Ulysses Medaka

Name: Medaka Ricefish

Max Size: Medaka ricefish, also known as Japanese ricefish or Oryzias latipes, are small fish that typically reach a size of about 1.5 to 2 inches (3.8 to 5 cm) in length.

Water Parameters: Medaka ricefish thrive in water with a pH range of 6.5-7.5 and a temperature between 68-78°F (20-26°C). They prefer slightly soft to moderately hard water conditions.

Diet: These omnivorous fish have a varied diet. In the wild, they consume insects, zooplankton, algae, and plant matter. In an aquarium, they will accept high-quality flakes, pellets, live or frozen foods like brine shrimp and daphnia, and occasional vegetable matter.

Temperament: Medaka ricefish are peaceful and non-aggressive, making them suitable for community aquariums. They are known for their calm and friendly demeanor, rarely showing aggression towards tankmates.

Schooling or Non-Schooling Fish: Medaka ricefish are non-schooling fish. While they don't form tight schools, they enjoy the presence of their own kind and thrive better when kept in small groups.

Possible Types of Tank Mates: Medaka ricefish can be kept with other peaceful community fish of similar size, such as small tetras, rasboras, and other peaceful dwarf fish. Avoid aggressive or fin-nipping species.

Tank Setup: Provide a well-planted aquarium with ample hiding spots and floating plants to mimic their natural habitat. They appreciate a sandy or fine gravel substrate. A gentle water current and regular water changes are important for their well-being.

Behavior: Medaka ricefish are active swimmers and tend to occupy the upper to middle levels of the water column. They may exhibit interesting courtship behaviors, and males often display colorful patterns to attract females.

Fun Fact: Medaka ricefish have been extensively studied in scientific research due to their transparent bodies, which make them ideal for observing internal processes and genetic traits. They are also known for their ability to tolerate a wide range of environmental conditions, including low oxygen levels and temperature fluctuations.
