Stunning in planted tanks
Peaceful community fish
Rainbow Shiners (Notropis chrosomus) are a North American native schooling fish with metallic silver-blue sides and brilliant pink-to-red fins that intensify during breeding season. They’re an increasingly popular choice for planted coldwater setups — and one of the few truly stunning native fish that thrives in a standard aquarium.
They’re undemanding, active, and peaceful. Being coldwater fish, they don’t need a heater in most home environments and are compatible with other coldwater or room-temperature species. Like most schooling fish, they’re best kept in groups of 8 or more where their natural shoaling behavior fully expresses.

Species Spotlight
Why We Love This Fish
01
Stunning Native Color
Metallic silver-blue with vivid pink-to-red fins that intensify with mood and season — a combination you don’t find in most tropical schooling fish.
02
No Heater Required
Rainbow Shiners are coldwater fish that thrive at room temperature. No heater needed in most home setups — a real advantage for unheated planted tanks.
03
Active Schoolers
A group of 10 or more Rainbow Shiners in a planted tank is constantly in motion — coherent, fast-moving, and visually impressive from across the room.
Community Tank
Compatible Tank Mates
These nano fish coexist well with shrimp and other peaceful invertebrates.
Keep 10 or more for the best schooling behavior — smaller groups tend to be nervous. A planted tank with open swimming space in the mid-column and some current suits them well. No heater needed in most home setups; aim for 60–72°F.
