Jim,

Sometimes when the fish swim to a certain point at the back of the aquarium they get a white outline around them that disappears when they swim forward again. It is noticeable on a few of the fish, but most noticeable on the blue damsels. The flame angel and squarespot anthias are others that this is fairly noticeable on.

I've included a couple of screen shots.

Regards,

Justin
