Overview
The gold ring danio is a small, peaceful schooling danio that stays active most of the day. It is a good choice for a beginner.
Did you know
The gold ring danio is named for the broken pattern along its body, a row of dark blotches and dashes on pale gold. A zebra danio wears clean stripes instead. It was only described for science in 2007, and its species name honors Hla Tin Win, the Burmese collector who first found it.
Caring for the gold ring danio
Keep gold ring danios in a group of at least eight to ten, and more if you can. Bigger groups settle them down and bring out better color, while lone fish or small groups stay skittish. They swim through the middle of the tank.
Give them a planted tank of 11 gal (40 L) or more, with a darker substrate. Leave some open mid-water swimming room and keep the flow gentle to moderate. They are strong jumpers like other danios, so a tight-fitting lid is essential.
They handle a wide band of temperatures, from 64 to 79°F (18 to 26°C), so in a stable room a heater is often optional. Keep the water soft to moderately hard and slightly acidic to neutral, at a pH of 6.5 to 7.5. Feed small flakes, micro pellets and frozen treats such as daphnia or baby brine shrimp.
Gold ring danios are peaceful, but watch that they do not outcompete slow or shy tank mates at feeding time. They are egg scatterers with no parental care, and adults will eat their own eggs. Breeding them takes moderate effort.
Good to know

In the wild
Gold ring danios come from clear, slow streams in the Irrawaddy basin of northern Myanmar, around the Mogaung Chaung in Kachin State.
