Danio tinwini
A tiny danio, 2-3 cm SL, from streams in northern Myanmar, with rows of dark spots ringed in gold. Peaceful and suited to nano tanks, but prone to jumping.
Danio tinwini, the gold ring danio, was described in 2009 from the Mogaung Chaung in Kachin State, northern Myanmar, the same Irrawaddy tributary system as the glowlight danio. FishBase gives a maximum of 2.2 cm SL for males and 2.6 cm for females. Its lateral stripe is broken into spots that appear ringed in gold, giving it its name. Sharing features such as an absent lateral line and spotted pelvic fins, it is thought to be close to D. nigrofasciatus, though the patterns tell them apart. FishBase places it in Danio, while Seriously Fish uses Brachydanio. It is named after a collector and exporter of ornamental fish in Myanmar. Peaceful, it suits a community tank if companions match its tiny size. In Japan it is sold by specialist shops as a nano fish.

Omnivore (fine prepared foods, small frozen and live foods)
18-26°C, pH 6.5-7.5, 1-5 dGH (Seriously Fish). Its native waters are soft, so keep hardness low.
Seriously Fish suggests at least 45 x 30 cm for a group. Plant well over a dark substrate for colour. It jumps through small gaps, so fit a tight lid.
Peaceful but very small, so mix only with similarly tiny, peaceful fish, and keep it in a group.
Unfussy: fine prepared food as the staple plus small live or frozen foods such as baby brine shrimp and Daphnia.
Like other small danios it is presumably an egg scatterer without parental care; for fry, spawn it over mesh in a small container.
Small, timid fish can miss out at feeding time; feed small amounts spread across the tank.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Gold ring danio is 18〜26℃. Avoid sudden temperature changes and maintain a stable environment.
Gold ring danio typically reaches 2.2 cm SL (male), 2.6 cm SL (female) (FishBase) as an adult. Size may vary depending on care conditions and individual genetics.
Gold ring danio feeds on: Omnivore (fine prepared foods, small frozen and live foods). Aim for a balanced diet with appropriate feeding frequency.
