The Javanese Ricefish is a rare and fascinating species of ricefish, appreciated for its adaptability, peaceful nature, and subtle beauty. Native to brackish and freshwater habitats of Southeast Asia, these small fish display a shimmering silvery body with delicate hints of gold or green under the right lighting. Hardy and versatile, they are an excellent choice for aquarists looking to add a unique species that thrives in both planted aquariums and lightly brackish setups.
We ship Javanese Ricefish at about 1 inch, a perfect juvenile size for safe acclimation and long-term growth. Adults typically reach around 1.5–2 inches, remaining compact and ideal for nano aquariums or larger peaceful community tanks. Their calm temperament and schooling behavior make them best kept in groups of 6 or more, where they will display natural activity and confidence.
Javanese Ricefish are remarkably hardy compared to many small tropical fish, capable of adapting to a variety of water types, including slightly brackish environments. They thrive in aquariums of 10 gallons or larger, with live plants, floating vegetation, and open swimming spaces. A tight-fitting lid is essential, as ricefish are natural jumpers.
Temperature: 70–82°F (21–28°C)
pH: 6.5–8.0
GH: 5–15
KH: 3–10
These omnivores accept a wide variety of foods. A balanced diet of high-quality micro pellets, crushed flakes, and frozen/live foods such as baby brine shrimp, daphnia, and mosquito larvae will keep them vibrant and active.
Like other ricefish, the Javanese Ricefish is an egg-scattering species. Females often carry their eggs attached near the vent before depositing them on plants or other surfaces. In a well-planted tank, fry may survive without intervention, though breeders often collect eggs for higher hatch rates.
