has anyone have any idea why a bannerfish would loose it's white colouration .the face of my bannerfish has gone a very dark grey - almost black , and it's tail is going a dark grey.the stripe in the middle is still white and the yellow is not effected.my other two bannerfish are ok-all introduced together 6 months ago and all have healthy appitites
