The Dwarf Neon Rainbowfish (Melanotaenia praecox) is one of the most eye-catching rainbowfish available, combining an iridescent electric-blue body with vibrant red fins. Active, peaceful and always on the move, they make a stunning addition to well-planted community aquariums.
Best kept in groups of at least six, these social fish display their brightest colours when housed with their own kind. They thrive in clean, well-oxygenated water with plenty of swimming space, while plants and décor provide security without restricting their natural activity.
Dwarf Neon Rainbowfish are easy to care for and readily accept a varied diet of high-quality flakes, micro pellets, frozen and live foods. Regular water changes and a nutritious diet help maintain their incredible metallic sheen and encourage natural display behaviour.
