Rainbowfish for Sale
Rainbowfish are brilliantly colored, active schooling fish native to Australia, New Guinea, and surrounding islands. On Light Fish you'll find a variety of rainbowfish listed by hobbyists and breeders, including Melanotaenia species (bosemani, neon, turquoise, praecox), Pseudomugil blue-eye species, and Celebes rainbowfish. Rainbowfish are known for their iridescent scales and tendency to display their best coloration in the presence of their own species.
All rainbowfish orders on Light Fish are backed by a platform-wide Live Arrival Guarantee. Fish are packed in breather bags with temperature-appropriate packs, shipped in insulated boxes via priority or overnight carrier, and weather-monitored along the route. Rainbowfish thrive in schools of six or more in well-planted tanks with moderate to strong water flow. Most species prefer neutral to slightly alkaline water (pH 7.0–8.0) and temperatures of 74–80°F.
