Overview:
The Stardust Ricefish is a captivating ornamental variety of the Japanese Ricefish, named for its shimmering, speckled appearance that resembles stars scattered across the night sky. With a translucent to light-colored body covered in sparkling iridescent flecks, it glitters beautifully under natural sunlight or aquarium lighting. Peaceful, hardy, and easy to breed, this variety is perfect for both aquariums and outdoor ponds.

Omnivorous and undemanding. Accepts flakes, micro pellets, and live or frozen foods such as baby brine shrimp, daphnia, and cyclops. A varied diet will enhance sparkle and overall health.
