3. Diet and Feeding
- Diet: Medaka Rice Fish are omnivorous, feeding on small insects, algae, and plant material in the wild. In captivity, they accept a variety of foods, including:
- High-quality micro-pellets or flakes
- Live or frozen foods like brine shrimp, daphnia, and bloodworms
- Finely chopped vegetables such as spinach or zucchini
- Feeding Schedule: Feed small portions 1–2 times daily to avoid overfeeding and maintain water quality.
4. Compatibility with Other Fish

- Neon Tetras

- Shrimp species (e.g., Amano or Cherry Shrimp)
- Snails like Nerites or Mystery Snails
- Avoid: Larger or aggressive species that may view Medaka as prey or outcompete them for food.
5. Common Challenges and Tips
- Breeding: Medaka are prolific breeders, laying eggs that attach to the female’s body before being deposited onto plants or substrate. Providing plenty of vegetation or a breeding mop encourages reproduction. The eggs hatch in 7–14 days.
- Water Quality: Medaka are hardy but thrive best in stable, well-maintained conditions. Regular water changes (20–30% weekly) and monitoring parameters are essential.
- Temperature Extremes: While adaptable, avoid prolonged exposure to extreme temperatures to prevent stress.
