科: Balitoridae
白背爬岩鳅为爬鳅科鱼类，安静但会守护自己选定的栖石，原生分布于越南。吸盘状腹部为适应山溪急流而生，温暖静水对它比疾病更致命。成体约 4.8–7 cm，单养或松散小群，取决于石头数量，适宜水温 18–26 °C。水流、溶氧和低温，三者缺一不可。
Sewellia albisuera, a member of the family Balitoridae, is native to Vietnam. Its sucker belly is made for mountain rapids — still, warm water suffocates it faster than any disease. It lives on the bottom. Adults reach 4.8–7 cm. Singly or in a loose group on open rockwork. Provide strong flow, cool temperatures and mature algae-covered rockwork; keep it below 26 °C. Maintain 18–26 °C at pH 6.5–7.5. Water quality and diet matter more than décor.
