The Red Ricefish (Oryzias woworae) is a small freshwater fish that belongs to the family Adrianichthyidae. Native to Indonesia, specifically in the Sulawesi region, these fish are often found in rice fields, swamps, and other slow-moving bodies of water. Here are some key points about the Red Ricefish:

1. Size and Appearance:

   • Red Ricefish are relatively small, typically reaching a maximum size of around 1 to 1.5 inches (2.5 to 3.8 cm).
   • They have a slender body with a forked tail and a relatively short lifespan of around 1 to 2 years.

2. Coloration:

   • As the name suggests, the Red Ricefish is known for its vibrant red coloration. The males are generally more brightly colored than the females, and during breeding seasons, their colors may intensify.

3. Habitat and Range:

   • Red Ricefish are native to the freshwater habitats of Sulawesi, Indonesia. They are often found in rice paddies, swamps, and slow-moving streams.

4. Tank Setup:

   • These fish are suitable for small aquariums, and they do well in planted tanks with gentle filtration.
   • A well-planted tank with hiding spots and floating plants can mimic their natural habitat and provide them with a sense of security.

5. Water Parameters:

   • Red Ricefish prefer slightly acidic to neutral water conditions with a pH range of 6.0 to 7.5.
   • The water temperature should be kept between 72°F to 82°F (22°C to 28°C).

6. Diet:

   • Red Ricefish are omnivores and will eat a variety of foods, including small live or frozen foods, as well as high-quality dry flakes or pellets.
   • Offer a varied diet to ensure they receive the necessary nutrients.

7. Social Behavior:

   • These fish are generally peaceful and can be kept in groups. However, it's recommended to have more females than males to reduce aggression.
   • They are schooling fish, so keeping them in groups of at least six individuals is advisable.

8. Breeding:

   • Red Ricefish are known for their interesting reproductive behavior. Males build bubble nests, and the females lay their eggs in these nests.
   • The parents do not provide care for the eggs or fry, so it's common practice to separate the adults from the fry to prevent predation.
