other a Sliver Aro. They both looked almost the smae in color and pattern. They were both blackish in color with blueness towards the fins and orangeish color by the tip. My first though was that someone made a mistake. But it being a very established LFS I doubt that was the case. I didn't have a camara with me. I was told the Sliver may kept its color and not turn all sliver. I love t he color and I don't want to take a chance that it will lose its appearance.
