There are many rice fish types, from metallic golds to koi-style patterns, so you can create a tank that feels lively, elegant, and uniquely yours. In this guide, we’ll break down the most popular types of rice fish (including trending medaka ricefish varieties), plus practical care tips to keep them thriving. If you’re looking to add movement, color, and calm energy to your aquarium, these types of Japanese rice fish are a perfect place to start.
Overview of Rice Fish
Rice fish (Oryzias latipes), commonly called Medaka ricefish or Japanese ricefish, are small freshwater fish originally from East Asia and have been selectively bred for many generations. Today’s aquarium strains come in a wide range of colors, body sheens, and pattern types, making them one of the most underrated “designer” nano fish for planted tanks.
Ricefish are especially popular because they’re:
- Hardy and adaptable to a variety of water conditions
- Peaceful community fish (great with shrimp-friendly tankmates, depending on size)
- Active but not aggressive, usually swimming in the top and mid water column
- Schooling fish that look best in groups
- Often easier to keep than many nano fish, especially for beginners
Most ricefish stay around 1–1.5 inches, which makes them ideal for nano tanks, patio tubs, and planted aquariums. If you’ve ever wanted a fish that feels “low stress” but still looks premium, Japanese ricefish fit the bill.
Daisy Blue Ricefish
Daisy Blue Ricefish are a standout among modern rice fish varieties, known for their soft blue shimmer that looks almost metallic under LED lighting. In the right setup, the blue tone appears deeper and more luminous, especially when paired with dark substrate and green plants.
This variety is ideal for aquarists seeking a calm, elegant appearance rather than neon-bright colors. Daisy Blues tend to look best in groups, where the subtle shine becomes more noticeable as they move together across the tank. They also pair beautifully with aquascapes featuring moss, Anubias, and floating plants that diffuse light and create a natural environment.
Medaka Koi Ricefish
If you love koi patterns but don’t have space for a pond, Medaka Koi ricefish give you that koi-style look in a nano-sized fish. Among the most popular types of medaka rice fish, this variety features white, red, and orange patterning that resembles classic koi markings.
Medaka Koi ricefish are a fantastic choice for aquariums designed for high contrast, think light sand, smooth stones, and bright green carpeting plants. They also perform extremely well in outdoor tubs where natural sunlight enhances their coloration and pattern definition.
Because koi-pattern fish can vary widely, selecting a uniform group can create a “designer school” effect that dramatically upgrades the look of a planted tank.
Medaka Youkihi Ricefish
Medaka Youkihi ricefish are known for their warm, glowing orange to golden-red coloration. This is one of the most attention-grabbing rice fish types because the color reads well even from a distance, perfect for aquariums placed in living rooms, offices, or store displays.
Youkihi ricefish often look best in tanks with:
- Dark backgrounds
- Black or deep-brown substrate
- Medium lighting that enhances warm tones
- Plants like Java fern, Anubias, or floating plants for gentle shade
If your goal is maximum color without the aggression of some other “bright” fish species, this is one of the best types of Japanese rice fish to consider.
Black Medaka Ricefish
Black Medaka ricefish offer a sleek, dramatic look that instantly makes aquascapes feel modern and high-end. Their deep, dark coloration creates strong contrast against bright plants and lighter substrates, and they’re especially popular in minimalist aquascapes where every detail matters.
This variety is also excellent for top-view tanks and outdoor tubs because their dark bodies remain visible under different lighting conditions. In aquariums with floating plants, their color looks even richer, creating a calm but striking vibe.
Gold Medaka Ricefish
Gold Medaka ricefish is one of the most classic and beginner-friendly types of rice fish. Their bright golden sheen reflects light beautifully, creating a sparkling effect when the school moves together. They’re a great “centerpiece school” for nano tanks because they bring brightness without overwhelming the aquascape.
Gold Medaka are also ideal for aquarists who want fish that photograph well for social media or product displays, especially when paired with green plants and clean glass.
Tips to Care for Rice Fish
Ricefish are hardy, but they still thrive best when their environment matches their needs. Here’s what matters most for long-term success with rice fish medaka and other medaka ricefish varieties.
Tank Size and Grouping
Ricefish are schooling fish and look best in groups of at least 6. While they can live in nano tanks, they’re more confident and active with space and a proper group size.
Water Parameters
Ricefish tolerate a wide range, but stability is key. A stable temperature and consistent water quality prevent stress, improve coloration, and support breeding behavior.
Filtration and Flow
Use gentle filtration with steady oxygenation. Ricefish do well with mild water movement, but strong currents can tire them out in small tanks.
Feeding
Offer a varied diet of high-quality nano pellets, crushed flakes, and occasional frozen foods like brine shrimp or daphnia. A diverse diet improves color, body condition, and activity.
Planting and Cover
Ricefish love planted tanks. Floating plants are especially helpful because they reduce harsh light and make fish feel more secure, which often improves color and natural behavior.

Rice Fish Types Frequently Asked Questions (FAQs)
How many types of rice fish are there?
There are many types of rice fish in the aquarium hobby, including dozens of selectively bred medaka ricefish varieties. Common types include gold, black, koi-pattern, orange (Youkihi), and multiple shimmer or metallic lines. New ricefish varieties continue to be developed through selective breeding.
Can I keep these Rice fish varieties together?
Yes, most types of Japanese rice fish can live together peacefully as long as the tank is large enough and they are kept in proper groups. Mixing varieties is common and can create a beautiful “designer school” effect. For the cleanest look, many aquarists keep one variety per tank, but mixing is generally safe.
How many Rice fish should I keep in a 5-gallon tank?
A 5-gallon tank can typically hold 5–6 ricefish if filtration is strong and water quality is well maintained. Since ricefish are schooling fish, fewer than 5 may lead to shy behavior and less activity. If you want the fish to look and behave their best, consider upgrading to 10 gallons for a larger school.
