betta fish<\/a>\r\n\r\n prefer the red light? That would be most likely the most obvious answer, since the betta is one of the most popular fish on the market and one that everyone wants to own.<\/p>\nIf you were to actually take a closer look at the betta fish in your tank, would it be possible to actually see a color change?<\/p>\n
The betta\u2019s dorsal fin is actually a red-orange color. I would bet that they actually turn into a red color when they are under the red light. So, once you know where the best lives, you could take a red light and have it put a small red dot on the top of the betta\u2019s fin.<\/p>\n
Another way to have betta fish emit colored lights is to use an infrared red light instead of a regular red light.<\/p>\n
Infrared lights have a much longer wavelength than the red light does, so they are able to be reflected much more easily. There are also many different kinds of this kind of light, including a red light with a long wavelength and a blue light with a shorter wavelength.<\/p>\n
One very unique and unusual way to get colored lights to emit from your betta fish is to use white light. The white light can actually change the color of the fish.<\/p>\n
For example, a betta fish that lives in a tank with a red light can sometimes change from a bright red to a more intense orange, depending on the intensity of the red light. So, it would be nice to use these types of lights in a betta fish tank.<\/strong><\/p>\nOne last way to change the colors of your betta fish is to actually use specialized colored filters. If you look into betta fish filters, you will probably see a couple of different types of colored filters.<\/p>\n
Finally, if you want to try to make your betta fish emit more light, there are a few different types of betta fish lights to choose from. There are colored lights, fish lasers, and even more exotic types of filters that emit light.<\/p>\n
