The Rainbow Shiner is known from a variety of temperate fast-flowing habitats, including small rivers, springs, clear streams, creeks, and riffles. This is a peaceful shoaling species, which is best kept in groups of 6 or more. The aquarium should be spacious, mature, and well filtered. Be sure to provide the fish with plenty of hiding places (rocks, bogwood, robust planting) and a decent current from additional powerheads. The higher the temperature of the water, the greater the level of oxygenation that is required. Rainbow Shiners are primarily a mid to top dwelling species, and they would mix well with other fish of similar size and temperament and which enjoy the same fast-flowing conditions. Although the Rainbow Shiner is generally a peaceable species, long-finned tankmates are best avoided.
