The Daisy Ricefish (Oryzias woworae) is a distinctive freshwater aquarium fish valued for its appearance and behaviour. It is native to small freshwater streams on Muna Island, southeastern Sulawesi, Indonesia. Understanding its small natural habitat details helps aquarists provide the right flow, cover, food and tank mates.
Daisy Ricefish Size and Aquarium Setup
Adults reach about 3 cm (1.2 inches). A 38-litre (10-gallon) aquarium can hold a group, but a larger planted tank provides more room for displays. Keep at least eight fish and cover the tank securely. The aquarium should be fully cycled before the fish are added, and routine partial water changes should be used to keep nitrate and dissolved waste under control.
- Use a mature, fully cycled aquarium.
- Provide cover as well as open swimming or feeding space.
- Match filtration strength to the species’ natural habitat.
- Prevent sudden changes in temperature or water chemistry.
Water Conditions
Recommended conditions are 23–27°C (73–81°F), pH 6.0–7.5, with soft to moderately hard water. Good filtration and stable conditions are essential. Always acclimate new fish gradually and test ammonia, nitrite and nitrate, especially during the first weeks after introduction.
Diet and Feeding
The Daisy Ricefish should be fed micro pellets, crushed flakes, baby brine shrimp, daphnia, cyclops and small insect larvae. Offer portions that can be eaten promptly, vary the diet through the week and remove uneaten food before it affects water quality.

Sexing Daisy Ricefish
Males usually have stronger blue body colour, red-orange fin edges and longer dorsal and anal fins. Females are rounder and generally less colourful. Juveniles can be difficult to sex, so differences may only become clear as the fish mature.
Breeding
Females carry a cluster of fertilized eggs near the vent before attaching them to plants. Eggs can be collected from spawning mops and raised separately. Fry accept infusoria and then newly hatched brine shrimp. Consistent feeding and very clean water are usually more important than frequent handling or major changes to the aquarium.
Is It Good for a Community Tank?
Peaceful and active. They can share a tank with Norman’s Lampeyes, small rasboras, dwarf Corydoras and shrimp, provided tank mates are not large enough to eat them.
Species Variations and Albino Forms
Males vary from turquoise to deep metallic blue, and red fin colour can differ between lines. Albino Daisy Ricefish are not a commonly established aquarium strain.
Ease of Care
Care level: Beginner to intermediate. Success depends on choosing healthy stock, avoiding overcrowding and ensuring every fish receives suitable food. Observe the group daily for clamped fins, unusual hiding, rapid breathing or weight loss.
Frequently Asked Questions
How many Daisy Ricefish should be kept together?
Follow the species’ social needs described above and provide enough room for natural displays, feeding and escape from dominant individuals. A proper group usually produces more confident behaviour than keeping only one or two schooling fish.
Can Daisy Ricefish live in a beginner aquarium?
The listed care rating is a useful guide, but even beginner-friendly fish need a cycled tank and stable water. Species rated intermediate often have special feeding, flow or social requirements that should be prepared before purchase.
What is the best way to introduce Daisy Ricefish?
Dim the aquarium lights, acclimate gradually, and release the fish near cover. Feed lightly on the first day and watch existing tank mates for chasing or food competition.
