Description
The Rainbow Shiner is a small, peaceful cyprinid species native to the clear, shallow streams of the Southeastern United States. Best known for the males’ vibrant iridescent display of pinks, purples, and electric blues during the breeding season, this freshwater fish brings unmatched color and energy to cool water and planted aquariums.
Highly adaptable and outgoing, Rainbow Shiners are perfect for room temperature or subtropical setups. They thrive in planted aquariums and do well in groups of 6 to 10 or more, showing their best schooling behavior and coloration in larger numbers. With a peaceful temperament and active nature, they make ideal tankmates for ornamental shrimp, hillstream loaches, Stiphodon gobies, and other small, non-aggressive species.
Rainbow Shiners are typically found swimming in the middle and upper levels of the aquarium, but will also forage near the substrate. They are neither aggressive nor overly shy, making them a favorite among aquarists who enjoy fish with personality and color.

They are peaceful schooling fish that do well with similar-sized, non-aggressive tankmates like White Cloud Mountain Minnows and small Danios. These fish thrive in unheated, well-oxygenated aquariums and require a varied omnivorous diet for optimal health and coloration.
Will Rainbow Shiners eat shrimp?

For the best results, provide plenty of aquatic plants and hiding spots to help baby shrimp survive in a shared aquarium.
