Overview
The queen danio is a fast, slim danio for an active community tank with room to swim. It asks a little more of its keeper than the easiest fish.
Did you know
The queen danio's species name, regina, is Latin for queen. It was chosen for the fish's graceful lines and the bands that run the length of its body.
Caring for the queen danio
Give queen danios a tank of at least 30 gal (115 L), so these restless danios can swim freely. Set it up with a good current, a base of sand and rounded gravel, and water-worn stone and driftwood. Keep planting to the sides and leave a long, open central lane, since they spend the day cruising rather than hiding.
Queen danios are powerful jumpers, like other danios, and can launch themselves clear of the water. A well-fitting lid is essential. Keep the water at 68 to 79°F (20 to 26°C) and a pH of 6.0 to 7.5. They eat almost anything and take flake, pellets, and frozen or live foods with enthusiasm.
Keep a group of at least six, and more where there is room. A larger shoal keeps them relaxed and shows off their shimmering stripes. They are fast, peaceful swimmers of the middle and upper water. They suit an active community of other robust, quick species rather than slow or delicate tank mates.
Queen danios are egg-scattering spawners that do not guard their eggs. They can be bred in a dedicated tank, which takes moderate effort.
Good to know
Devario regina is a slim, silvery danio in the family Cyprinidae. It is marked with iridescent blue-green and gold horizontal stripes that flash as it turns in the light.
In the wild
The queen danio is native to clear, flowing hill streams and rivers in Thailand and Myanmar. It lives over rock and gravel in cool to warm, well-oxygenated water.
