Shipped at 1 inch, these juveniles are hardy and will grow to approximately 1–1.25 inches, with their soft coloration and delicate finnage becoming more defined as they mature.
Care & Aquarium Requirements:
Tennyo No Mai Ricefish thrive in soft to moderately hard, slightly acidic to neutral water (pH 6.0–7.5, temperature 72–78°F). They prefer tanks with fine plants, gentle flow, and open swimming areas. Peaceful and schooling by nature, they do best in groups of 6 or more, which encourages natural behavior and reduces stress.
Feeding & Diet:
These ricefish are omnivorous and thrive on high-quality micro-pellets, flake food, and live or frozen foods such as microworms, baby brine shrimp, or daphnia. Frequent small feedings help maintain health, growth, and vibrant coloration.
Breeding Information:
Females carry eggs externally before depositing them onto plants or spawning mops. Maintaining stable water conditions and providing live foods encourages successful breeding and ensures healthy fry growth.

About the name:
Heavenly Maiden (Tennyo): The ricefish’s shimmering body and delicate fins resemble the flowing robes of celestial maidens in Japanese folklore. They appear almost otherworldly when the light catches their scales.
Dance (Mai): Ricefish are known for their gentle, gliding swimming style. The Tennyo No Mai variety in particular has a graceful, floating movement that gives the impression of a serene “dance” in the water.
So the name “Dance of the Heavenly Maiden” highlights both their ethereal beauty and their elegant swimming motion, which is exactly why Japanese breeders chose it—it’s a poetic way of saying these are among the most graceful and enchanting strains of ricefish.
