The Banded Mountain Loach

The Banded Mountain Loach (Schistura notostigma) is a small, benthic freshwater species adapted to the fast-flowing streams of Sri Lanka’s wet zone. Using its body structure to anchor against currents, it feeds on algae and microinvertebrates along submerged surfaces.

Characterised by its banded pattern and distinct dorsal marking, this species is endemic to Sri Lanka and typically found only in clean, well-oxygenated forest streams, making it a reliable indicator of freshwater ecosystem health.
