About This Collection

Rainbowfish

Rainbowfish are active freshwater fish known for color, movement, and bold schooling behavior. Many species need more swimming room than typical nano fish, so tank size and group size matter when choosing the right rainbowfish for your aquarium. Smaller rainbowfish can work beautifully in planted community tanks with stable water, open swimming space, and peaceful tankmates. They are active fish that should not be crowded into undersized aquariums. Fish require Overnight shipping and are covered by our Live Arrival Guarantee. Check individual product pages for adult size, minimum tank size, group size, and temperament.
