Sales Description
The Gold Ring Danio (Brachydanio tinwini) is a small, energetic schooling fish known for its striking pattern of golden ring-like spots set against a silver-to-bronze body. Native to fast-flowing streams in Myanmar, this species is a favorite among nano tank keepers and aquascapers for its beauty, hardiness, and nonstop activity.
Despite their tiny size, Gold Ring Danios have bold personalities and do best in groups of 6 or more, where their schooling behavior really shines. Their active swimming and shimmering patterns make them a fantastic choice for planted aquariums, and they coexist peacefully with most community fish and invertebrates.
