A rainbow is a meteorological phenomenon that forms when sunlight is refracted, reflected, and dispersed in water droplets, creating a spectrum of light. The height of a rainbow is determined by the angle of the sunlight and the location of the observer. Typically, rainbows are seen in the sky, but they can also form in mist or spray, such as at the base of a waterfall. The height of a rainbow is limited by the distance between the observer and the water droplets that refract the sunlight, so it can appear to be as high as the observer's line of sight. **

Additionally, regular water changes and proper filtration are essential for maintaining a healthy environment for both species. **
