i've always wondered why certian fish, espeically asian aro's, have a dark area on the upper part of their body? does it have something to do with them always swimming on the surface? or is it genetic? makes them look alot bigger for some reason.
well, not all of em have this dark strap that you talk about, like the crossbacks and reds, hell, even the greens and i.5 reds(grade2) have clear backs when they mature, the only one that really exibits this chracteristic would be the red tail gold, or rtg as most people would call em..a "classic" rtg would have gold only appear till the 4th level of it's scales and the 5th and 6th would be totally dark, tanning would however cause it to be darker
i have seen silvers with this i thnk KOD had a silver with a dark back.
i want to tan the back of my RTG but will wait a while as it is starting to show some 5th level shine and i dont want to stop that.
