Stinging catfish

The Stinging catfish, belonging to the Heteropneustes genus, is primarily a dark grey to black in color. This species is native to South and Southeast Asia, including countries such as India, Bangladesh, and Thailand. Characterized by its elongated body and the presence of sharp, venomous spines on its pectoral fins, the Stinging catfish is easily recognizable. Despite its intriguing appearance and unique defense mechanism, it is not particularly well-known or widely kept in the aquarium hobby, partly due to its aggressive nature and the potential danger posed by its venomous spines.
