Schistura cryptofasciata
Schistura cryptofasciata is a small stone loach native to fast‑flowing freshwater streams in Southeast Asia. It reaches just 9.3 cm, lives among rocks and gravel, and is prized by anglers for its subtle behavior rather than its size. Though not a table fish, it provides a fun, light‑tackle challenge.
