Known by some as veil tail, this is one of the most popular fish because they are owners of a beauty that is very difficult to match, and very easy to care for.
These fish have three types of basic aspects that are metallic; The fish have bright color, similar to a metal object, so they are very bright, due to the presence of guanine in their color scale. The second aspect is matte, these fish lack scales, so there is nothing that reflects the light in them, and that is why they are matte. And the last aspect, which is the pearly, which is the combination of the two previous aspects, in random proportions, which produces a reflective and non-reflective scale in the same dancer fish.
