Daisy’s Blue Ricefish | Oryzias woworae
🔵⚫️🟥
With its shimmering blue scales and vivid red fin markings, this small ricefish from Muna Island, Indonesia, is a fascinating inhabitant of a planted freshwater aquarium.
A group of eight or more encourages confident behaviour and allows natural interactions to develop. Dense planting provides shelter, while open areas leave room for swimming. Choose small, peaceful tank mates that will not intimidate them or outcompete them at feeding time.
Maintain stable water conditions, gentle filtration and regular partial water changes. A temperature of approximately 23–27°C and a pH of 6.0–7.5 provide a suitable reference range. A well-established aquarium with consistent water quality is essential.

Food size matters: these fish have small mouths. Offer fine, high-quality flakes or microgranules, supplemented with appropriately sized live or frozen foods. Newly hatched Artemia, small Daphnia and Cyclops add variety and encourage natural feeding behaviour. Feed modest portions and check that every fish has access to food, especially in a community aquarium.
Fine-leaved plants and spawning mops can also provide places for egg deposition. Females may briefly carry a small cluster of eggs before attaching them to vegetation. If raising fry is the goal, a separate rearing setup improves their chances of survival.
