Care Summary
A hardy, golden-bodied schooling barb that has been in the hobby for over a century, most often sold in the bright xanthic 'Schubert's' form rather than its wild greenish colour. Peaceful, undemanding, and notably tolerant of cool water, it fills a useful niche as an active, colourful schooler for unheated or subtropical tanks where many tropical community fish would struggle. Males develop a warm red-orange flush along the belly when in good condition and competing for females. Like all barbs it is happiest and best-behaved in a proper school, and unlike most barbs it can be trusted in a peaceful community. A genuinely good, slightly old-fashioned choice that deserves more attention than the ubiquitous tiger barb.
Tankmates
One of the most peaceful barbs and a genuine community fish, in clear contrast to the tiger barb. Best in a group of six or more, where any mild fin-nipping tendency is redirected into the school rather than at tankmates; small groups are more likely to bother long-finned fish. A subtropical species that is comfortable at room temperature, which makes it an excellent choice for an unheated or lightly-heated tank in cooler Australian homes, alongside white cloud mountain minnows, danios, and other cool-water community fish. Avoid pairing with species that need consistently warm water, such as german blue rams or discus. Active and constantly grazing, and harmless to anything it cannot swallow.
