Daisys Ricefish

Rare, charming, and wonderfully unique — Daisy's Ricefish (Oryzias woworae) is a stunning nano fish from the island of Flores, Indonesia. Named after the researcher who helped describe the species, this tiny ricefish captivates with its vivid blue-green iridescence and warm orange-red accents — a remarkable colour combination for such a small fish. A prized gem for the planted nano aquarium.

Overview

Appearance

Males are the stars of the show — displaying a vivid electric blue-green body with striking orange-red fin edges and a warm flush of colour along the belly. Females are slightly more subdued but still attractive with their iridescent blue sheen. When kept in groups under good lighting, a school of Daisy's Ricefish creates a shimmering, jewel-like display that is truly breathtaking for such a small fish.

Water Parameters & Tank Setup

• Temperature: 72 – 82°F (22 – 28°C)
• pH: 7.0 – 8.0
• General Hardness (GH): 6 – 20 dGH
• Tank Size: Minimum 10 gallons for a group of 8+
• Lighting: Moderate to bright — brings out their iridescent blue colouration
• Substrate: Dark substrate enhances their vivid colours
• Plants & Decor: Floating plants, Java moss, and fine-leaved stem plants for a natural feel and spawning sites

Diet & Feeding

Daisy's Ricefish are surface and mid-water feeders:

• Staple: High-quality nano fish flakes or micro pellets
• Treats: Baby brine shrimp, daphnia, micro worms, and mosquito larvae

Feed small amounts 2–3 times daily.

Compatibility & Tank Mates

Peaceful and well-suited to nano community tanks. Good tank mates include:

• Other small ricefish and medaka varieties
• Nano fish (Chili Rasboras, Ember Tetras, Pygmy Corydoras)
• Neocaridina dwarf shrimp
• Small snails

Avoid housing with larger or boisterous fish that may outcompete them.

Breeding

Daisy's Ricefish breed readily in a well-maintained aquarium. Females carry fertilized egg clusters attached to their belly before depositing them on fine-leaved plants or moss. Eggs hatch in 10–14 days. Fry are tiny — feed infusoria or liquid fry food initially, then graduate to baby brine shrimp.

Daisy's Ricefish is a rare and beautiful nano fish that rewards its keeper with stunning colour and lively, social behaviour. A true collector's species that deserves a place in every planted nano aquarium.
