Species Spotlight
Why We Love This Fish
01
Iridescent Blue + Red Fins
The metallic blue-green body and deep red fins shift with light and angle. In a planted tank with good lighting, Red Neon Rainbowfish are genuinely hard to look away from.
02
Great Community Fish
Peaceful, active, and compatible with most other community fish. They add mid-column movement without causing problems for tankmates.
03
Schooling Display
A group of 10 or more Red Neon Rainbowfish creates a constant, coordinated swimming display that fills the mid-column of any planted tank.
Community Tank
Compatible Tank Mates
These nano fish coexist well with shrimp and other peaceful invertebrates.
