Pangio is a genus of small freshwater loaches recognized for their slender, eel-like bodies and gentle bottom-dwelling behavior in streams, forest waters, and aquarium environments. They often move close to the substrate, slipping between plants, driftwood, stones, and leaf litter while searching for small foods, which gives them a quiet but distinctive presence that differs from more actively swimming fish. Because Pangio species are generally peaceful and somewhat shy, providing soft substrate, secure hiding places, stable water quality, and appropriately sinking foods is essential for encouraging their natural foraging behavior and maintaining their health and subtle charm over the long term.
