The gold tetra, also called the brass tetra or the golden tetra, is often found in the trade as an imported tank raised species. Unfortunately the bred tetras simply do not have color. We import wild gold tetras from Brazil where they tend to have the most color. Size can vary within on school of fish since they are wild caught, but these fish will hold their magnificent 24 kt color. Actually the color shade varies depending upon where they are caught, hence sometimes they are gold, sometimes brass. These are peaceful fish that will not even harm nano tank species but fast enough to be kept with small and mid-size cichlids.
