Daisy’s Blue Ricefish (Oryzias woworae)

Add a touch of neon elegance to your aquarium with Daisy’s Blue Ricefish. This relatively recent discovery in the aquarium hobby has quickly become a favorite for its stunning iridescent blue body, which is beautifully contrasted by bright red-orange accents on the fins and throat. Whether you are a fan of planted nano tanks or looking for a peaceful schooling fish with a big personality, these "Medaka" relatives are a must-have.

Quick Stats & Origin

• Scientific Name: Oryzias woworae

• Origin: Found in the streams and ponds of Muna Island, Indonesia.

• Adult Size: Approximately 1–1.5 inches.

• Lifespan: 3–4 years.

Care & Environment

Daisy’s Blue Ricefish are incredibly adaptable and hardy, making them suitable for a wide range of aquarium setups. They are particularly popular for "low-tech" planted tanks because they thrive in calm water.

• Tank Size: A minimum of 10 gallons is recommended for a small school. They are active for their size and appreciate space to dart around.

• Substrate: Dark sand or nutrient-rich soil is ideal to make their blue iridescence truly shine.

• Environment: They love densely planted aquariums. Floating plants like Water Lettuce or Salvinia are excellent additions, as the ricefish enjoy swimming through the dangling roots.

• Water Parameters:

  • Temperature: 72°F to 82°F (22°C–28°C).

  • pH: 6.5–7.5.

  • Hardness: Soft to moderately hard.

Feeding & Diet

Ricefish are unfussy omnivores and have a surprisingly large appetite for such small fish.

• Daily Diet: High-quality micro-pellets, crushed flakes, or specialized Medaka food.

• Live/Frozen Foods: They absolutely thrive when supplemented with baby brine shrimp, daphnia, and cyclops.

• Surface Feeders: They have upturned mouths designed for feeding at the surface, so ensure your food choice stays afloat for a while.

Tank Mates

These are exceptionally peaceful fish that do best in a community of similarly sized, non-aggressive species.

• Ideal Partners: Celestial Pearl Danios, Ember Tetras, Microdevario kubotai, and Corydoras.

• Invertebrates: They are shrimp-safe for the most part, making them one of the best choices for high-end Neocaridina or Caridina shrimp colonies.

• Social Needs: They must be kept in a group of 6 or more. In a school, they are much bolder and the males will display more intense colors as they spar peacefully for attention.

Breeding

Daisy’s Blue Ricefish are famous for being one of the easiest egg-laying fish to breed in captivity.

• The Process: Females will carry a cluster of eggs attached to their vent before brushing them off onto fine-leafed plants or "spawning mops."

• Fry Care: Unlike many other fish, ricefish generally do not eat their own eggs, though they may go after the fry. For high survival rates, move the plants/mops containing eggs to a separate nursery tank. The fry are tiny and will need infusoria or powdered fry food initially.

Aquarist Tip: Daisy’s Blue Ricefish look their absolute best under LED lighting with a slight blue spectrum, which catches the metallic sheen on their scales and makes them glow like neon lights.
