lineolata: from the Latin linea, meaning 'line', and -ola, the latter a suffix used to indicate small size.
Distribution
Native to Vietnam where it's known from the provinces of Thua Thien-Hue (Huong river drainage), Quang Nam (Thu Bon river), Quang Ngai (Tra Khuc and Ve rivers) …
Habitat
Restricted to shallow, fast-flowing, highly-oxygenated headwaters and tributaries characterised by stretches of riffles and runs broken up by pools or cascades…
Aquarium size
Minimum base dimensions of 75 ∗ 30 cm30 ∗ 12 in are recommended for general care. Smaller tanks can be used for breeding.
Maintenance
The water must be clean, well-oxygenated, and ideally turn over 15-20 times per hour so we suggest the use of an over-sized filter as a minimum requirement plu…
Water conditions
Temperature: Can tolerate higher temperatures provided its oxygen requirements are maintained but for general aquarium care a value of 20 – 24 °C68 – 75 °F is …
Diet
Much of the natural diet is composed of benthic algae plus associated micro-organisms although insect larvae are probably taken on an opportunistic basis. Home…

Sexual dimorphism
The most obvious external characteristics are the shape of the head and body when viewed from above, with females having a comparatively broad body and a snout…
Reproduction
Sewellia spp. are arguably the easiest of all loach species to breed in aquaria and success has been achieved with several species. Initial reports mostly desc…
Notes
S. lineolata was first recorded by Diard over 150 years prior to its 'rediscovery' in the early-1990s. It became available to the aquarium trade in the mid-200…
