Olive Barb (Systomus sarana) Care Guide
Systomus sarana, the olive barb, is a large, robust South Asian cyprinid of rivers and lakes that needs a very spacious aquarium.
Overview
The Olive Barb (Systomus sarana) is a large, robust cyprinid widespread across South Asia. Adults are active and somewhat boisterous, reaching a considerable size that places them firmly among the larger barbs. The species is popular as food and as a gamefish in parts of its range but is comparatively uncommon in the aquarium hobby, where only small specimens see limited demand.
Taxonomy
- Family: Cyprinidae
- Genus: Systomus
- Scientific name: Systomus sarana
- Common synonyms: Puntius sarana, Barbus sarana, Cyprinus sarana
Habitat
Systomus sarana is native to Afghanistan, Pakistan, India, Nepal, Bangladesh, Bhutan and Sri Lanka, with reports from Myanmar and Thailand. It is a benthopelagic species of rivers, streams, lakes and backwaters and tolerates a degree of salinity, even entering brackish water. Adults form loose schools of a few to several dozen individuals.
Tank requirements
- Minimum tank volume: 500 L
- Temperature: 22-28 °C (72-82 °F)
- pH: 6.5-7.8
- GH: 5-18 °dGH
- School size: 6 or more individuals
- Lifespan: 8-12 years
The species is recorded reaching up to 42 cm total length according to FishBase, so a very large tank and strong filtration are essential for long-term care.
Diet
The olive barb is an omnivore. In the wild it feeds on aquatic insects, small fish, algae and shrimps. In captivity it accepts a varied diet of quality dried foods, frozen and live items and vegetable matter, fed about twice daily.
Compatibility
Although broadly peaceful, this is a large, active mid-water fish that needs space and the company of similarly sized, robust cyprinids. Small fishes are liable to be outcompeted or treated as prey and should not be housed with it.
Breeding
It is an egg-scatterer that spawns in running waters among submerged boulders and vegetation, providing no parental care.
Conservation status
IUCN Red List: Least Concern (assessed 2019). The species remains widespread and is commercially important in parts of South Asia.
