Rainbow boa
These snakes, although they are predators, are actually absolutely harmless, since they have no poison. Rainbow boas are often kept in terrariums at home, because their appearance really is conducive to this. The thing is that the scales of this snake are «metal», which is why they play in the sun and shimmer with all the colors of the rainbow. Moreover, the brighter the sun shines, the more interesting combinations the color of this snake can give out.
