Yokihi Medaka Rice Fish

Yokihi Medaka Rice Fish (Oryzias latipes) are a type of Japanese Rice Fish that bring movement, personality, and shimmering color to a planted aquarium or pond. We love these fish for their active swimming behavior, top-down viewing, and ability to flourish in a wide range of environments. Whether kept indoors or outdoors, Medaka are a fun fish that are rewarding to care for and easy to enjoy.

Unlike many traditional aquarium fish, Medaka tolerate cooler temperatures and adapt well to planted aquariums patio ponds, planted tubs, and indoor pond setups. Their peaceful nature, low bioload, and hardy disposition make them a great option for beginners while still being appreciated by experienced hobbyists and breeders.

Medaka Highlights
Beginner Friendly: Hardy and adaptable, Medaka are often recommended for newer hobbyists looking for an active and easy care fish.
Top-Down Viewing: One of the most enjoyable aspects of keeping Medaka is viewing them from above. Their colors and movement are ideal for shallow aquariums, ponds, and planted tubs.
Peaceful Temperament: Medaka coexist well with other peaceful livestock and are an excellent choice for community aquariums and ponds.

Medaka are social fish that should be kept in groups whenever possible. A group of six or more fish is recommended per 10 gallons to encourage natural behavior and activity. They prefer gentle water movement and will appreciate floating plants, live aquatic plants or additional cover, especially in outdoor setups. They may occasionally jump, so a lid or adequate plant cover s recommended.

Stocking Recommendations
As a practical guideline, plan for approximately one Medaka per gallon of water volume. Larger aquariums and ponds naturally provide more stability and swimming space. Avoid overcrowding as this can increase stress and make maintaining water quality more difficult.

Feeding
Medaka are omnivores and readily accept quality pellets, flakes, frozen and live foods. Feed only what they can consume in a few minutes and remove excess. Avoid overfeeding to help maintain water quality. If kept in outdoor setups, they will happily munch on mosquito larvae too!

Arrival & Acclimation
For best results, introduce new fish into a mature, cycled aquarium or pond. Spend extra time to float bags to match temperature before release. Once in the aquarium, pond or quarantine tank, give them time to settle in! Do not make any significant changes or move them during this time.

Care & Compatibility
Temperament: Peaceful
Diet: Omnivore
Group Size: 6 or more

Important Information: If using tap water, always treat with a quality dechlorinator. Stable water conditions, regular maintenance, and appropriate stocking levels will help support long-term health and success. As with all live animals, natural variation in color, pattern, and size should be expected.
