短腹爬岩鳅 (Sewellia breviventralis)

科: Balitoridae

短腹爬岩鳅为爬鳅科鱼类，平和的啃食者，争斗只是短暂推挤，原生分布于越南。喜欢急流、凉爽、高溶氧的水环境，高温是最大的敌人。成体约 3.8–5.6 cm，过于密集会不停推挤抢位，适宜水温 18–26 °C。水流、溶氧和低温，三者缺一不可。

原生生境

栖息地: Fast-flowing mountain streams, clinging to rocks
水流: Very strong, highly oxygenated current
溶氧: Requires very high dissolved oxygen

造景与硬件

底床: Bare rock and coarse gravel
硬景观: Large smooth boulders
水草: Minimal; algae-covered stones instead

性格食性与混养

群游性: Loosely social; crowding causes endless pushing
食性: Algae and biofilm specialist; supplement with wafers
推荐混养: Other cool-water stream fish — Share the need for oxygen and flow
避免混养: Large aggressive cichlids — Disrupt the calm grazing regime
