Glass Catfish (Kryptopterus vitreolus)

Glass Catfish is a freshwater ray-finned fish of the catfish family. They get their name from their translucent body that lets you see their organs and bones.

Unlike other typical catfish that you see sucking on rocks, tank sides and feeding on the bottom, this species although they do have barbels have chosen the free-swimming lifestyle instead.

The Glass catfish is a very peaceful and timid fish that keeps to themselves, only going for cover when disturbed, therefore, making a great addition to a community tank.

Natural Habitat

Glass Catfish inhabit moderate moving waters with plenty of plant coverage for shelter. They are found in river basins in the Cardamom Mountains and in rivers south of the Isthmus of Kra that drain into the Gulf of Thailand.

They mostly stay in the middle of the water column and rarely stray too far from the safety of the river bed.
