Kryptopterus vitreolus, commonly known as the glass catfish, is native to the freshwater rivers and streams of Thailand. It is distinguished by its transparent body, through which internal organs and the spine are visible. This species is social, often found in schools, and relies on its barbels for navigation and food detection. Glass catfish play a role in controlling insect populations, feeding on larvae and small invertebrates.

Kryptopterus vitreolus, commonly known as the glass catfish, is native to Southeast Asia, specifically the Chao Phraya and Mae Klong river basins in Thailand.

The glass catfish typically inhabits freshwater environments characterized by clear, slow-moving rivers and streams. The water is usually warm with temperatures ranging from 24°C to 28°C (75°F to 82°F), and the habitat is often shaded by overhanging vegetation.

Kryptopterus vitreolus is a mid-water species that prefers areas with moderate to dense aquatic vegetation. It feeds primarily on small invertebrates and zooplankton. The glass catfish's transparent body provides camouflage against predators in the clear waters it inhabits, an adaptation that is crucial for its survival in its native habitat.
