Daisy's rice fish, scientifically known as Oryzias melastigma, are captivating small freshwater fish increasingly popular in home aquariums. Their vibrant personalities and relatively low maintenance requirements make them an excellent choice for both beginner and experienced aquarists. This comprehensive guide delves into everything you need to know about caring for these delightful creatures, ensuring your Daisy's rice fish thrive in your aquarium.
What are Daisy's Rice Fish?
Daisy's rice fish are a species of medaka, small, peaceful fish native to Southeast Asia. They're characterized by their slender bodies, typically ranging from 1 to 1.5 inches in length. Their coloration is generally a pale, translucent white or yellow, sometimes with subtle hints of olive or brown along their dorsal fins and back. While not as vividly colored as some other fish, their graceful movements and gentle nature are their main attractions. They're also known for their resilience and adaptability, making them surprisingly hardy for their small size.
What Do Daisy's Rice Fish Eat?
Daisy's rice fish are omnivorous, meaning they consume both plant and animal matter. A varied diet is crucial for their health and well-being. In the wild, their diet consists of small insects, crustaceans, algae, and detritus. In a home aquarium, a high-quality flake food formulated for small fish is a good staple. Supplement this with small live or frozen foods such as:
- Daphnia: A popular and nutritious option packed with protein.
- Brine shrimp: Another excellent protein source, readily available in most pet stores.
- Microworms: Tiny worms perfect for smaller rice fish or fry.
- High-quality fish flakes: Choose options specifically designed for small, omnivorous fish.
How Big Do Daisy's Rice Fish Get?
Daisy's rice fish typically reach a maximum length of around 1.5 inches (4 cm). Their small size makes them ideal for smaller aquariums, though they'll still appreciate a good amount of space to swim and explore.
How Long Do Daisy's Rice Fish Live?
With proper care, Daisy's rice fish can live for 2-3 years, sometimes even longer. Providing them with a clean, well-maintained environment and a balanced diet significantly impacts their lifespan.
What Tank Size Do Daisy's Rice Fish Need?
A 5-gallon tank is generally considered the minimum size for a small group of Daisy's rice fish. However, a larger tank is always preferable, allowing for more swimming space and reducing stress. For a group of 6-8 fish, a 10-gallon tank is a more suitable choice.
What Kind of Tank Mates Are Suitable for Daisy's Rice Fish?
Daisy's rice fish are peaceful community fish and are best kept with other similarly peaceful and small species. Avoid aggressive or larger fish that might see them as prey. Some suitable tank mates include:
- Other small, peaceful species of fish: Research compatibility carefully before introducing any new tank mates.
- Snails: These help keep the tank clean and provide additional interest.
How Often Should I Clean My Daisy's Rice Fish Tank?
Regular maintenance is essential for a healthy aquarium environment. Partial water changes (around 25-50%) should be performed weekly or bi-weekly, depending on the tank size and bioload. Regular cleaning of the gravel and removal of any uneaten food will help prevent the buildup of harmful substances.

What are the Signs of a Sick Daisy's Rice Fish?

If you notice any of these symptoms, it's crucial to isolate the affected fish and observe it closely. Consult a veterinarian specializing in aquatic animals if the problem persists.
