Rainbow Shiner
The Rainbow Shiner (Notropis chrosomus) is a native North American minnow that brings flashing breeding colors and constant activity to temperate aquariums. During breeding season, males develop iridescent electric blues, vivid pinks, and brilliant reds, producing a display rarely seen in cool-water species.
Behavior
Rainbow Shiners are schooling fish that need groups of at least 6, ideally 10 or more. They are peaceful, active, and constantly darting through the water column in tight schools.
Tank Setup
A 20 gallon long tank or larger suits a small school. They thrive in well-oxygenated water with moderate current, mimicking their native stream habitats. No heater required in most homes; they do well at room temperature (60 to 75°F).
Diet
Omnivorous and easy to feed. Quality flake, micro pellets, frozen daphnia, brine shrimp, and bloodworms all work well. Variety supports the brightest breeding coloration.
