Rainbow Shiner
The rainbow shiner (Notropis chrosomus) is a small, vividly colored freshwater fish native to the cool, clear streams of the southeastern United States, particularly in Alabama and Georgia. Known for its spectacular iridescence, the rainbow shiner displays a range of colors depending on its mood and breeding condition, with males becoming especially vibrant, showing hues of pink, purple, blue, and red. They typically grow to about 2-3 inches in length, making them a manageable and eye-catching addition to freshwater aquariums.
Rainbow shiners are peaceful, schooling fish that do best in groups of six or more. They prefer a tank with moderate to fast water flow, replicating their natural habitat, along with plenty of open swimming space and some plants or rocks for cover. Ideal water conditions include temperatures of 68-75°F and a neutral to slightly alkaline pH of 7.0-8.0.
As omnivores, rainbow shiners thrive on a diet that includes high-quality flakes, pellets, and live or frozen foods like brine shrimp and bloodworms. Their stunning colors and lively, active nature make rainbow shiners an excellent choice for temperate community tanks, adding a unique pop of color and movement to aquariums.
