Glass Catfish

The Glass Catfish (Kryptopterus vitreolus) is one of the most unique freshwater fish in the aquarium hobby, known for its almost completely transparent body where the spine and internal organs are visible. This fascinating appearance gives the fish a delicate, ghost-like look that stands out in any aquarium.

Native to Thailand, Glass Catfish inhabit slow-moving rivers and streams with dense vegetation. In the aquarium, they thrive in well-planted tanks with gentle water flow and stable water conditions.

Unlike most catfish, Glass Catfish are mid-water schooling fish, often seen swimming together in tight groups. Their calm and peaceful nature makes them an excellent addition to community aquariums.
