Banjars and green are almost the same, they have silvery color from all levels of scales, some banjars are mistaken as red by the novice eye, since they have reddish coloration in their scales and fins (some calls it low grade red) some have a very nice yellow fin. So to answer your question.. there is no HB or xb banjars. Pretty much their scales would stay the same when til they mature, it might improve but.. barely. Unlike RTG's and HBRTG's the level of shine and gold tone improves as it mature. Normally RTG and HBRTG have greyish base color covered with gold scales. XBs have gold base and blue base.
