Distribution
The full extent of its range is unconfirmed but it appears native to central Vietnam where it's been recorded at several localities in Quang Nam province.
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 90 ∗ 30 cm36 ∗ 12 in are recommended. 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…

In terms of behaviour Sewellia spp. are perhaps the most dominant of the 'sucker belly' group of loaches though they're not generally aggressive towards dissim…
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
This is one of the more readily-available members of the genus and popularly referred to as S. sp. 'spotted' or S. sp. 'special'. It's superficially similar in…
