Identity and origin
- Origin
- Java and Bali; wider Southeast Asian records
- Identity
- Native regional barb; genetically diverse complex
A silvery barb known locally as wader or nyalian. Java–Bali genetic studies reveal deep population structure, so the familiar name must not erase locality differences. Larger than a typical nano fish: published maximum 20 cm standard length.
Habitat and care
Streams, rivers and lakes; Bali lake populations are documented. Habitat and identity reference
Provide a group, ample swimming space and suitable filtration. Preserve source locality rather than mixing unidentified regional lines.
Before choosing this species
Care-planning notes. Confirm exact requirements for the species and source population.
- Confirm the adult size and social behaviour of the exact species before planning its aquarium.
- Establish biological filtration and stable water conditions before introducing animals.
- Ask for locality, captive history and the actual animal’s feeding record; a catalogue image cannot provide these.
