Freshwater Rainbowfish • Community Species • Colour Display Fish • Active Schooling Swimmer
📋 The Red Rainbowfish (Glossolepis incisus) is a spectacular freshwater species renowned for its intense red coloration, especially in adult males. Native to Lake Sentani in Papua, this shimmering rainbowfish becomes increasingly colourful with age, diet quality, and lighting.
Red Rainbowfish are active schooling swimmers that thrive in spacious, well-oxygenated planted aquariums. Peaceful by nature, they mix well with other robust community fish but should be kept in groups to reduce stress and promote natural behaviour. Their long bodies and reflective scales produce vibrant flashes of colour with every movement.
A favourite among rainbowfish keepers, the Red Rainbowfish is a true centrepiece species for larger freshwater aquariums.
